SBSFU - FW too big

AKhri.1

I am adapting the NUCLEO-H753ZI single-slot project to work on a NUCLEO-H745ZI-Q board.

My development environment is linux and I am using minicom for the ymodem upload.

When flashed, the binary seems to function perfectly, but when I corrupt the image and attempt to upload a new sfb file the board keeps failing the download saying that the firmware is too big.

The project I am working on is largely unmodified other than setting the flags for the minicom communication in app_sfu.h and the workaround for the double include for the userapp.

Below are screenshots of the problem:

Hello ,

I'm sorry I've just seen your request.

I guess you probably solved it now.

I made a quick check on my side with STM32H753 project of SBSFU V2.4.0, using the corrupt image menu and flashing again the image in the 2 images project and it works fine.

If you still have the issue I would need you provide your modified files to that I can reproduce and debug.

Best regards

Hello,

I am also adapting the NUCLEO-H753ZI single-slot project to work on a NUCLEO-H743ZI2 board and got the same error using minicom on linux.
How did you fix it?

Shifting the DWL area pointer by the received header size (192 bytes) fixed the issue for me.
