Re: [flashrom] MX25L25635E / 4 byte addressing - flashrom

5 Oct 2015

      Hello,
I have used the same patch set on trunk to flash W25Q256 (WSON version).
I still need to build a system to check what was actually written.
(I'll try to flash Openwrt to the chip and run in on a MT7620 with
modded U-boot).
If there is anything I can do to move this along, please let me know.
Kind regards,
Michaël Zweers

Nope, there isn't, at least nothing that I know about or that will hit
vanilla flashrom soon.

Thanks for the quick reply.  I did some digging, and found a patch set
from January, resurrected and forward ported to the current tip of
flashrom on github.com/petermartini/flashrom
http://github.com/petermartini/flashrom, and confirmed it worked well
enough that it worked on my chipset.
This was Boris' work, and I guess it was incomplete / petered out before
being committed; does it ring any bells?
It seems the thread petered out around
http://www.flashrom.org/pipermail/flashrom/2015-January/013168.html.
I'm happy to help, if I can, get that patch set merged in if there's
work to be done on it so I can upstream my chipset's specs.
Thanks!
Peter
