Hi, just found FlashRom and looks to be a good base to start from for my needs.
I have a USB->SPI bridge device (MCP2210) and on it’s SPI bus is a “ S25FL128S” device.
It looks as though there is no direct support for accessing via the MCP2210.
I assume that I would need to write a “programmer” to get this to work ???
Yes, you will need to make flashrom speak to the MCP2210.
I have a MCP2210 access library that seems to work well via “/dev/hidraw” .
That should work so long as you can wrap generic data into a protocol that MCP2210 will understand.
I'm not sure about the existing library using /dev/hidraw... If you want to use libusb then you might want to check out ft2232_spi.c as an example.
Any advice/recommendations very welcome.
It may be that someone has already done this …
Regards, Bob
