Thanks for your tip.

I've attempted this method, but it hasn't worked for me.
Could you provide the SPI details for this board so I can map it in driver code
and from userspace and then attempt to erase or reflash the image?

on my board
[    1.282609] mmcblk0boot0: mmc0:0001 SLD64G 4.00 MiB
[    1.285862] spi-nor spi1.0: unrecognized JEDEC id bytes: ff ff ff ff ff ff
[    1.285967] mmcblk0boot1: mmc0:0001 SLD64G 4.00 MiB

This board does not return to the U-Boot prompt.
So I cannot debug this further.
