Eliminating Swap Region to reduce boot time (STM32H753ZI)

Hi Team,

I am new to SBSFU, and our team requires two image examples. To reduce boot time, I need to eliminate the complete swap region, and I am currently working on this.

  1. I will flash the SBSFU binary, including only the SBSFU application, using the user button to update the firmware from a local download.
  2. After the download, I will decrypt the data and attempt to start the application from the download slot.

Could you please suggest the best approach to eliminate the swap region?

Regards,
Rahul

Hello @rahulz916 

If my understanding is correct, you ask for SBSFU with single image where no swap area is allocated. 

If it is the case, refer to UM2262 "Appendix C Single-slot configuration" and to the project provided in the SBSFU package with single image for STM32H753 (~\SBSFU_Legacy\STM32CubeExpansion_SBSFU_V2.6.2\Projects\NUCLEO-H753ZI\Applications\1_Image)

 

Best Regards
