Maybe you can try swapping your dtb file with the one supplied in one of the images above or just try any of them. You will lose some peripherals, but at least you can understand if it is just a hardware description problem or something more serious. edit: also, reading from the rk3288 datasheet I understand that i2c bus at address 0xff170000 is the bus designated for HDMI DDC, so there are no chances to change it in the device tree

Is it possible to patch the device tree someway to enable HDMI output and having the console on the framebuffer for debugging in current non-development armbian version? Thanks

I guess there is something wrong with the i2c driver. This is the output I can gather using the armbian image with 4.4.126 kernel: root@xt:/home/paolo# dmesg | grep i2c [ 2.876359] i2c /dev entries driver [ 2.877897] of_get_named_gpiod_flags: can't parse 'vsel-gpios' property of node '/i2c@ff650000/syr827@40[0]' [ 2.877913] of_get_named_gpiod_flags: can't parse 'vsel-gpio' property of node '/i2c@ff650000/syr827@40[0]' [ 2.881312] of_get_named_gpiod_flags: can't parse 'vsel-gpios' property of node '/i2c@ff650000/syr828@41[0]' [ 2.881328] of_get_named_gpiod_flags: can't parse 'vsel-gpio' property of node '/i2c@ff650000/syr828@41[0]' [ 2.908968] rk3x-i2c ff650000.i2c: Initialized RK3xxx I2C bus at f0fba000 [ 2.910075] rk3x-i2c ff140000.i2c: Initialized RK3xxx I2C bus at f0fbc000 [ 2.911169] rk3x-i2c ff160000.i2c: Initialized RK3xxx I2C bus at f0fbe000 [ 2.912242] rk3x-i2c ff170000.i2c: Initialized RK3xxx I2C bus at f0fd2000 [ 2.913370] rk3x-i2c ff660000.i2c: Initialized RK3xxx I2C bus at f0fd4000 [ 8.226809] i2c i2c-6: Added multiplexed i2c bus 7 [ 8.228102] i2c i2c-6: Added multiplexed i2c bus 8 root@xt:/home/paolo# i2cdetect -y 5 0 1 2 3 4 5 6 7 8 9 a b c d e f 00: -- -- -- -- -- -- -- -- -- -- -- -- -- 10: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 30: -- -- -- -- -- -- -- 37 -- -- -- -- -- -- -- -- 40: -- -- -- -- -- -- -- -- -- -- 4a 4b -- -- -- -- 50: 50 -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 70: -- -- -- -- -- -- -- -- root@xt:/home/paolo# get-edid -b 5 | parse-edid 5 This is read-edid version 3.0.2.

I get devices at addresses 37 and 50 as you described and get-edit tool works fine. Also data is correctly reported (display name, modelines, etc...) The i2c6 bus appearing in your test can be probably explained taking a look to the kernel documentation. I found this in the device tree documentation: so that bus is directly embedded into the HDMI controller and spawns up when there is not a master i2c bus for EDID, which is what you did removing the line from the device tree. From what I understand, that works but is suboptimal. To satisfy my curiosity I will try swapping the buses to see what happens. In the meantime you may do tests with another HDMI cable, it is quite common that faulty or cheap cables causes many kinds of issues (HDMI CEC not working or working intermittently for example...) Check the u-boot device tree for &pinctrl section. You'll find these lines: &pinctrl { u-boot,dm-pre-reloc; pinctrl-names = "default"; pinctrl-0 = <&power_led>, <&pwr_hold>; ... act8846 { /* * Original q8 device tree says: * - gpio0 11 HIGH -> power hold * - gpio7 1 LOW -> possibly pmic-vsel, we omit it here */ /*pmic_vsel: pmic-vsel { rockchip,pins = <7 1 RK_FUNC_GPIO &pcfg_output_low>; };*/ pwr_hold: pwr-hold { rockchip,pins = <0 11 RK_FUNC_GPIO &pcfg_pull_up>; }; }; ... }; This way u-boot is instructed to turn the power led GPIO active and the power hold GPIO (which is pin 11 of bank 0) active at boot. edit: I made some tests with other i2c buses, nothing did work, only i2c5 is able to retrieve a valid EDID to me

Thanks for the corrections to the device tree. I integrated most of them into the dts and I will publish them as soon as possible. At the moment I'm having problems compiling a working kernel because of some recent changes to the rockchip codebase which are producing non-booting kernels and I can't verify if everything is in place :/ I'm a little confused about the i2c5 bus, which is working pretty fine to me. I don't get any timeout message in dmesg and there shouldn't be any: all the rk3288 boards I viewed so far use the i2c5 bus for the HDMI DDC feature. Maybe you are having issues with your monitor due to some misconfiguration or malfunction of that? In which case I'm not sure changing i2c5 to i2c4 is a good idea for two reasons. The i2c4 bus currently hosts the rk1000 on some addresses, and also I think the DDC feature is hardwired to the i2c5 bus and we, in the device tree, are just informing the linux driver of that. Does it work changing i2c5 to i2c4 for you, or you just don't get the timeout messages? About the OTG cable, you should not use it anymore, I finally found the power hold GPIO which keeps the act8846 powering the board. Nonetheless I noticed the same behaviour you describe: reboot does not work but if I keep the OTG cable connected to the computer reboot works.

I'm developing this armbian fork for some rk3288 tv boxes. In my case audio via HDMI is working well in next kernel (4.14). I used the patched tinkerboard dts as "inspiration" for that part. I also had problems with audio until I bypassed these two lines: chroot $SDCARD /bin/bash -c "sed -i -e '/#load-module module-alsa-sink/r /usr/local/bin/pulseaudio.txt' /etc/pulse/default.pa >/dev/null 2>&1" chroot $SDCARD /bin/bash -c "rm /usr/local/bin/pulseaudio.txt" in build/config/sources/rockchip.conf for tinkerboard. You may take a look on github for that source code Also bluetooth is working fine (no hardware rfkill though), and I can happily stream audio from the phone to the monitor, but those tv boxes use broadcom-based AP6330 wifi SoCs.

Thanks pro, it would be really nice to have official support for these boards, they look pretty polished and really rock-solid to me and the SoC is quite amazing

This guide describes how to erase the internal eMMC memory. This won't brick your TV Box, instead will force it to boot from the SD Card. Also I give some steps to backup and restore the original firmware in case you want to restore the original functionality. The tool used here is rkdeveloptool, which is opensource and is available cloning or downloading the armbian rockchip-linux rkbin github repository mirror Get into rockusb mode: Getting into rockusb mode is essential to do anything else 1) plug the power cord inside the device 2) push the Reset button and keep it pushed while plugging the USB cable into the OTG port 3) check if the device is connected, use lsusb: lsusb Bus 001 Device 005: ID 058f:6377 Alcor Micro Corp.

Thank you! This is CSC Armbian for XT-Q8L-V10 boards, also known as Chiptrip Q8, Vsmart Q8, ENY 3288 Q8, etc... All source code has been merged into Armbian mainline project. I still keep my personal public Armbian fork for experimental features: https://github.com/paolosabatino/armbian-build Nightly images: download directory Quick installation instructions on eMMC: Build or download your preferred Armbian image from Download directory and a copy of the Multitool; Burn the Multitool on an SD card; once done, place the Armbian image in images folder of the SD card NTFS partition; Plug the SD card in the TV box and plug in the power cord. After some seconds the blue led starts blinking and the Multitool appears; OPTIONAL: you can do a backup of the existing firmware with "Backup flash" menu option; Choose "Burn image to flash" from the menu, then select the destination device (usually mmcblk2) and the image to burn; Wait for the process to complete, then choose "Shutdown" from main menu; Unplug the sd card, then push the power button for 1 second (the led will turn blue) After 10 seconds HDMI will turn on and you will get logging messages; On first boot you will be asked for entering a password for root user of your choice and the name and password for a regular user Run armbian-config to configure timezone, locales and other personal options Congratulations, Armbian is now installed! Boot from SD Card/USB stick (with Armbian already installed in eMMC, empty eMMC or no eMMC😞 Build or download your preferred Armbian image from Download directory; Burn the image on your SD card/USB stick; Plug the SD card/USB stick in the device; Push the power button for 1 second (the led will turn blue); After 10 seconds HDMI will turn on and you will get logging messages; On first boot you will be asked for entering a password for root user of your choice and the name and password for a regular user Run armbian-config to configure timezone, locales and other personal options Congratulations, Armbian is now installed! Boot from SD Card/USB stick (with original firmware or other firmware): In case your box has the original firmware installed, use the Multitool to erase the internal flash. Don't worry, you will not brick your box: once the eMMC is emptied, the box will automatically boot from SD Card. This is called Maskrom mode and is common to all Rockchip devices. Instructions and download links for the Multitool are at the bottom of this post. After erasing the internal eMMC, just follow the "Boot from SD Card" procedure above and then you are fine. Boot priority: Newer images (those with mainline kernel >= 4.14.50) now support booting from multiple devices. Priority is fixed and boot devices are probed in this order: External SD card External USB storage device (Any USB Stick/Hard drive attached to USB host ports) Internal eMMC This way even if you install armbian to internal eMMC, you can still easily test different images booting from external devices. Experts notes: when armbian is installed into eMMC you get U-boot installed too in eMMC. This is important to know because the box won't boot in Maskrom Mode, but instead will always boot the embedded U-boot, no matter if you put an sdcard/usb stick. In practice the embedded U-boot is totally responsible for the boot priority. If you want to restore the Maskrom Mode, just erase U-boot from eMMC using this command: dd if=/dev/zero of=/dev/mmcblk2 seek=64 count=8128 conv=sync,fsync Current status: Wireless: works. pretty fast and stable, signal is strong on my box; Bluetooth: works. I was able to transfer files and stream audio without problems USB ports: works, with autosuspend too. A quick benchmark show that transfer rate is quite good (topped at 34 MB/s) USB OTG: works in host mode. Transfer rate is very good (> 40 MB/s) MMC: works and is perfectly accessible as storage device. The images above with "eMMC friendly" have been tested and work when installed in eMMC using the standard armbian-config eMMC installer SDCard: works. legacy kernel is limited to high speed, while mainline works fine in UHS mode too. A quick benchmark with a Samsung EVO card shows the promised 48Mb/s read speed. Gigabit Ethernet: works, fast and reliably HDMI: works perfectly Serial: works Audio: both HDMI audio and SPDIF connector works IR remote: works on legacy and mainline kernels Reboot/Suspend process: rebooting the device is a working in progress, at the moment sometimes it works and sometimes it doesn't. Suspend is still not available. Hardware acceleration: everything which works for rk3288 boards applies here too. This guide or maybe the Media Testing Script will help you gain an hardware accelerated X11 and Chromium (using GL4ES I enjoyed Quake 2 from the start till the end, but also Quake and Quake III Arena work flawlessy, here a quick how-to to compile and install GL4ES) Multimedia: On mainline kernel 3D acceleration is provided by Panfrost driver and is already enabled.

Try to turn off and on the monitor. Once and then I have glitches with a pink column of pixels at the left border which, I guess, is something that should be fixed in hdmi drivers. By the way I tested the HDMI on a couple of devices, a Philips Monitor/TV and a Iiyama Monitor, both Full-HD and with in-built speakers and both works fine either with output and sound. For my understanding, rk1000 device drives only analog audio and video, so it not of any use on our TV boxes.

Sorry, that was my mistake. So I was too zealant in changing some regulators in order to support suspend features and so on and disabled the lcd power regulator Overwrite /boot/dtb/rk3288-q8.dtb with the rk3288-q8.dtb attached to this message and HDMI should finally work. I also provide the device tree source for reference, but copying the binary will suffice. rk3288-q8.dtb rk3288-q8.dts

@pro777 and anyone who is interested, I publish here the first draft of my work. Take this as a "proof of concept" for future work, this is nothing more than a test image. edit: see this page for better and more up-to-date armbian images The test image can be downloaded from here. It is an image of Armbian based upone latest 5.41 release for tinkerboard, with u-boot and kernel compiled using the device trees I adapted on the base of the original device tree coming from my tv box. A lot of work has already been done by other people. Current status: - Wireless, pretty fast and stable, signal is strong on my box; - Bluetooth, seems to work. I just tested a file transfer. - USB Host: works quite well but autosuspend is disable for the 4-port hub connected to this non-OTG SoC port due to issues. Transfer rate is quite good (topped at 34 MB/s) - USB OTG: works quite well in host mode, no quirks apparently. Transfer rate is very good (topped at 38 MB/s) - MMC: can be accessed, did not try to program it though - SDCard: works very well, in ultra high speed mode too. Tested a lousy class-4 sdcard and reached more than 60 MB/s! - Gigabit Ethernet: seems to work fast and reliably - HDMI: has some quirks, expecially if you attach and detach the devices. Generally works, but resolution is not configurable (see the note at the bottom) - Serial: works - Audio: HDMI audio works, but SPDIF is still a work in progress - IR remote: does not work, still trying to understand if a special driver is required or I am missing some pieces of the puzzle - Boot/Reboot/Suspend process: still some mysteries lays around here. The boot process on my box is a bit problematic (see the instructions below) and requires some attention. Suspend is not available at all. Rebooting the device via command line actually shuts it down. - Hardware acceleration: the kernel driver is there, userland drivers are still messy, but something can be achieved for the X server (see the link to the guide below) and probably the framebuffer GL ES driver works too Instructions: - First of all, you should boot your box in Maskrom Mode. One of the fastest ways is to zero-fill the internal MMC, I followed this as reference: https://github.com/nolange/rk3288-guide/blob/master/bootloader.md When in maskrom mode, the First Program Loader (which is the bootloader inside the SoC) will try to boot first from MMC chip, then SD card and finally USB. If you don't boot in maskrom mode, the SoC will always try to boot from the MMC chip, which has an obsolete u-boot - Flash the image over an microsd card, then plug the card into the box - If your box has a power button (mine has), push it and keep it pushed for some seconds, until you hopefully see the power led blinking. When the led is blinking, the kernel has started and your can stop pushing the power button. Note that if you push the power button for more than 10 seconds, the box will shut down. Another solution could be to connect the OTG port to your computer: doing this won't require you the keep the button pushed. - As usual, armbian default credentials are user: root password: 1234 You should be able to follow this guide to gain some hardware accelerated X server. It worked for me and I was able to obtain some pleasant Chrome experience. In /opt directory there are some firmwares and binaries downloaded from rockchip official github pages, and also the source device trees, scripts, and the configuration files I used to build the custom kernel and u-boot. I tried to stay stick to the default configs, so modifications should be minor. Also there is an enable_bt.h script to load the patch firmware and enable the bluetooh device. Kernel is 4.14, (current armbian mainline) and u-boot is 2018.3 (current mainline). I also tested latest 4.16 mainline kernel and rockchip pre-2018 u-boot, they also work. From the device tree, the CPU is configured to run at a maximum frequency of 1.6 Ghz and trigger the first thermal trip points at 70°C. A nice heatsink, or even a fan, are suggested. edit: for HDMI, I made a mistake. You will need to manually copy a new device tree binary into /boot/dtb directory. Look here for the dtb file

At the moment I have no published firmware yet. I would like to solve the boot problem soon if possibile, but I may think to share some preliminary work so who is interested can look into. I should really do some tidying up of the source device tree, kernel patches, binary firmwares and other things needed to make the thing work; I guess I can share my working image as a preliminary "demo" just for testing, sources may come as soon as possible

Great job! I'm working from the mainline side: kernel 4.16 and latest u-boot (2018-3) are working fine. I'm still facing a problem against the bootstrap and reboot (looking into the act8846 power regulator datasheet, see this), but most of the hardware is working very well, including gpu-accelerated chromium, wifi, bluetooth. I'm still missing the IR remote control.

Until someone put the bits for the DDR4 in mainline u-boot, you can use u-boot as a third program loader and extract the DDR4 memory initialization blob from the original image. I don't know if the booting procedure is the same as in rk3288 (I guess it is), but my rk3288 tv-box with DDR2 now boots mainline u-boot despite u-boot not supporting DDR2 initialization

Well, the rk3288 of the tinkerboard is still an out-of-order architecture, which has a better IPC (but it is also more power hungry) than the in-order architecture of the bcm2837 of the rpi3b+

I have some progress here and found some interesting things about. My TV-Box has LPDDR2 which is not officially supported by u-boot. U-boot supports only DDR3 and LPDDR3 rk3288 boards. There is a workaround although: I have to use the DDR SPL (Secondary Program Loader) binary supplied by Rockchip which does the RAM initialization. You can see the Rockchip binary at work looking to the log I posted above: the very first lines with the timings are the memory timings autodetected by the SPL. My tv-box comes with a binary which initializes the memory @200 MHz, but I found another binary which initializes the memory @400 MHz. I tried that to speedup the boot process. It worked and, surprise!, also I got more u-boot messages on the serial line showing a primordial bootstrap, but then the box suddenly turns off. Another discovery is that if I push and *keep pushing* the box power button, the boot procedure actually goes on for much longer and I get more messages, till the marvellous "Starting kernel"! Then the box powers off due to emergency shutdown happening when you keep the power button pushed too long.

OK Starting kernel ... The problem is that probably there is some sort of timer or watchdog which turns the box after a specific timeout, and that timer is not counting while I keep pushing the power button. I may guess that it can be a GPIO that should be turned off or on, but I really don't know which one could be. I gladly accept any experience or hint about this behaviour

Ok, I did some research, trial and errors, a lot of time lost around this issue. At last, I found that setting the autosuspend property for the USB host to a large number doesn't immediately kill the dwc2 USB host port, so this is definitely an autosuspend problem, which led me back to the mailing list thread I linked above. The most recent post of that I can find is this: https://patchwork.kernel.org/patch/9469811/ The patch is not yet in upstream kernel, so I patched it manually and adding the proper reset lines to usbphy2 section this post I finally made it work! The working device tree is attached to this post, along with a dmesg for the most curious. Anyway the author of the patch says that this is a "workaround", because RK3288 has an errata about the dwc2 host post messing around with the usb bus when it is reset. There is some tuning to gain performance and reduce cpu usage, which is definitely too high at the moment. rk3288-q8.dts dmesg.log

Swapped the device tree with the MiQi, the box didn't boot at all, crashing in the middle of the kernel boot :/ The missing regulators should not be a real problem, at least I think I saw them on some other kernel logs from tinkerboard bootstrap. Reverted back the usb_host0_ehci and usb_host1 sections to status = "okay" only, but no luck either. I'll do some more research, and post here the findings

Hello Myy, I guess you're behind the kernel work. First of all, thank you! Attached to this post there is the output of lsusb -v and lsusb -t before attaching the USB device and the output of dmesg after the USB stick is attached. There is a 4-port hub soldered on the board after the SoC USB port, it is controlling the two exposed USB ports. If I boot the system with the USB stick attached it is correctly detected and works too. As long as I leave at least one device attached I can connect and disconnect other devices. All of them get properly detected and work. When I unpopulate all the ports I can't connect any USB device anymore because I get the USB reset and read errors you can see in dmesg log. If I plug an USB device after the system boot I get the reset/read errors and the USB ports stop responding. Also the 4 port hub disappears from the list of USB devices. The mailing list thread describes a very similar problem but the proposed solutions (autosuspend, reset pins in device tree) seem not to work in my case. PS: I compared the original device tree and the one I'm using which is a rework by DengueTim based on the firefly device tree. I attach it also to this post in case you want to take a look into. I tinkered a bit with it: enabled the apparently unused generic-ehci usb host @ff500000, added some resets... but I'm not a master in there and I'm still trying to realize how device trees work. dmesg.log lsusb.before.log lsusb-t.before.log rk3288-q8.dts

Hello, back again on the topic. I studied for quite some time this q8l, found a lot of interesting things about and now I'm able to boot a pretty stable Linux mainline kernel with a minimal but totally functional debian stretch. Linux kernel has been built using the scripts from RockMyy (https://github.com/Miouyouyou/RockMyy). Unfortunately there is an issue with the USB ports which is preventing me from publish a working image. I found some info about the very same issue in this mailing list thread: the guy suggests that patching the dts file solved his problem, but it didn't work for me. If someone is interested or has an idea on how to solve I could pack the things up and share this preliminary work.

Every time I reboot the machine, it stops inside the tree evaluation, but always in a different part.

I'm spending some time on one of those famous Q8 tv boxes (ENY Q8, VSmart Q8, etc...) which sports the rk3288 soc I started with recent u-boot and kernel releases. Rockchip provides a recent u-boot (late 2017) and an LTS 4.4 kernel on their rockchip-linux github account. I compiled u-boot (from here) using a the device tree source from DengueTim (available here, in arch/arm/boot/dts/rk3288-q8.dts). I had to enable the serial driver though, because the device tree is "kernel flavour", instead u-boot wanted explicitly the serial port in "chosen" section. Compilation goes fine and u-boot boots from the SD card, prints Model, Ram and MMC infos on the serial and then stops. Pushing the power button of the TV Box restarts the boot process, so the box is not frozen, but it is more like being shat down. I also tried different board configuration and device trees (firefly, tinkerboard), and I discovered that u-boot behaves exactly the same, printing the same info lines (albeit Model being incorrect) and then stops. Now I'm stuck because I don't understand if there is a fault in the device tree or in u-boot .config file. Any experiences or hints are greatly appreciated (I'll post logs as soon as I can)

Hello anyone, I managed to pack a basic system for my Q8 tv box which seems to be *really* working. It is a very basic debian wheezy running on the stock 3.10.0 kernel, no framebuffer console, and misses a lot of things, but it is a start point for anyone who wants to experiment with this tv box. The goal is to achieve armbian running on a fairly recent kernel! Here you can download the archive, which contains the basic image parts and a bash script to flash them onto an sd card. The system is a bare minimal debian wheezy which asks a DHCP server for an IP and spawns SSH daemon. Check the included readme.txt file for more detailed infos. Have fun!

Hi hoskit, yes I was able to get the job done. I suggest you to take the very latest development armbian nightly which already has the HDMI bits in the device tree, just not to tinker about the kernel compilation and other messy things. The guy (mripard) on github fixed some regression he introduced that broke the mali kernel driver compilation on slightly older kernel, so now compilation and installation should be pretty accessible. I tried only the framebuffer version, and yes, it was working pretty well: I tried different OpenGLES2 demos from the official Mali SDK and they all worked without issues

There is no pci bus in these SoCs, you should use lsmod to see if there is any module related to wifi and iwconfig to show the network interfaces which support wifi
