Ah, crap. I just gave this another thought and now I'm convinced that it
can't work with the current code. dediprog_spi uses its own functions
for read/write that

SIO is generally enough.
I spoke too soon. It just flat out does not work to have sf100 and 256Mbit
part AFAICT

Got the fix. I used dpcmd to update the firmware on the FS100 to 5.5.3
Then flashrom can program it with ease.
And, ironically, while dpcmd can update the firmware, it still can't flash
the part :-)

I don't have a recommendation just yet, but a question:
Speed aside, is single bit IO good enough for 32MiB, or is DIO/QIO required?

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
yeah, also is there a programmer you recommend for 32MiB parts?
thanks

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

Erasing and writing flash chip... Erase/write done.
Verifying flash... FAILED at 0x0100! Expected=0x00, Found=0xff, failed
byte count from 0x-0x01ff: 0xffc000
Your flash chip is in an unknown state.
Please report this on IRC at chat.freenode.net (channel #flashrom) or
mail
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.
Looking for another erase function.

Hi Ron,

what does work? does flashrom detect the chip reliably?
What programmer do you use? what is your physical setup?
If these patches don't work, I would expect that the failure is not
about the flash chip model.

Hello Ron,
I do not have such chip, but I am aware there are three patches
regarding the S25FL256S: [1]
Best regards,

we're trying to use a 32 MiB part with flashrom and failing, I just wanted
to see if anyone else has had good luck here.
It reads back as all FF, but there is no indication of trouble.
