Hi

when programming a Winbond W25Q64 as an EPCQA replacement I do get the same error message even though "Disable EPCS/EPCQ ID check" is enabled.

Any clues?

When I load a sof and then write the rpd file manually to a new W25Q64 I can verify that the content is correct but booting the FPGA fails. I do remember that with the EPCQ devices the programmer writes 12 dummy read cycles to the NV area of an EPCQ for an sucessful boot.

Is something similar required for an EPCQA?
