STM32H745XI Dual Core External Bootloader

Hello,

I have developed a external Loader for my custom projekt. It uses a W25Q128 QSPI conected to bank 2 and alternative Pin of CLK. (Worse!, but it is so...) So i Have no exactly example for it. Also it is a Dual Core, and no example i find have special definitions for it.

I worked more days on it and it worked perfekt (now!) in a Cube Projekt.

Erase, write and read (manual) and memory mapped mode are perfect.

If I compile the stldr file, I can load ist in Cube programmer and stm prog utility.

But then I could cry. I can't do anything. No read on QSPI and so on.

....

I think i will have trouble with the m4 Core. The M7 Core must wait for him.

I don't know. How you can help me. What is wrong. Have you any Idea?
