Hi,Our product proposal to a client has at the root of its security an STM32H533 running our OEM Bootloader and Secure Application only. The Product State will be either Closed or Locked (as yet undecided) and we will be storing encryption keys used...
I have the NUCLEO-H753ZI example running on my board. All works fine without the security features. When I enable both the SFU_MPU_PROTECT_ENABLE and SFU_IWDG_PROTECT_ENABLE. I keep having a watchdog when it tries to execute the firmware. I commented...
I am using a stm32l451cet6 micro controller chip in my PCB. I want to make the flash memory read protected. For this I use the following code snippet - while (HAL_FLASH_Unlock() != HAL_OK) { ; } ...
Hello,i'm using stm32h747igt6 microcontroller, it has two cores Arm Cortex-M7 + Cortex-M4, i'm currently working on core m7, and i have integrated STM32 cryptographic firmware library software expansion for STM32Cube for some security features in my ...
Hello all, We are working on STM32 Secure bootloader for STM32H7B3RIT6 MCU.For this we taken reference code from X-CUBE-SBSFU STM32H7B3I-DK .As of now we have successfully migrated the SBSFU & SECORE code for STM32H7B3I-DK to Our MCU.We have prepared...
Hi,I try to use the SBSFU in a project with a STM32F722 and so far it works to flash an initial firmware. Now what I would like to do is to update the firmware and for that, since I can only use one image because of the limited flash size, I corrupt ...
Hi, I have enabled the HASH, RNG, and PKA. I also enabled the Global Trust Zone Controller and configured the PKA as privilege access. However, the generated code from STM32CubeMX does produce an error due to undefined GTZC_CFGR3_PKA_Pos which is mis...
Does ST offer an implementation of hardware acceleration of mbedtls-2021?I found this:STM32CubeL5\Projects\STM32L562E-DK\Applications\TFM\TFM_Appli\Secure\Src\ecdsa_alt.cSTM32CubeL5\Projects\STM32L562E-DK\Applications\TFM\TFM_Appli\Secure\Src\ecdsa_c...
Hello everyone,i am trying the secure user memory on the stm32h7b3 using the examples provided by ST. In want to enable secure user memory for a 230KB area starting from the begin of the flash: 0x08000000. The function RSS_API->resetAndInitializeSecu...
Hi,I'm currently exploring the solutions to develop a bootloader on a STM32U535. I'm looking into the MCUBoot based examples provided by ST : SBSFU projects.After some investigations, I noticed that the SBSFU_Boot memory footprint was ~80ko and the S...
