Yet another Pinebook Pro won't boot thread

[akash3995]

My old Pinebook Pro wouldn't boot (it tried, but reported boot error messages and hung). It has no eMMC in the laptop at all (removed long ago), but I used to boot Manjaro from the SD card.

I flashed Manjaro ARM Generic to the SD. No boot at all (no power lights, no response).

I flashed Tow-boot to the Pinebook's SPI from the SD card. This booted, and the flash was successful.

I flashed Manjaro ARM Generic back to the SD card, but it does not boot. No power light.

I flashed the old Manjaro image for the PBP to the SD card, but that does not boot.

I re-flashed Towboot to the SD card. That boots!

Edit: I ended up using Towboot to erase the SPI, and then reflashed Towboot to the SPI. That gave me the Towboot boot menu. I think we're onto something here!
