I understand your point but I don't have enough part number and I can only to test on this one. I will verify this patch too and put my review and drop my personal one. Anyway can you ask if the first 0x8000 are considered by boot rom? I'm trying to boot from qspi an imx7d board and I create the parameter using the files/qspi-nor-spansion-s25fl128s-config but not sure if I need to flash from 0x400 or from 0x8400. And then I think that bootloader should go from 0x1000 or from 0x9000 correct? Then from BOOT_FROM I choose qspi but what is the DEFAULT_ADDRESS 0x1000 or 0x400?
Don't understand either does this "Disable 4-KB erase command for SPANSION S25FS-S family" (spansion_s25fss_disable_4KB_erase) is an issue workaround or something like hybrid configuration feature for spansion parts?
Please refer here.
Thanks for the pdf, So the lower 8 4k sectors are unaffected even if we do sector erase(d8h)? What if we do 4k erase(20h) whole flash all effected?
thanks!
