  1. crosser@kobol:~$ uname -a Linux kobol 5.10.60-rockchip64 #21.08.1 SMP PREEMPT Wed Aug 25 18:56:55 UTC 2021 aarch64 aarch64 aarch64 GNU/Linux crosser@kobol:~$ cat /etc/os-release NAME="Ubuntu" VERSION="20.04.3 LTS (Focal Fossa)" ID=ubuntu ID_LIKE=debian PRETTY_NAME="Armbian 21.08.1 Focal" Cannot really "elaborate" what I am doing with NFS, I just use it lol! There was no special excessive data transfer at the time, to the best of my knowledge. And it was just one such occurrence so far, since I am using the device. It's not a problem for me (so far at least), I simply thought that it would be right to report.
  2. Make it easier to disconnect fans, so the back plane is not hanging on the wires when disassembling.
  3. This happened out of the blue, without indication of anything else being wrong. I just noticed that NFS stalled, and realized that the server is not on the network. The system on the box was running fine, but there were no lights on the network connector (it is connected with the upper, 1Gb, adapter). I replugged the cable into the 2.5G socket and it went online. Then I powered the box off and on again, with the cable in the 1G socket, and it came online normally. This is what I found in dmesg/syslog: Aug 31 09:31:39 localhost kernel: [379809.423687] NETDEV WATCHDOG: eth0 (rk_gmac-dwmac): transmit queue 0 timed out Aug 31 09:31:39 localhost kernel: [379809.424506] WARNING: CPU: 2 PID: 0 at net/sched/sch_generic.c:468 dev_watchdog+0x398/0x3a0 [...] Aug 31 09:31:39 localhost kernel: [379809.447941] rk_gmac-dwmac fe300000.ethernet eth0: Reset adapter.

  4. Whether it is a coincidence, newer kernel after one of recent updates, or changed timing due to increased verbosity, but the system comes up all right after `reboot` command last few times. Knocking on wood. And thank you in any case!
  5. I have armbian focal installed in mmc, kernel 5.10.16-rockchip64. After `reboot` command, boot never completes (no heatbeat LED, no network access), though boot process seem to go quite far: [ 10.832087] rk_gmac-dwmac fe300000.ethernet: TX Checksum insertion supported [ 10.832732] rk_gmac-dwmac fe300000.ethernet: Wake-Up On Lan supported [ 10.833507] rk_gmac-dwmac fe300000.ethernet: Normal descriptors [ 10.834059] rk_gmac-dwmac fe300000.ethernet: Ring mode enabled [ 10.834594] rk_gmac-dwmac fe300000.ethernet: Enable RX Mitigation via HW Watchdog Timer [ 10.843920] rockchip-vop ff8f0000.vop: Adding to iommu group 2 [ 10.847541] rockchip-vop ff900000.vop: Adding to iommu group 3 [ 10.973820] libphy: stmmac: probed [ 10.974169] RTL8211F Gigabit Ethernet stmmac-0:00: attached PHY driver [RTL8211F Gigabit Ethernet] (mii_bus:phy_addr=stmmac-0:00, irq=POLL) [ 10.975287] RTL8211F Gigabit Ethernet stmmac-0:01: attached PHY driver [RTL8211F Gigabit Ethernet] (mii_bus:phy_addr=stmmac-0:01, irq=POLL) [ 11.294450] async_tx: api initialized (async) [ 11.450714] BTRFS: device label export devid 3 transid 224560 /dev/sdb1 scanned by btrfs (353) [ 11.452467] BTRFS: device label export devid 2 transid 224560 /dev/sda1 scanned by btrfs (353) [ 33.760041] vcc3v0_sd: disabling [ 33.760359] vcc5v0_typec: disabling [ 42.900266] random: crng init done After reset button, boot sometimes completes, sometimes not. After power cycle, boot always completes. Should I, too, contact support? And what is "armbian overlay"?
  6. Thanks! I could not respond earlier because forum allows to make only one post in the first day. It is embarrassing, I am actually quite certain that I tried to boot with SD card and without it several times, and the result was the same (no signs of life). And I even wrote the image to the card again and tried again. But when I tried to boot yet again with the same card the next day, after reading @SIGSEGV's answer, it booted! I can only suspect lousy contact on the card or something?.. @gprovost yes, of course I did. And believe that I explained clear enough at "which step". Anyway all is well now, thank you for your help!
  7. I got my box yesterday and assembled it (looks gorgeous, and reasonably easy to assemble). Without external power and with battery connected, green led 1 is on. With external power, orange led 9 in addition to that. FTDI chip is recognized regardless of power status, I can connect to the console. After pressing power button, green LEDs 2 and 3 and blue LEDs 4 and 5 light up immediately, and after that nothing else happens. Nothing on the serial console, no LEDs change status. Tried disconnecting the battery. Then without external power, all LEDs are dark (but FTDI chip is still visible), with external power orange LED 9 blinks, the rest is exactly the same: four more LEDs light up on pressing the power button, and no other signs of life. Looks to me as if either u-boot is absent / corrupted / inaccessinle, or the SoC does not enter boot mode. No jumpers connected. There is no CR1225 (the board arrived without it. But with the 18660 pack). Any advise? (I would be comfortable to play with low level boot tools).
