yeah, also is there a programmer you recommend for 32MiB parts?
Any programmer that can handle arbitrary SPI commands, e.g. single- board computers with native SPI interface (RPi, BeagleBone Black etc.), CH341A is popular but slow, FTDI based programmers are faster (FT232H/ FT2232H/FT4232H), serprog programmers (some may not be too slow), Bus- Pirate rather slow too.

Ah, dediprog... you happen to have the one programmer that is hard to support.

hmm, is this useful?
Found Spansion flash chip "S25FL256S......0" (32768 kB, SPI) on dediprog. Erasing and writing flash chip... 4-byte address requested but master
can't
handle 4-byte addresses.
That is expected, native 4-byte instructions are tried first but they are not implemented yet for dediprog. It should fall back to another instruction though. Unless the dediprog resets the chip between in- structions, it should actually work. Though, David seemed to have trouble with that too, I didn't test it myself yet.
Looking for another erase function.
Can you please just post the whole log (best taken with -o logfile).
