Merging SBSFU(.hex) and Application(.sfb) into single hex file not working

[Tarun]

Hi Community,

I'm in a process to combine the SBSFU and Application file into single intel hex using srec_cat.exe doesn't work.

srec_cat Application.sfb -binary -offset 0x08010000 -o APP_Offset.hex -intel

srec_cat STM32G0B0RE_SBSFU.hex -intel Application.hex -intel -o Combined_App.hex -intel

Combined_App.hex always executing in bootloader and not jumping to application after several power cycles.

Is it because of encryption/signing?

Can anyone suggest better approach to deal with this?

Hello @Tarun ,

Can you give more information on the error message you get on the terminal and could you give more details about the process you followed to install the combined app . Lucking a lot of context to further guide you throw your manipulation .
