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??
Hi,For production purpose we designed a control board for the test jig which does unitary and RF testing as well as the programming of onboard SoC and MCU, the STM32 target in this case is an STM32F411CEU6, the test jig control board is also based on...
please share with example
I am using the SBSFU project for OTA.I have linked my UserApp successfully with SBSFU projects and firmware up-gradation is working fine when FIREWALL protection is disabled.I am using the STM32L4 series controller and am aware of L4 series firewall-...
I would like to place some of the functions of ST Crypto library (cmox_crypto) into the ITCM to increase the performance on STM32H750x MCU. I would also like to place some of the associated data (tables) into ITCM or DTCM. However, the functions are ...
