I know this is a very old thread but for the record.

You have to set the Non-Volatile Status Register on MT25Q manually with your ROM writer.

Address mode selection: Must be 4-Byte address mode

Reset/Hold disable : Must be Disabled

Dummy clock cycles : Must be 4

.rdp file needs to be bit swapped, if you was trying to flash it with a ROM writer.

If you were using .jic file and doing JTAG-Indirectly programming, it will configure Non-Volatile Status Register for you automatically.
