Getting "Cannot access memory at address" error when trying to follow NUCLEO-N657X0-Q tutorial

[willisk]

I tried to follow this tutorial: How to build an AI application from scratch on the... - STMicroelectronics Community , could not figure out how to enable NPU RIF, so i skipped it. I tried to debug using the FSBL main.c, the blue led did turn on, but i got the error in the screenshot when trying to launch application in FSBL main.c. Project: willisk0612/nucleo-getting-started

I had the same issue, but I managed to solve it.

For RIF - NPU, you can configure it in the RIF Panel before setting up X-CUBE-AI.

In XSPI2, set the following:

Chip Select Override: NCS1 -- Port2 --

Memory Type: Macronix

In EXTMEM_MANAGER → Memory1 →

Number of memory data lines: 8 LINES

After applying these settings, it worked for me.
I recommend creating a new project and setting it up again.

My English may not be perfect, but I hope this helps.

Thanks for the answer. It turned out i had to disable X-CUBE-AI software pack, enable NPU in RIF panel and enable X-CUBE-AI. I tried implementing the XSPI2 and EXTMEM_MANAGER changes you mentioned. I still get the same error when trying to debug. I also tried signing, flashing FSBL, Appli and weights, i did not get any LED response or COM response. I updated the github project repo above, so you can see my files. If someone has a working x cube ai stm32n6 nucleo project, i would appriciate a github or zip file, its very frustrating to fight these errors.
