Hi, I've been working on porting the SBSFU onto a STM32H7A series with my custom gcc-arm build environment.The example project I am referring to is: x-cube-sbsfu-v2-7-0\STM32CubeExpansion_SBSFU_V2.7.0\Projects\STM32H7B3I-DK\Applications\2_Images.Ever...
This works fine in an app without SM but when I run this from a non-secure app together with SM, the last step fails. This is the code: // Enable access to RTC and backup domain HAL_PWR_EnableBkUpAccess(); if (__HAL_RCC_GET_FLAG(RCC_FLAG_LSERDY...
Hi, I'm using 3 channels of ADC4 with GPDMA1 (channel 4) in secure world of a TrustZone-project and the DMA-buffer stays always 0. The same ADC/DMA-configuration with the same application code (all mnus the security aspects) are working fine without ...
Hello. I am experimenting with securing a STM32H503 using password authentication, which will ultimately be an automated process.I created a simple password for testing and created the password hash in board_password.bin and da_password.bin(just for...
HelloWe are considering STM32 based processor for our next generation of products and would like to talk to a security expert with ST to discuss achieving CRA compliance.The "contact" page on the website down not provide a way to contact ST in the UK...
TL;DR:On STM32G0B1 with SBSFU + SECoreBin, I want to design a secure crypto/key enclave for the user APP.Enclave should be WRP/PCROP/MPU protected.Only accessible via SVC/gateway from the unprivileged APP.Should remain updateable through SBSFU (incl...
The reference manual mentions that data swapping can be used when e.g. processing ASCII, but I'm not clear on exactly what it does. If I set it to byte mode, does that mean I can write single byte values padded to 32 bits with zeros into the FIFO? An...
Hi,I'm using a STM32H743II.The product will communicate to server using the LwIP (TCP Layer) + MbedTLS (SSL/TLS Layer), running over FreeRTOS environment.We want to use the latest TLS protocol standard (TLS Version 1.3).We are currently using MbedTLS...
Hello @Jocelyn RICARD , @D.Botelho I am trying to enable debug authentication on a stm32h573 mcu following this example: https://community.st.com/t5/stm32-mcus/how-to-enable-rdp-like-product-state-flash-protection-in-stm32h5/ta-p/708082.I was able to...
Hello!I am trying to provision a DA certificate on STM32H563 through CANFD Bootloader in system memory.I am calling special function 0x83 as described in AN2606 and AN5405. As I can understand, this is an RSSLIB_PFUNC->DataProvisioning.I am filling t...
