Failed to erase memory with stm32cube AI studio on stm32n6-dk board

[SBaro.11]

Hi all,
I’m trying to follow this guide here but when I try to run the model on target I always got an error 

failed to erase memory.Here is the log. I’ve also set external loader from cubeprogrammer to MX66, and if I try to erase memory from cube programmer I also have an error, loose comunication with the board

It looks like the issue may be related to the external flash or loader configuration, especially since CubeProgrammer also loses communication during the erase. Have you tried lowering the SWD frequency and testing the MX66 external loader separately?

[SBaro.11]

Yes I’ve set the external loader as you can see here :

I did a test with 3300KHz frequency setting I have the same issue with cubeprogrammer trying to Full chip erase here is Log output (0x7000000)

 

[Mancy34]

It looks like the board is detected correctly, but the issue is with the external flash communication. Since the MX66 loader is already configured, I’d double-check the external loader version and try lowering the SWD frequency. The fact that CubeProgrammer also fails to erase the memory points more toward a loader/connection issue than AI Studio itself.
