Hi,I'm working on the project which used RTT print as the debug interface and now integrated with SBSFU to enable the firmware upgrade capability, but after that I noticed somehow the internal flash been erased after I launched the RTTViewer and conn...
Hi,I'm testing SBSFU on Nucleo-G474RE, I have no problem to run up the reference code of SBSFU, but somehow secure boot loader didn't jump to my user application after the upgrade via UART Y-Modem after use my application code instead of original use...
I actually have not tried it out yet, but looking at the code, I think the SBSFU in the X-Cube-GCP package is not the same as there are some things that are very different (like the slot names for example)Need some advice from the ST reps hereWould ...

Hi could I find out if anyone has successfully got X-CUBE-SBSFU running on the dual core components? There does not seem to be any examples from ST for these use cases.The dual core components I am aware of are H745/755, and H747/757. However all of...
Hi,the HW PEC generation of the I2C Interface has two limitations that i have not been able to work around until now. The PEC calculation is reset after a stop, but can not be initialized after start. If you want to program a SMBus Slave that is capa...
Hello, in one my project I need to have SBSFU. On first version on my board I had STM32F405 uC and was successfully ported example STM32F413H_Discovery_2_Images_SBSFU. For test the porting I changed startup file in the discovery example for 405 s...
Hi AllI need to fill the security policy about STM32 crypto library(STM32CubeExpansion_Crypto_V3.1.0), and had three function name to fill.1, Entropy Health test2, Repetition Count Test3, Adaptative Proportion TestAnyone knows these?Regards,
Hi there,I am trying to understand the state of the option byte values in flash after a forced mass erase (changing RDP from level 1 to 0) for a STM32L151 (Cat.2).From my own investigation it appears that after a forced mass erase all the option byte...
I'm sure I'm missing out something obvious as I'm fairly green with limited programming experience, but I could not port the STM32F413 project to run on my own STM32F417 board. I've scoured this topic and followed Security Part6 - STM32 security ecos...
