Hello,
using NOR flash (MX25LM51245G Datasheet) initalized on a STM32L4 as QSPIF, I’ve got the following error during initialization:

Does anyone have an idea how I can properly initialize the flash?
Thanks,

Edit: Checked the data sheet more closely and new macronix devices changed their status register size and entries. Will give a follow up as soon as I’ve finished fixing the QSPIF lib
