Hi All,I am almost finished integrating the SBSFU into my project. I can run the SBSFU and user app and update the processor, STM32L4R9VITx, successfully while no protections are enabled. When I enable firewall protection it boots into my application...
Hello,I want to use the security features included in the TFM in my application, I have followed UM2851, now,I have a better understanding for TFM and I succeed to implement it in STM32U585, to go further I want ot implement my own non-secure applica...
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...
