STM32H563ZIT6 external loader fail

[MicheleMalaspina]

I'm currently developing an external loader on STM32H563ZIT6 development board.

I'm facing an issue on programming with cube programmer in the image below

The problem I think might be linked to interrupt handler of systick.

 I've attached the Loader_src.c file where I had developed the functions used by Cube Programmer; also attached the linker used.

The low level functions linked to XSPI communication are properly working, because I had tested in debug erasing and writing sectors.

I need help to figure out the problem.

Thank you so much @Saket_Om for the guide, I've already copied the git hub repository linked, but the problem is stll present. I had put some debug pins in Init function and it seems that Init is not called. Could you please give me some advices on where to check? Linker error?

Hi all,

I have the same problem using NUCLEO-H563ZI .

In debug mode, all functions control external memory without any problems.

In release mode, doesn't work nothing.

I inserted some LEDs to follow  the startup process but it seems doesn't running.

(obviously STM32Cubeprogrammer give me errors because is not able to connect to External loader)

I share also my simple external Loader project source,

I hope someone can help me!

best regards.
