Hello Tarek, Thank you for your prompt response. The option bytes BFB2 is enable, my program boot on bank 2. I have no direct error coming from openocd. When I start debug session, the program is flashed on bank 1 instead of bank 2. To make it work, I have to flash manually the program on bank 2. Julien
How to run debug session on bank 2 STM32G4?
