please don't attach proprietary software images, you are probably not allowed to. (And we actually have a 256KiB limit on the mailing list, I guess your message was forwarded by accident.) > > Board: Gigabye GA-N3050-D3P Chip: MX25U6435F (8192 kB) Flashrom ver: That chip is a 1.8V part, I hope you are using a voltage shifter? > 1.0.1 Using Raspberry Pi and Pomona 5252 for SPI interface Directly attaching a programmer via a Pomona clip is often done, though generally not a good idea unless you know the board design. It's hard to tell what is really going on on the board, what other chips are involved, etc. You can even harm the board if you attach voltage via the programmer. > Verifying flash...

It could be something on the mainboard interfering, but it could also just be a flaky connection. First step is always to test the reliability of the connection, e.g. dump the whole chip once and then verify the result multiple times. A little brute force might also help, generally discouraged but as you have started anyway: You can try again and again and see if the "failed byte count" decreases. If it does, you can try again until everything is fine. Hope that helps, Nico _______________________________________________ flashrom mailing list -- [email protected] To unsubscribe send an email to [email protected]
