Hello , everyone.
I am currently working with the STM32N657X0H3Q device on the NUCLEO-N657X0-Q board.
Following the official Template_FSBL_LRUN example, I successfully generated and signed both FSBL and Appli binaries using STM32CubeIDE and STM32_SigningTool_CLI v2.19.0.
In DV Mode (BOOT1 = High), I programmed:
- The trusted FSBL binary to address 0x70000000
- The trusted Appli binary to address 0x70100000
After programming, I set the BOOT1 jumper back to low (BOOT1 = 0) to boot from external XSPI Flash.
However, after reset, the board appears unresponsive — no LED blinking or visible activity from the Appli.
As suggested in the documentation, I have enabled the NO_OTP_FUSE preprocessor macro in the FSBL project.
I would appreciate your help in identifying why the application does not execute after the FSBL handover.
You will find the signed binaries and project files attached for your reference.
Best regards,
Han
