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 > Set the jumper as shown in the picture to boot from SD-card. > Once booted remove the jumper to erase or update the SPI flash from U-Boot. > This board does not return to the U-Boot prompt.
