> The original W25Q32 doesn't have the CMP bit. I didn't found any datasheet without the CMP bit, but now that I know these chips had a new batch (with mandatory SFDP support) starting from 2016, whereas the datasheets I looked at were from 2017, it is possible that I couldn't find an old enough one. Which brings me to a more important question: can we anyway enable CMP anyway? I contributed several patches for that already (merged). I guess if the CMP bit is not present, the old software does not use it. If it tries to use it, normally the verification should fail. Thanks, Miquèl
