STM32H743 External loader problem

[YGU.1]

Hello,

I'm learning STM32 and wrote an quadspi external loader for my NUCLEO -144 (STM32743ZI) and 1M external flash. I've it tested in the Cube IDE and everything looks OK, I can read and write the external flash. When I use the loader in STM32CudeProgrammer I managed to read , but not erase and write accordingly.  Any help will be appreciated. Please find attachments.

Thanks

Have you mapped to your actual pins? Each Loader works for the chip but also for the pin distribution.
