Do we have any mechanism to know about Software validation check status ??in case of reset, SBSFU will check for validity of application, before jumps to it. And in case of fail, it won't launch application, The failure status, how can we know ??Do w...
Hello Gentelman,In my algorithm, I need to calculate 2 types of CRC with different polynomials. Is there any way to avoid keep deInit and Init CRC, and change the value of polynomial dynamically?
Hey guys,I need to replace Uart for USB on my SBSFU local loader. I manage to create the USB comm in SBSFU quite easily, using UART structure provided in the SBSFU examples. My problem is when i receive firmware header, my code get stuck on the follo...
Greetings. I am developing a LoRaWAN application running on the STM32WL5, the application does work and makes use of the flash memory to store the application eui/network key (so that it is not necessary to recompile the firmware each time), the keys...

I'm trying to piece together the post-build process for flash integrity check using CRC. I'm running on an STM32F777.So far I've been following:https://community.st.com/s/question/0D50X0000B9vdDC/how-can-i-calculate-crc-of-image-in-post-buildand htt...
I would like to store two keys in the KMS as dynamic objects to use them in my UserApp project: One public ECDSA key One private ECDSA key For the public key, I have as example the SBSFU_ECDSA_1_Verify key so this should be fine. However, I don't kno...
Hello, I am currently working on a project on a STM32G483 microcontroller. My project contains the xCubeCryptolib library. But also I use the CRC device for the integrity of my variables that I save in the internal flash. During the development, I sa...
We want to store up to 4 Public Keys as backup, in case of any exploit in one KEY, we can switch to another.So, Can you provide any solution to store more than one Public KEY in SBSFU solution??
