Pardon my ignorance, but why is u-boot on SPI a no-go for us right now? I've noticed that other rk3399 hardware has achieved it (Khadas Edge has a script to flash u-boot to SPI in their wiki.) Would it not be possible to adapt these existing tools to flash SPI on the PBP?
Awesome work on this modification, btw! I'm looking forward to loading it onto my CrOs install today.
Thanks!
SPI is a no-go for the same reasons Pine64 ships their U-Boot on eMMC: there is no safe way of flashing it and no easy way to recover.
Plus, I guess there's still work to do: it would be nice to have display and keyboard working in the pre-boot, before they're initialized by the kernel.
