Hi all,

I'm trying to dump a chip using the following command:
sudo flashrom -p ft2232_spi:type=232H,port=A,divisor=16 -r dump.rom -V

For some reason I'm getting an error. Can anybody help me?
"Initializing ft2232_spi programmer
Error: Invalid device type specified.
Unhandled programmer parameters: port=A,divisor=16

I also tried: sudo flashrom -p ft2232_spi:type=232H -r dump.rom -V
got the same error.

help :)

Thanks!
