I’ve double checked that the chip is supported (it’s the MSI motherboard MS-7760), I’ve double and triple checked the wiring to the JSPI1 header (9-pin variant) and I’ve tried pulling the hold pin high, low and even leaving it disconnected… Which mainboard or programmer you tested in the subject line.Įrror: Image size (8388608 B) doesn’t match the flash chip’s size (0 B)!” Please include the flashrom logįile for all operations you tested (see the man page for details), and mention Work correctly for you with this flash chip.
