Getting 4-byte address support in is something I'm
interested in as well. In fact I have parts coming in the mail this week :-)

I just started experimenting with flashrom using a Dediprog SF600 this
weekend. I noticed that there’s no support for any of the 256Mb or 512Mb SPI NOR parts (4
byte addressing an issue?).
The Dediprog SF600 has commands for 4-byte addressing, but I was not able to get them
working in the time I had to play with it. We can probably also ask Dediprog if they have
an updated command spec, maybe there was a problem in the one I was looking at.
Is there a newer version than 0.9.9 that I should try? I did find that the Google fork
for chromeOS has a number of these parts (W25Q256, N25Q256, SST_25F256).
Yes, but the systems those went in treated them as 16MB parts. The firmware (coreboot) is
small so there wasn't really need for the extra space.

can also test with an FTDI232 based programmer. The boards I can test with currently have
various versions of 25q512, 25q256, 25q128 and 25q32. Functionality with the smaller parts
I'm a bit late to the party here, but in case it's relevant: I
successfully programmed a Micron N25Q512, which is a 64 MByte SPI
flash with 4-byte addressing, using patches originally from Boris
Baykov on top of a more current flashrom. See
Both FT232H module and STM32 Blue Pill board with stm32-vserprog
firmware work as programmers.
