HA had been working for more than a year without an issue and it suddenly crashed, it was unable to start. I backed up my files, formatted my SD card and got it ready for a fresh install using the latest instructions (Raspberry Pi - Home Assistant). However, when I plug it in, it gets stuck on a Uboot loop without any obvious (to me) errors. Is my SD card dead? Is it an issue with my power supply? With my RPi? I’ve seen similar topics but none with that same issue, also the solution to most of them was to reinstall which is not working for me. Any insight would be greatly apprciated!
If you updated to Home Assistant OS 15.0, see here: Home Assistant OS 15.0 - no need to skip.
Is it RPi 3 32bit? In that case it would be this: Raspberry Pi 3 32-bit fails to boot Home Assistant OS 15.0 · Issue #3965 · home-assistant/operating-system · GitHub
Could you post what SD card it is? It seems that some are problematic since the initial_turbo change that we later reverted, but I haven’t been able to reproduce it even on 8 different SD cards I have available. 15.1.rc1 has that change included, but if I were you, I’d also reconsider if you really need to run 32-bit version.
Whatever hardware you are using, it is trying to boot using the network. Could be that the SD card or the bootloader can’t be found.
It is a RPi 3, but it’s the B+ so I think 64 bits. The SD card is a Lexar 667 128GB.
The initial_turbo = 0 appears to be working for me.
