Hi all,
SBSFU ported to many custom boards and in projects, and is working as expected.
But in a project with Touchgfx throwing error "error was: Firmware signature check failure." on Installing update FW from download area.
As it is working for other projects without Touchgfx,
I'm really clueless where to look?
I'll appreciate for any info.
With regards

Hi @JChou.1 ,
what particular MCU are you using? What development tools?
Sometimes when there is code in ITCM or CCM memory range, the prepareimage.py is confused about it and creates incorrect FW image. Or it could be something else, please provide details.

Hi Jhoud,
MCU : STM32F446
Development tool: STM32CubeIDE 1.5.0
SBSFU type: 2_image
As the complete image (.bin generated by prepareimage.py ) runs and only the .sfb on fw update causing error.
