Hi,

Just got my Helios64 crashed: red error led is blinking.
I had a raspberry pi left logging on the USB-C and caught the crash:

Don't mind the ethernet port up/down messages (the connected router likes to reboot himself).
The system is running from SD card.

If you need any other information, feel free to ask.

Thanks.

Armbian is a community driven open source project. Do you like to contribute your code?

Im getting exact same kernel oops with

Linux helios64 5.10.43-rockchip64 #21.05.4 SMP PREEMPT Wed Jun 16 08:02:12 UTC 2021 aarch64 GNU/Linux

 

does your unit successfully reboot? mine fails to find the SD card at automated soft reboot

Sorry for the late reply -- haven't noticed that armbian forums doesn't automatically "follow" my own created topics.

I can't remember actually. I think that reinserted the SD card (or did something similar) and booted it successfully.
However, using the same SD card after the crash I've noticed some corruption:

$ free
              total        used        free      shared  buff/cache   available
Mem:        3956092 2316574242701033872     1578736         484 -2316574242698656516     3619336
Swap:       1978044       46852     1931192


That was hella a lot of RAM and surprised that it was still running.


At the end, I've decided to start all over again and moved from SD card to internal eMMC.
