SBSFU Application upgrade fails

Tarun
Associate III

Hi,

I'm working on STM32G0B0RE custom device. I have ported SBSFU through USB CDC. I'm able to program SBSFU and application. The application is working as expected but when I try to upgrade application it fails to rewrite the application header in the flash. I have no issue when application programmed first time and no protections enabled yet.

The highlighted function SE_SFU_IMG_Write returns error when I try to write 320 bytes header.

Can someone help me on this?
