I have been using my gq-4x for several years now.
I updated the chip definitions to include the w25q256 but I am lately having a problem.
The chip verify fails after programming at the same address 0x700000.
the gq-4x programs other chips flawlessly, although not this size.
I have tried both a different brand new chip and also adding auxiliary power, same result.
Has anyone else been successful in programming a chip this size?
