So recently I flashed Orange Pi OS to SD card, booted from there, updated system, firmware and flashed bootloader to SPI flash. I already had an external HDD with Armbian flashed, and tried to boot from there, but no luck. Afterwards, I tried to boot Armbian from SD card, but I can't boot any system that is not Orange Pi OS (and especifically, it needs to be from SD card, can't also boot from USB even in OPi OS). Tried with different SD cards and USB devices, no luck
I believe I need to erase SPI flash in order to boot from SD again, but, how can I do it?
Used latest OrangePi OS and Armbian Jammy CLI from 23/01 (stable release)
I will use the NPU found in the Banana Pi, since I'm currently developing for it on the Orange Pi 5 4GB RAM. My limitation is there, in the low 4GB of RAM that I want to use for LLMs. If someone is interested: https://github.com/Pelochus/ezrknpu
