It assumes that an ID of 00 00 is a "generic SPI chip". Instead it means there is no chip connected. ./flashrom -pdediprog flashrom v0.9.1-r878 Calibrating delay loop... OK. Found chip "Generic unknown SPI chip (RDID)" (0 KB, SPI) at physical address 0x0. === This flash part has status NOT WORKING for operations: PROBE READ ERASE WRITE Please email a report to [email protected] if any of the above operations work correctly for you with this flash part. Please include the flashrom output with the additional -V option for all operations you tested (-V, -rV, -wV, -EV), and mention which mainboard or programmer you tested.
