ODROID-M1 issues with spi boot after power loss

[ceri]

When the ODROID-M1 is setup to boot from SPI with the system installed on a M2 ssd, power loss seems to lead to an unbootable system.

Once an SD card with armbian is inserted and the system is booted through the recovery button once, logged in* and then shutdown normally, the system boots again from SPI.

* Without login and regular shutdown of the system booted from sd card, the issue remains

 

I have observed and reproduced this issue several times in the last year.

In my case the M1 is connected to a power strip that turns on and off the multiple devices.

When I forget to unplug the M1 and it gets turned on and off several times over a day or more, the issue appears.

When I turn it of manually I could not yet observe the issue, so it may be related to being booted and turned off multiple times in short order.

 

When I investigate the journal of the last boot circles, there is nothing there, as if the boot process never started, leaving me to suspect an issue with the bootloader in combination with SPI and power loss.

unbootable

This error description leads nowhere. Hook up a debug serial console to get an idea what happens inside while the system does not boot. Share the logs here. Also verify powering and wiring.

I was hoping that the description would make it easy to reproduce to find the issue.

If that's not the case I can try to find the required cable somewhere nearby to give it a try myself.

 

Update: Any recommendations where to get a UART adapter in germany when amazon is to be avoided?
Even conrad does not have any listed that I can find
