Hi,I am facing untraceable issue with SBSFU. I integrated SBSFU features to our application running on device with 512kb flash. After downloading the firmware, during the swapping, it is throwing some abnormal errors while writing to addresses 0x0803...
Hello everyone,I have pretty uncommon question. I'm working on STM32WB with SBSFU, and I'm wondering, if it's possible to use non-secure boot with it? As far as I'm concerned, secure boot is enabled by default, but many security features can be disab...
