Q8 boards are those with "Q8" in the name. Mine is a xt-q8l-v10, but there are others like eny-q8l-v10 and so on... all of them are pretty similar in the board design. Yours has a different signature, R36 you say, and in fact it is somehow different from q8 boards. All the boards have the rockchip rk3288 SoC, but as I said in the post of the other thread, some differences may be so important that some hardware may not work (wifi is one of the best candidates), or even don't the let kernel or the board boot at all. It happens 🤷‍♂️ The error message is not really an error message. That file does not exists and should not exist, therefore I don't see any other message: it looks like u-boot got stuck there because I don't see the usual messages about mmc/sdcard probing for the kernel. Are you sure it does not progress further? Anyway, you can even try to burn armbian on the sdcard and let it boot from there to see if it works or not; of course if multitool does not boot probably armbian neither will, but surely worth a try. As last resort, you can restore the original firmware using rkdeveloptool (and just that one, not other tools) following these instructions; just be sure to unpack the backup before running rkdeveloptool wl command No, the board is not recognized as Q8. The board can't be recognized in any way from the software; instead u-boot is configured to use a stripped-down version of the device tree originally made for xt-q8l-v10. It should be generic enough to run on more rk3288 boards. If you're questioning yourself about the device tree, it is a file that contains the specs of the board hardware. Maybe you heard about ACPI/Plug and Play on x86 world, so the specs of the hardware are supplied by the BIOS to the operating system; in the ARM world there is no such thing like BIOS and ACPI, except on some server hardware. The specs of the hardware are described in a static and handwritten file given to u-boot and linux kernel, so they can know what is the hardware they have to deal with.

Hello, I noticed the message on the Q8 thread yesterday and noticed this other thread here right now... one baby step after another I gave you some general hints on that thread (this post), but I guess it is more appropriate to keep the conversation here. From what I see from your logs, you installled something on the board which is a legacy android, if I understand correctly you still have the backup you took with the multitool and now you have this other rikomagic firmware installed which is not really working on the box. The backup took with multitool is just a raw gzipped imaged of the internal flash, I wonder what you intended with "the image was not recognized"; by whom? If the multitool is not able to recognize the backup image produced by itself probably the sdcard is faulty and the backup data is broken. Multitool should allow you to backup as well restore the backed up image. Surely if you want to use the backup in AndroidTool for windows or rkdeveloptool for linux you first need to unpack (I'm not even sure AndroidTool is capable to write a raw image). In the other post I mention to use maskrom mode to exclude eMMC and be able to use rkdeveloptool with USB male-to-male cable: rkdeveloptool can be used either to flash directly the backup image or erase the flash and let multitool boot again and flash image with it. Since the board is booting, it is possible that the multitool boots when you put in the sdcard and give power, but as long as the firmware you installed on the eMMC is not the original one it may not be true anymore.

@Mierscheid sorry for the late reply, but I didn't notice the post. The image you installed is for another board called xt-q8l-v10, which is based on rk3288 but surely not the same board. This is quite important, because each board, especially "high-end" boards like this, have their own design and usually have a different Power Management Integrated Chip (PMIC). This is important because this little chip drives all the currents of the board, and if it is not configured right won't allow the board to work the right way. There may be other differences that may break things, so it is not advisable in general to burn an image directly on the eMMC without carefully testing it via sdcard first. The board can surely be restored to working state, but without UART logs is impossible to even guess where is the problem; surely bringing the board into maskrom mode (see this post) will allow you to use rkdeveloptool to erase internal flash and force the board to boot from sdcard (either multitool or directly an armbian image). I guess you already tried to boot the multitool from sdcard without success, this makes me think that the u-boot installed on eMMC has issues or does not even boot, which is bad enough to guess you need to bring the board into maskrom mode and do a manual intervention. The maskrom mode link I posted above is for rk322x, but actually it works exactly the same because eMMC chips have all the same pin layout. Once you keep the short the emmc clock pin to ground, you are "clock gating" the emmc and in practice it excludes it from the system just like there is no eMMC at all. When you unshort the pins, the eMMC will start working again.

Interesting you found a way to put the device in maskrom mode, the testing points are not always obvious. I will link this thread in the rk3318 first post for future reference. However once in maskrom mode the board will boot from sdcard. As far as I remember, yours has the sdcard allocated to a "secondary" controller and for this reason probably is unable to boot multitool from sdcard when in maskrom mode. You could use rkdeveloptool to erase or program the internal flash manually when in maskrom mode with linux, or use the AndroidTool with Windows

@Buqan Kaleng Kaleng seriously, I really don't understand what you're talking about. 🤷‍♂️ You said you can run multitool from sdcard, then erase the eMMC from multitool if you want to zero-fill the eMMC and zap anything. If you can't, the emmc is not detected and thus probably broken. There is no bootloader involved in hardware detection. From armbian you can run blkdiscard /dev/mmcblk2 to do the same the multitool does. Again: any error here means the emmc is not detected and probably broken.

@Buqan Kaleng Kaleng I don't what you are talking about... if the multitool does not see the emmc, maybe it is just broken.

@mkultra yes, you can now unhold the packages

Looking at kernel dmesg I think it definitely has a problem: Sep 07 18:56:18 rk322x-box kernel: mmcblk0: error -110 transferring data, sector 520, nr 504, cmd response 0x900, card status 0x0

@Krotosz6 Good you discovered it by yourself current and edge are kernel flavours. Current is the stable one, which is older but expected to always work. At the moment the current kernel is 5.15. Edge kernels are experimental/development. They are newer (at the moment 5.19) but can break anytime because they are not guaranteed to work, since they are... experimental! I don't have anything against tutorials, they are welcome, but the problem with them is that they become obsolete. In fact the apt-mark step is not necessary anymore, since support for rk3318 is now part of mainline armbian. The best tutorial is described in the first page of this thread, plus it is always kept up to date. Also images are now compiled and signed by armbian servers too, not anymore by myself - full instructions are again in the first post.

@Krotosz6 Hello, indeed you're not seeing the internal memory: as long as the two pins are shorted, the clock of the internal flash is gated to ground: basically it does not receive any clock and that's the reason it is bypassed. You should short the two pins, turn the board on and then release the pins almost immediately. So far, even if the image installation has been interrupted, multitool should be able to boot anyway unless you wrote an image for another similar soc or you interrupted it so soon it was not able to write the bootloader. By the way, once armbian has booted, you should be able to see the internal flash as /dev/mmcblk2, thus blkdiscard /dev/mmcblk2 or dd if=/dev/zero of=/dev/mmcblk2 bs=1M count=32 oflag=direct should both be able to clean the existing bootloader on internal flash to let it boot again; otherwise you can use the multitool to do the same.

@fukowaka You did not need to burn them on eMMC to test the mainline kernel images. Once armbian (any version) is installed on internal eMMC, it enables full boot from sdcard and USB stick too, so it is sufficient to burn the image to test directly on sdcard and plug the sdcard in the slot. Anyway you can increase the boot logging level changing verbosity=1 to verbosity=7 in /boot/armbianEnv.txt; this way the kernel w ill log much more informations and maybe will tell something intersting about the issue. Also you may add cpu-stability to overlays= line in /boot/armbianEnv.txt to see if the board boots. Also i have a question: do the mainline kernel images never boot, or they refuse to boot after you run rk322x-config?

@Eliel Prado Taking a look at the log, it looks to me that your board freezes exactly after 60 seconds of operativity. it is highly suspicious, this kind of behaviour was often found when a wrong Trust OS (TEE) was in use, causing some kind of watchdog to trigger after a predetermined amount of time resetting or freezing the machine. The few garbage bytes on the serial just before rebooting were also typical about the Trust reboot thing. What is way more interesting is that the trust in use has been widely tested with a lot of boards and seems to work fine, but as long as it is proprietary binary code we don't know what does it do. I could provide you a special image with an opensource Trust and see if it works, but you have to wait a week or so for that (I'm on vacation right now...) Also it looks to me that you're using an outdated version of multitool, please try with latest version.

@Neil WolfkidHello! You're a bit out of luck: if you want to use the legacy kernel builds you need to install the multimedia framework, which is unmaintained anymore and probably won't work on latest ubuntu versions (it was conceived for Focal). Mainline kernel builds instead have out-of-the-box support for 3D acceleration via Lima driver, and also hardware video decoding is supported in hardware (but in this case you may need specially crafted software - in few words: it does not work yet out of the box). In case you use mainline builds, you lose access to internal NAND: an experimental driver was brought up, but it happened it was not working as it was meant to.

This makes me think you have some fake specs: rk322x cannot address more than 2GB of RAM and 4GB NANDs are pretty uncommon - never seen any rk322x with that amount of flash memory. Looking at the log dump I see 1Gb of RAM for your board. Anyway I don't understand why you are such an old image from 2020...

@fukowaka glad to hear your board works fine. I suggest you to use a mainline kernel if you don't have a NAND, the kernel is way more up to date. Legacy kernel builds are very old and I just keep them for people with NAND boards. The eMMC tuning options (which obviously applies only to boards with eMMC/eMCP and not NAND) can give a consistent boost to eMMC throughput, but your mileage may vary.

@Seth Your issue is due to the low pin strength used for GPIO, in some earlier tests I found that lower pin strength for wifi increased overall stability so it is set that way by default, but probably the stability issues were caused by something else. I should set them back to default values. Anyway you should tell what is the real board in your scishion v88 box, as far as I remember, there were some chiptrip mx4vr or something like that into...

armbian does not boot from sdcard with Android bootloader. It will boot from sdcard once it is installed in emmc, so you can test other armbian images from sdcard without overwriting emmc.

Four or five posts above there is the answer: https://forum.armbian.com/topic/17597-csc-armbian-for-rk3318rk3328-tv-box-boards/?do=findComment&comment=146012

Looking at the USB vendor and device IDs, your chip is not a rk3228a but an rk3128. You may say "But the chip is labelled rk3228a!": there have been past evidences that labels on the chip have been manipulated; I remember a case of a user were the chip was an rk3228a but the label was "Amlogic S905W". rk3128 in different unsupported chip.

LIRC comes after the kernel-based handler. You should investigate ir-keytable instead, that will change the kernel-level key bindings for the remote.

If you run echo b > /proc/sysrq-trigger from root does the board reboot or turns off?

The multitool should boot in every case, don't know the reason why it does not boot 🤷‍♂️

I have no tv boxes with rk3328; also the marketing name does not really mean what is the board inside. If you have such a board you can try and select led-conf3 in rk3318-config which currently is the most suitable for rk3328 boards

@Willy Moto I had time to check the apt issue about being slow... it definitely too slow when it generates the dependencies tree, so a get a bit deep into. In my case I solved going into /etc/apt/sources.conf.d, renaming of any repository (I suggest box64.conf or nala.conf) with suffix .disabled, run apt update, then enabling back the repository and running again apt update. Now the dependencies tree is built in a blink of an eye.

Well, I may guess there is a problem somewhere else. It could be an issue with the sdcard/emmc or a power issue (does openssl speed -multi 6 rsa turn off the board?), because the unresponsive system - not being able to ssh in - means not only the monitor blanks, but the board turns off or freezes. The board should also have a blinking led by default, does the led stop blinking when the system is unresponsive?
