please see our FAQ[1]. You are running the SPI bus at an unknown (likely much too high) clock. > > I put exactly what is listed as type and says unknown… > > pi@pi0w:~ $ sudo flashrom -L | grep MX25L6406E/ > Macronix MX25L6406E/ PREW 8192 SPI Looks like somebody put a line break into the identifiers... you'd have to write "MX25L6406E/MX25L6408E"; it's one entry for both chips. But that would only help if flashrom could detect the chip.
