I was able to test this and it works with one small change (see comments).

I used an SF600 with firmware 7.2.21, with W25Q256JVFM and MX25L25735FMI and wrote to 1MB ranges in the lower and upper halves of the chip.

• File dediprog.c:

  • Patch Set #1, Line 399: data_packet[3] = WRITE_MODE_4B_ADDR_256B_PAGE_PGM_0x12

    For some reason I cannot explain, this needs to be WRITE_MODE_4B_ADDR_256B_PAGE_PGM. That is the only way I have been able to successfully write using native 4BA commands.

    I am not sure what WRITE_MODE_4B_ADDR_256B_PAGE_PGM_0x12 is supposed to do...
