Just wanted to do a report to say that I was able to successfully write a SST25VF080B chip using the Rayer SPI external programmer support. Output:
root@sysresccd /mnt/temp/dfi % ./flashrom -p rayer_spi -w ./I35RD924.BIN flashrom v0.9.3-r1205 on Linux 2.6.35-std164-i386 (i686), built with libpci 3.1.4, GCC 4.4.5, little endian flashrom is free software, get the source code at http://www.flashrom.org
Calibrating delay loop... OK. Found chip "SST SST25VF080B" (1024 KB, SPI) at physical address 0xfff00000. Flash image seems to be a legacy BIOS. Disabling checks. Writing flash chip... Erasing flash before programming... Erasing flash chip... SUCCESS. done. COMPLETE. Verifying flash... VERIFIED.
This was required after a failed flash using winflash on a DFI BloodIron P35-T2RL board. Attempts to write the chip while still on the board (via the vendor provided header) failed as the chip could not be recognized so I had to remove the chip from the board. On top of that the 3.3V supply from the programming PC (from the ATX connector) did not appear to be clean enough even with a 1000uF capacitor right at the chip. I needed to power the chip with 2 AA batteries.
Thanks for the great software guys!
