Hmm, why would you need to skip SFDP parsing in 1 bit mode? What
actually fails when SFDP is parsed? Read/write/erase? BTW, did s25fs512s
flash ever with you controller before (i.e is this a regression)?

If 1 bit mode works fine, then probably flash FS in 1 bit mode and they
try read only mount in quad mode. Thus try and narrow down if the issue
is in read path vs write path.
