Here is my development environment:
Software: STM32Cube_FW_WL_V1.3.0
Hardware: NUCLEO-WL55JC1
When I run 1_Image_BFU based on the original project, it works fine and can be upgraded in different versions. But when I ported my own project to use, the upgrade was abnormal and didn't start. So I want to enable SFU_DEBUG_MODE to see what exception is happening in 1_Image_BFU. So, I enabled SFU_DEBUG_MODE in app_sfu.h Then I compiled the project there is a reminder of memory overflow.
then i add SBSFU Code region and other regions in mapping_sbsfu.h,like this:
and mapping_fwimg.h
Then recompiled 1_Image_SECoreBin, 1_Image_BFU, and 1_Image_UserApp, it was successful without any errors.
I use tool to 'full chip erase' and programming BFU_UserApp.bin at 0x08000000.Then connect to the UART tool to view logs.
when i load the UserApp.sfb file and update it.
The fw seems invalid.
I use tools to read memory: The location of the application slot appears to have been erased
Take a look at the memory of BFU_UserApp.bin , it doesn't seem to be at this address but at 0x00010000
Anyway, I suspect the generated bin file address anomaly caused this.Maybe something else was missing,Is there a professional who can take a look at it, thanks!
