Ok...so the verdict is I have a bad TTL adapter. I have a Rock64 and some jumper wires, and the Rock64 has a UART on it capable of running a 1500000 baud...so I wired up the debug pins on the OPi to the UART on the Rock64 -- and bam, I get stuff that I can at least read. (The only bad thing is that the Rock64 leaks voltage out of the UART pins...so the board tries to power on as soon as you hook it up.) Without the SD card? I think you're right -- it tries to boot into Android. I see a bunch of messages from the kernel, and then it drops into a shell. (Interestingly, it also spits out a bunch of errors b/c the filesystem is read-only...but whatever.) With the SD card? Here's what I get: �DDR Version 1.14 20180803 In Channel 0: LPDDR4,50MHz CS = 0 MR0=0x18 MR4=0x1 MR5=0x1 MR8=0x8 MR12=0x4D MR14=0x4D MR18=0x0 MR19=0x0 MR24=0x8 MR25=0x0 CS = 1 MR0=0x18 MR4=0x1 MR5=0x1 MR14=0x4D MR18=0x0 MR19=0x0 MR24=0x8 MR25=0x0 Bus Width=32 Col=10 Bank=8 Row=15/15 CS=2 Die Bus-Width=16 Size= LPDDR4,50MHz CS = 0 MR0=0x18 MR4=0x1 MR5=0x1 MR8=0x8 MR12=0x4D MR14=0x4D MR18=0x0 MR19=0x0 MR24=0x8 MR25=0x0 CSMR4=0x1 MR5=0x1 MR8=0x8 MR12=0x4D MR14=0x4D MR18=0x0 MR19=0x0 MR24=0x8 MR25=0x0 Bus Width=32 Col=10 Bank=8 Row=15/1S=2 Die Bus-Width=16 Size=2048MB 256B stride channel 0 CS = 0 MR0=0x18 MR4=0x1 MR5=0x1 MR8=0x8 MR12=0x7MR19=0x0 MR24=0x8 MR25=0x0 CS = 1 MR0=0x18 MR4=0x1 MR5=0x1 MR8=0x8 MR12=0x72 MR14=0x72 MR18=channel 1 CS = 0 MR0=0x18 MR4=0x1 MR5=0x1 MR8=0x8 MR12=0x7R19=0x0 MR24=0x8 MR25=0x0 CS = 1 MR0=0x18 MR4=0x1 MR5=0x1 MR8=0x8 MR12=0x72 MR14=0x72 MR18=0x0 MR 0 training pass! channel 1 training pass! change freq to 400MHz 0,1 channel 0 CS = 0 MR0=0x18 MR4=0x1 MR5=0x1 MR8=0x8 MR12=0x72 MR14=0x72 MR18=0x0 MR19=0x0 25=0x0 CS = 1 MR0=0x18 MR4=0x1 MR5=0x1 MR8=0x8 MR12=0x72 MR14=0x72 MR18=0x0 MR19=0x0 MR24=0x8 MR25=0x0 channel 1 CS = 0 MR0=0x18 MR4=0x1 MR5=0x1 MR8=0x8 MR12=0x72 MR14=0x72 MR18=0x0 MR19=0x0 MR0=0x18 MR4=0x1 MR5=0x1 MR8=0x8 MR12=0x72 MR14=0x72 MR18=0x0 MR19=0x0 MR24=0x8 MR25=0x0 channel 0 training pass! channel change freq to 800MHz 1,0 ch 0 ddrconfig = 0x101, ddrsize = 0x2020 ch 1 ddrconfig = 0x101, ddrsize = 0x2020 pmugrf_os_reg[2] = Boot1: 2018-08-06, version: 1.15 CPUId = 0x0 ChipType = 0x10, SdmmcInit=2 0 BootCapSize=100000 UserCapSize=14910MB FwPartOfmmc0:cmd5,20 SdmmcInit=0 0 BootCapSize=0 UserCapSize=15193MB FwPartOffset=2000 , 0 StorageInit ok = 182421 SecureMode = 0 SecureInit read PBA: 0x4 SecureInit read PBA: 0x404 SecureInit read PBA: 0x804 SecureInit read PBA: 0xc04 SecureInit read PBA: 0x1004 SecureInit read PBA: 0x1404 SecureInit read PBA: 0x1804 SecureInit read PBA: 0x1c04 SecureInit ret = 0, SecureMode = 0 GPT 0x3190d20 signature is wrong LoadTrust Addr:0x4000 No find bl30.bin No find bl32.bin Load uboot, ReadLba = 2000 Load OK, addr=0x200000, size=0xa69c4 RunBL31 0x10000 NOTICE: BL31: v1.3(debug):f947c7e NOTICE: BL31: Built : 20:19 BTW -- I didn't have to connect TP50625 to anything to get it to boot off the SD card.

Also, if you are going to use the board for LUKS encrypted storage, you may want to have good disk IO performance. So you should probably aim for something with USB3 or PCI support. Rock64 seems like a good option to me, if you want something affordable.

Many thanks for your response. I just don't understand why. With my old system stretch-openmediavault-rock64-0.9.14-1159-armhf.img everything worked without problems. Now I have determined: after about 30min to 1st hour I can quite normally use hostname on e.g. Access OMV GUI. That is very confusing.

Hi guys, I was wondering whether the image for, e.g., the Rock64 can be expected to work also on a TV-Box with RK3328 chipset, for example this one? Cheers, chessplayer

Sorry for the long delay ... I used the Espressobin and Rock64 pro. With my espressobin I noticed the extra material in the slot was stressing the connector. I ended up going with another carrier board like this - https://www.amazon.com/gp/product/B07T7NJZTY/ref=ppx_yo_dt_b_asin_title_o07_s01?ie=UTF8&psc=1 I tried several kinds, the ones with the little flip SIM card holder held the sim card more consistently. The little snap in types kept snapping out. Some have minute sizing differences, one fit perfectly on the espressobin, some wouldn't clip in. I really dug that little sim card adapter at first, but it ends up being a real pain if you do anything but put it in and leave it.

I have a 4G Rev 2 Rock64 that is running like a champ on current - 5.4.2 as of this writing, as far as USB and Ethernet are concerned. I did have to blacklist UAS for all my USB drives, and now the board is rock solid even with heavy disk and network IO. I do have one problem though, I have no sound. I have the following loaded (automatically): root@chdock:/home/sugata# cat /proc/modules |grep snd snd_soc_rk3328 16384 0 - Live 0xffff800008dc9000 And yet, I get this: root@chdock:/home/sugata# aplay -l aplay: device_list:272: no soundcards found... I searched around this forum and nothing obvious came up. Any ideas?

Same here, after updating to the 5.3.11 kernel my Rock64 4GB rev2 doesn't come up from the SD. I have a USB SATA-SSD, but no HDMI attached. The 4.4 kernel works perfectly fine, so I reverted back to that one. I guess we'll have to wait some time for the current branch to become fully stable.

After 2 boot crash restarts my Rock64 4GB rev2 on Micro SD has come up on 5.3.11 kernel. rock64:~$ uname -a Linux rock64 5.3.11-rockchip64 #19.11.3 SMP PREEMPT Mon Nov 18 21:03:09 CET 2019 aarch64 GNU/Linux It looks like the first two times `pstate: 60000085` then on the 3rd time: `pstate: 20000005`. 3rd time still has stack trace related to zstd but otherwise makes it through. I have USB SATA-SSD (Pine store), eMMC (pine store) cards and another 6 Rock64's if there is anything I can do/provide. I'm tempted to try load up Kubernetes on them all with this image and see how stable it is. Okay, it lasted about 5 minutes. Has a Pine store heatsink. Failed during apt upgrade (download fast 1Gbps) but nothing after that. Have switched to a 30A 5V supply running 5V (multimeter) just in case the Pine store PSU is too weak but haven't been able to get it to boot again. ArchlinuxARM has come up on first boot with 5.3.1 and crashed after a few minutes.

Thanks for fixing this! I couldn't do umlauts on my Rock64 via ssh. The internet suggested editing etc/inputrc, but I figured this couldn't be the root of the problem. So have been a little lost here for a while. --- food for search engine: (arg: 6)

If you follow the link I posted above, you will see at the status matrix that, indeed, encoding is not yet implemented. It has the most standard and easy to implement and use interface, v4l2-m2m XU4, MC1 and HC1 are sold now for less than $50, which I consider cheap considering its power, features and stability. Take into consideration that one of these can do the work of four to six H3 boards, for example. And if you want to build a farm, you can stack several HC1 or MC1, and put a fan on them, which will make them run steadily at maximum frequency. If you still want something cheaper with HW encoding, then you can go for a 1Gb Rock64, but these boards are having lots of stability problems lately.

Hello, this was my way to make RTC DS3231 works on rock64. apt-get install i2c-tools - /etc/rc.local /lib/udev/hwclock-set /dev/rtc1 exit 0 - /lib/udev/hwclock-set if [ -e /run/systemd/system ] ; then # exit 0 /bin/enable_dtoverlay i2c0 i2c@ff150000 okay echo ds1307 0x68 > /sys/class/i2c-adapter/i2c-0/new_device fi #if [ -e /run/udev/hwclock-set ]; then # exit 0 #fi HCTOSYS_DEVICE=rtc1 Copy to /bin/ and make executable https://raw.githubusercontent.com/ayufan-rock64/linux-package/master/root/usr/local/sbin/enable_dtoverlay systemctl stop systemd-timesyncd.service systemctl disable systemd-timesyncd.service systemctl stop fake-hwclock.service systemctl disable fake-hwclock.service sudo apt-get -y remove fake-hwclock apt install chrony

Hi all, and thanks for this great install script! I've been using a Raspberry Pi 3 as my main video player for a while and I recently switched to a Rock64. After installing the required dependencies with the media script and using mpv-gbm for playback, I noticed that the video playback was choppy and mpv would drop frames, even for "small" (i.e. non-4k) videos. I tracked down the problem to the display mode not being set right by mpv: whatever the video format, my display would be set to 3840x2160p60 (as seen from /var/log/kern.log). After manually setting the right display mode, the video playback is perfectly smooth and there are no more frame drops. For example: mpv-gbm --drm-mode=25 bbb_sunflower_1080p_30fps_normal.mp4 mpv-gbm --drm-mode=19 bbb_sunflower_1080p_60fps_normal.mp4 You can get a list of the DRM display modes with: cat /sys/class/drm/card0-HDMI-A-1/modes | nl -v 0 As a side note, I have not been able to play 2160p content at more than 15 fps and trying to play 2160p60 content even resulted in a corrupt display (green bands and pieces of picture jumping around). Thanks again!

Sigh, no change using /dev/mmcblk1p2.

Well, firstly don't overwrite your u-boot sectors with a fat partition. Nothing works. Secondly: rootdev=/dev/mmcblk0p2 isn't it either.

It would be interesting to try the new kernel 5.x . If the hardware that is responsible for the work of eMMC is all right and the device works stably from the SD card, then the problem is in the settings for eMMC and need to check the settings of DTB to work with eMMC or u-boot. P.S. I don't have Rock64, so all of the above is just a guess. On TV boxes with rk3328 and the built-in eMMC at me everything works without problems from eMMC.

Hello, I've the Rock64 4G v2.0 - 2017-0713. I tried to install different OS but I get similar errors and problems as yours. The SBC stuck after a while or lost the connection after high I/O traffic with my SSD on the USB3. If It can help you, I describe here how I could installed a clean Armbian on my rock64: - Download u-boot-flash-spi-rock64.img.xz from here and use Etcher to write to a new micro SD card; I used SanDisk Ultra 16GB microSDHC, Class 10. - Download OS image “Armbian 5.69 Ubuntu Bionic default, Kernel 4.4.167” from the archive here and use Etcher to write to the SSD. - I both a new power supply because I get some under voltage errors. But I still have to measure the differences. I've got this by amazon. - Insert the SD card into Rock64 and boot it. It will automatically flash the SPI memory. Wait until the white LED on Rock64 blink once per second. Wait for some more time just to ensure the writing is done and then remove the SD card and power off the board. - Connect network cable to Rock64 and attach the SSD to USB 3.0 port and then boot Rock64. Log in only with HDMI monitor and Keyboard and change the pw and user name. - Connect the SSD to another linux and check and repair the partition (job 1) and extend it till the end (job 2). - Re-connect the SSD and go to armbian-config and then freeze the Kernel and File System. Check desmeg results. Try also to connect with ssh. I get now a clean and stable board and I´m happy after many month trials. If I can help someone would be nice. Let me know.

So, I'm out of ideas now. I have done all of the above, in-fact mounted the whole filesystem (eg. /root) as RO so definitely there are no writes happening on the EMMC card (double checking with iostat -dzp 1). And _still_ the board crashes! This is debian Buster with Armbian 5.98 Linux 4.4.192-rockchip64.

The machine stayed up but something was hogging the CPU so much it was unusable and I had to reboot. I've moved the HDD to the USB2 port and I just had a crazy kernel panic and the board rebooted by itself. I did get _one_ step further. Remember when I said the board was stable previously? It was with the sd-card in it, not the emmc. It also seems that the board is more stable with the serial cable plugged in. I will double check, but it would seem that even in RO mode running the OS off of the EMMC is batshit unstable. Anyone experienced this and might have ideas to resolve it?

serial terminal this unit was booting fine one day and then not the next. it will boot to the serial terminal but not far enough for ssh or even a functional ethernet. this is running on a rock64 w/16GB eMMC. nothing else is really unique about it.

If it's any consolation... I have 7 Rock64 v2. 3x emmc, 3x USB2 SSD, 1x sd card. All from pine store. Bought and wired up 30A 5v DC power supply but haven't tested. One of the emmc is dead. One of the boards crash loops no matter what drive. None of them run usb3 reliably. Archlinux was newest most reliable kernel around 4.19 or 20. Haven't been able to get above 4.4 otherwise and wanted to use Ubuntu for home cluster so Arch out. Plus wanted over 4.9 for Linux network functionality. Put a bit of money into this setup. Naive. RPI not enough memory and new ones expensive. Given up and gone back to amd64 VM's.

I am quite upset. Reading around more it looks like the FORESEE emmc cards sold on the rock64 shop are utter crap. The only reason I bought them from their shop because I trusted them to deliver good quality components with the board. Teaches me right. I contacted support about the card, they waived me off with "you only have 30 days guarantee, but anyways you should limit the number of writes to the card as otherwise you can kill it within a week". Thanks for that. I've read around a bit more and my last hope is a few more tweaks before I give up and just buy a raspberry pi. 1. Lower the emmc clock frequency to 150MHz from 200MHz as it seems many cards/boards cannot take the higher frequency. You do this through "echo 150000000 > /sys/kernel/debug/mmc0/clock". See here https://forum.pine64.org/showthread.php?tid=5258&pid=39964#pid39964 2. As many problems seem to be around usb3 people suggest to disable the uas driver. See here https://forum.pine64.org/showthread.php?tid=5137&pid=32107#pid32107 3. Mount whatever I can on a tmpfs and other options, see here for tips https://raspberrypi.stackexchange.com/questions/169/how-can-i-extend-the-life-of-my-sd-card 4. Try and use the HDD on the usb2 port and get a usb power splitter After this I'm out of ideas. Sent from my Mi A2 using Tapatalk

On my Rock64 v1.1, I have no issue with USB, they are present. I'm using self-made build 5.4.0-rc1 stretch...

Okay, I tried Armbian_5.99.191031_Rock64_Debian_buster_dev_5.3.0-rc4_minimal.img on my ROCK64 4GB v2.0 It booted fine to the point I could SSH into it. dmesg said it timed out waiting for /dev/ttyFIQ0 all USB2 and USB3 ports were not working did apt update && apt upgrade and it hang power cycled it. it responds to ping with ~28% packet loss but does not answer to SSH. Back on the shelf to collect dust for another month

Well, the specs of rock64 looks good, until you use it to do some actual work... It even can't survive make -j 4 for aria2
