Hello,I am developing an application on STM32H7 MCU which uses SBSFU bootloader for secure firmware updates. I am trying to combine the SFB update package with some additional data in a single binary file that is sent for the firmware. To make this w...

It seems to be a recurring challenge in the community posts of getting firmware MPU configuration to work with SBSFU. We also had the problem of application firmware hanging when running it with SBSFU. A solution of clearing floating point unit flags...

Found from sfu_fwimg_regions.h:#define SFU_IMG_IMAGE_OFFSET ((uint32_t)1024U)So it seems to be hard coded value indeed.

Hi @Jocelyn RICARD, thanks I think I now have a more clear picture of what is happening. I think I misread your explanation in the other thread due to a typo. I understand that SBSFU is accessing the FPU in non-priviliged mode and accessing FPU in th...

Figured this out that I can just do a type cast and it seems the queues are already in the registry as long as the registry size is configured to be big enough in CubeMX.

After some testing, this modification actually seems to break SBSFU. It will compile fine but seems to just crash after starting and endlessly restart.
