Hello , i own a gq4x4 , software to the latest 7.11 but its slow. Im mainly programming W25Q64FWSIG or W25Q64CV (8 meg flash) and its taking its time ( ~ 8 minutes per operation ) doesnt matter if i read or write.
Back in the days i had a gq-4x which was working like a charm.
This is the output from gq4x4 for a w25q64fwsig (1.8 , im using adapter) - doesnt matter as im getting the same results on the 3.3v ones eg w25q64fvsig ID check OK Reading... Buffer Elapsed time: 282.26 seconds. Read completed.
