Ok, it compiles ;) In case anything works with this [1], it adds about 6 different paths depending on protocol versions and what the chip sup- ports; would be nice to have most of them tested. For instance testing the S25FL256S patches one by one as they add different ways how to handle the higher addresses. Also, in case you can downgrade Dediprog firmwares, a test with something <5.5.0 would be good as well.

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 likely don't call into the common, 4BA aware code.

I spoke too soon. It just flat out does not work to have sf100 and 256Mbit part AFAICT On Fri, Sep 28, 2018 at 11:19 AM ron minnich wrote: > Got the fix.

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 :-) ron ___ flashrom mailing list flashrom@flashrom.org https://mail.coreboot.org/mailman/listinfo/flashrom

If you want programming to be fast (almost on par with Dediprog): Either Raspberry Pi or Beaglebone Black. The Beaglebone Black has an abysmal internal power supply and for any in-circuit flashing you'll need an additional 3.3V supply for the flash chip. For standalone chips it usually is sufficient, though. The Raspberry Pi has SPI disabled by default, you need to add dtparam=spi=on to the file /boot/config.txt .
