I know that STM32H753 is pin-compatible to STM32H743, and as far as I know also code-compatible for most intents and purposes. The only difference seems to be the Crypto hardware acceleration. So I assume that I can run code from H743 on the H753 wit...
I am using the KMS of SBSFU to store my TLS certificates during the provisioning process. When I flash a new user firmware application the certificates inside the KMS are deleted too. So each time I want to run new user firmware, I have to go through...
Hi,In TFM and SBSFU applications, by default the anti-tamper protection is enabled for both internal tamper events and external tamper events. It is activated at the start of TFM_SBSFU_Boot, and remains active.In case of tamper detection, sensitive d...
Working on a project using STM32G071CBT6. Using STM32CubeExpansion_Crypto_V4.0.1 Projects NUCLEO-G071RB Applications RSA PKCS1v1.5_SignVerify RoutinesTrying to sign a 138 byte msg.cmox_rsa_pkcs1v15_verify() returns CMOX_RSA_AUTH_FAILAny suggestions?
Hi,I'm trying to implement secure boot and secure firmware update on STM32F415RGT6 but I'm having hard time with SBSFU code.I already compiled the example STM32F413H-Discovery making adjustment for flash and ram in linker file. Then I runned the SBSF...
Also, apparently CVE-2020-27212 means that you can bypass flash readout protection. Is that a correct reading of that CVE? Note that searching both the ST main site and the community site produce no hits for either CVE, and trying to determine the ...
Hi, I try to download X-CUBE-CRYPTOLIB but after clicking on ACCEPT "terms and conditions" I always get 404 Error
I set level to DC(level1) and now I am not able to connect the board to Cube Programmer and throws "Connection to target must be established before performing the read command." https://youtu.be/LG474meMnagI was using this above video for reference. ...
We have plan to support application down-loader from Application context. It means Application has ability to receive new application over the air. Not SBSFU.In case of Active application got corrupted somehow, then SBSFU is locked the MCU, as we los...
