Like I said, I don't really know.  The way I get out of it is boot to the SD card and flash one of the SPI flash's that preceeded the main-line U-Boot SPI flash.  PM me and I can get the file to you.

Is this the BSP uboot you mentioned? https://github.com/pcm720/rockchip-u-boot/releases

There is a difference between the BSP uboots and mainline concerning waking NVMe drives, that hasn't quite been figured out yet. I believe there are some looking to find that difference and implement it within mainline, but it hasn't been found yet.

I just grabbed the SPI u-boot file from that location (https://github.com/pcm720/rockchip-u-boot/releases), dd'ed it to the device and rebooted. The NVME get recognized  and my system is properly booting again.

Thanks a lot!

i would either use mrfixit2001 v2.0 (patched bsp) or pcm's 2020.07-1 (patched mainline) uboot:
