You've also contacted me privately. If the ones I've built aren't functioning, I'll need to work on them some more. Not sure how much time / resources I can commit to that immediately.

What you can do, is write your own BSP and prove that the QSPI implementation that you have is viable. That you can read, write, and erase from application space, in a manner that you can debug and instrument to validate design level functionality.

Hello @INaee.1 

I was wondering why I couldn't see your attached screenshots, I guess.

Overall, the flash loader for the MT25QL256A would need to be designed to handle the specific characteristics and requirements, including its size, timing parameters...
