During an electronic test, one of our guys reported that a module won’t boot. I checked the UART output of the card and now am suspected of a corruption at QSPI NOR flash on the module, that has a middle bootloader in it. I know it is possible to flash rootfs, kernel or dtb but is it possible to flash that QSPI from outside? The module is P3668-0000, the one with the SD card reader. I’m also appending UART output of the card in order for you to verify my suspicion. Also, if anything is not clear or something else is needed, I’m more than happy to help.
Thanks for your effort in advance.
