HelloI'm starting to implement AES-GCM on STM32H753 (rev V).I've found an inconsistency between the HAL and the Ref Manual.The STMicro HAL for AES for STM32H7x3 is setting some bits called NPBLB in CRYP_CR register if the product revision is above re...
I have requested a X-CUBE-CRYPTOLIB V4 download last week, and no answer from ST.I have indicated all requested information and received an acknowledge, but no link to download the library.Could you tell me why ?
I received today the link to download version 2.6.0 of X-CUBE-SBSFU. Is it possible to install it along with the other X-CUBE Packages within the STM32CubeIDE? I successfully verified the integrity of the downloaded file and tried to install it using...
I am using STM32CubeExpansion_SBSFU_V2.6.0 to test SBSFU on B-L4S5I-IOT01A board.I am using the projects in the Projects/B-L4S5I-IOT01A/2_Images_KMS folder with STM32CubeIDE. I did not change or modify anything regarding the files.I first built the S...
@Jocelyn RICARD My user app logs a status and error messages to an SD card. I would like to log all the SBSFU startup messages to the same SD card. Would I introduce security vulnerabilities if I modify the SBSFU to send its TRACE messages to an SD ...
Hi,We are currently using an stm32l5 in our product and experimenting with a stm32L562E-dk and with the official TFM (https://git.trustedfirmware.org/TF-M/trusted-firmware-m.git master branch on the latest commit at this date.) The TFM is unmodified...
Hi everyone.I am working on SMBus communication and i want to calculate PEC (packet error code) value. PEC value is using CRC-8 checksum with 0x07 polynomial. I want to use CRC peripheral in STM32G031F6 for PEC calculate. Cubemx settings are below.An...
I already used tamper detection mechanism, now I want to use it with Trustzone activated, I configured the tamper as non secure first and it works, but when I tried to configure it as secure, it didn't work, and I couldn't detect the tamper, we know ...
Actually, I'm trying to use passive tamper detection with trustzone activated in stm32U5. I'm using pushbutton to simulate the tamper and I want to to toggle an LED as a response, it works when I configure the tamper as non-secure, and the LED is con...
