External loader issue with STM32H743 and W25Q256

Hi,

I am using Clives loader for the STM32H with the correct pins etc but it never works in the STM IDE, so I thought I would follow controllertechs videos to try and make my own loader, that didn't work either, but I did verify all the QSPI parts reading/wriitng etc are working. I also learned a good test using the CubeMX Programmer (and that fails using my loader for a different reason) but, I then thought OK will test it with Clives and MX Prog, and that fails on verification when I try and load a 1MB test file. I have emailed Clive and he has been incredibly helpful already, but thought I would also ask in the community in case someone has a quick solution?

Hi Soflt I updated my original post. The key thing is to turn off the MPU.
