It likely isn't SPI, unless you tried writing a bootloader to it. SPI is empty OOTB.
Luckily, your PBP probably isn't bricked, but there may be a problem with eMMC or install on it. Have you checked to make sure the eMMC is fully seated on the board? Sometimes, they can get jostled and unseated, causing sporadic issues in booting. You can also try to boot from an SD if you use the internal switch to disable the eMMC. If you can do that, you're certainly not bricked. Once booted through SD you can use the switch to enable the eMMC again, and use a few commands (in the wiki) to rebind the eMMC for writing.
If after restoring or reinstalling to the eMMC, if you'd like to use BSP uboot to get s3 sleep, I'd suggest using pcm720's u-boot with ArgleBargle's script, as outlined in the previously linked wiki section.
Well, it was definitely SPI. if=/dev/zero of=/dev/mtd0 saved my bacon. Also discovered the recovery button for sure doesnt work and i did have to bridge the 2 pins myself. Even more dumbly, I was bridging the 2 wrong pins.
To top off the whole fun event. The metal cover, as I was putting it back on, gave me a paper cut.
I am in need of a vacation, problem is that i cant go anywhere because the damned virus.
Of note: it was PCM's nvm uboot that I did. The final line for spiflash was probably what got me.
