I am trying to use flashrom and a TinCanTools flyswatter2 to program the
Winbond W25Q32 flash via SPI. After researching how to use flashrom and the
flyswatter, I tried the following:
robert at STS-MAX:~/Downloads/MB_UEFI_Firmware_v1.00$ sudo flashrom
--programmer internal --write MINNOW.fd
[sudo] password for robert:
flashrom v0.9.6.1-r1563 on Linux 3.13.0-39-generic (x86_64)

Descriptor region (0x00000000-0x00000fff) is read-only.
FREG2: WARNING: Management Engine region (0x00003000-0x001fffff) is locked.
Please send a verbose log to flashrom at flashrom.org if this board is not
Writes have been disabled. You can enforce write support with the
ich_spi_force programmer option, but it will most likely harm your hardware!
If you force flashrom you will get no support if something breaks.
Found Winbond flash chip "W25Q32" (4096 kB, SPI) at physical address
Write/erase is not working yet on your programmer in its current
So apparently it does find the W25Q32 chip, and I may be getting close.
Before I proceed to possible destruction, does anyone have suggestions?
