AFAIK, the SPI has been flashed with some form of bootloader, and you aren't booting from eMMC, you won't be able to boot from a SD card, the boot order is eMMC -> SPI Flash -> SD -> USB. As far as erasing from GPIO, I'm not sure... I'm guessing it's possible if the SPI Flash is sharing the common SPI pins. Path of least resistance will be eMMC + a USB/eMMC adapter. I'll write a SD card image for rock64 and double check tomorrow though...
I have no issues booting from SD with uboot on SPI. Could that be because the uboot on SPI boots the system on the SD? Doing it this very moment testing OMV 4, so I know it works.
As for OPs pickle, I guess lifting one leg of the SPI chip would be a hardware solution - it can always be resoldered.
Thank you all for your help and suggestions! As for lifting legs of the SPI: that would definitely far beyond my capabilities!
Maybe shorting some of the pins during power-up could be a workaround?But - as far as I understand the situation, getting and using an eMMC card would be the easiest way of solving this, right?
