Ok this happened again and I'm out of ideas. @Werner Could you tell me the dependencies for the boot process on this board and how I could read out the values like the boot loader to verify they are still the same? There should be nothing wrong with cutting power right? I have had raspberry pi's be cut from power daily for years without issues and I assume it would work the same for the odroid boards?!

Finally got around to debug this: Previously I had the system on an nvme drive and the bootloader on spi After reinstalling the system and bootloader both on mmc flash, I eventually ran into the very same issue. According to the logs, the boot bails with the following error: Log1: When I remove the nvme drive, the boot process works just fine for some reason: (boot log after nvme removal) Log2: When I reinstall the nvme, the boot fails again. However, booting from sd-card (using recovery button) and reflashing the bootloader to the mmc fixes the issue as well with the same result as removing the nvme drive had, resulting in the same log2 as above. I had fixed the issue before by reflashing the bootloader to spi but just like yesterday, it eventually stopped booting again until I reflashed the boot loader. There isn't anything particular happening before this occurs, though the last few times it was always after the system had run for some time. After cutting power (without shutdown) and booting it again, the issue would appear. (The device is always cut from power instead of shutting it down, but there was never an error on any drive due to that). The issue also did not show when the device was just turned of (without power) for a day or two. It seems to trigger quite randomly. I already tried to erase the spi flash to avoid any old entries messing up the boot order but without effect. Any clue what I could try next?

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

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.
