I am trying to implement a firmware integrity check using the Cryptographic Library (X-CUBE-CRYPTOLIB) for this I have to calculate the SHA256 checksum and then determine the padding and include it in the binary that I will upload to the board.I've b...
Hello all.I'm trying understand SBSFU source code. At this time, I meet very confuse code.Middlewares/ST/STM32_Secure_Engine/Core/se_interface_bootloader.cIn the SE_Startup() function, there is function pointer casting code as below:SE_StartupPtr = (...
STM32 has the capability to perform checksum self checking.If no, there is some way to verify that the program have been loaded properly.
Hi all,I generated the SBSFU file. now i am getting another issue, I was thinking to program the .bin file using CubePrg (DFU method)so I loaded the .bin file which created using sbsfu, then I set the start address as 0x080000000 or 0x0 and trying to...
I have just updated a board design, replacing the STM32L433CC with an STM32L4P5RE. I have no problems using the RNG on the L433. However, with the L4P5, I get only one result from the RNG before it give a seed error.RNG: CR = 00800004, DR = 9a4c8249,...
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...
