STM32N6570-DK - Unable to debug

[chanchal94]

I have project consisting of FSBL+Application (writing AI code in application), I want to debug application code, but unable to do it . 
My core doubt is should I go via FSBL debugging or Application debugging while working with real time detection in AI ? I am very much confused in this application debugging, kindly address it.

I have ensured the external memory loader in cube Programmer as well as in debugger settings is same & loaded .
I had flashed the binaries in cube programmer FSBL-trusted bin at 0x70000000 and application trusted-bin at 0x70100000 and signed them also. 

I have attached a word document having screenshots of debugger settings and problems coming in debugging for each directly application and via FSBL. & one screenshot of external memory settings in .ioc file.

Thanks & Regards

While going via FSBL debugging , I am following these steps 

Checked for External Loader in cube programmer, Mass erase memory in cube programmer, Flashing trusted binaries of fsbl at 0x70000000 and appli at 0x70100000, closing cube programmer , open IDE and debug fsbl project.

 

Sometimes it is showing STM32 programmer failed and sometimes it is jumping to BOOT_Application, enters main code and crashes showing target not responding and it doesnt stop from stop button also.
