Hello,I am trying to do a proof-of-concept running the Apache NuttX RTOS on the ST32L562E-DK board as the non-secure application with TrustedFirmware-M.I can build, sign and flash NuttX as the non-secure application and TF-M boots into the RTOS initi...
Hello,I want to use sbsfu for STM32L562 controller with STM32Cube IDE version 1.5.AS per primary research i am using below package and project .I am using STM32SecuWS package.Under that project I am using is STM32SecuWS\TFM\STM32Cube_FW_L5_V1.3.0\Pr...
Hi,I've been trying to port the STM32H753 SBSFU project to the STM32H735G-DK.The bootloader fails in SFU_BOOT_Init due to failing SE_Init().This is the result of __IS_SFU_RESERVED() failing it's test: 0x08008A00 < 0x08008061 < 0x0801FFFF (SB_REGION_R...
I would like to use the RNG of the H743ZI2. The provided example works, but on a new project I can't get it work, The CPU clock is configured to 400MHz just like in the example./* RNG Initialization */ if (HAL_RNG_DeInit(&hrng) != HAL_OK) { /* ...
I want to apply Read Protection to the STM32L552CCT6 .If you execute HAL_FLASH_OB_Launch(); after setting Read Protection, reboot does not work.Read Protection is applied only when the power is physically rebooted.I want Read Protection to be appli...
Background:I am working on a project that uses the STM32H7B0 processor on a custom board. The firmware is loaded by ST SBSFU bootloader STM32CubeExpansion_SBSFU_V2.4.0. I have used 2_Images_ExtFlash example as a template, and our firmware is stored a...
HiWhat is the maximum Stack and Heap size of a STM32G474VE with the SBSFU Bootloader 2 Image version?In the icf file the settings are at 0x400 and 0x200 which is really low./*-Sizes-*/ define symbol __ICFEDIT_size_cstack__ = 0x400; define symbol __IC...
Hi,In static HAL_StatusTypeDef CRYP_TDES_Process(CRYP_HandleTypeDef *hcryp, uint32_t Timeout){ uint32_t temp; /* Temporary CrypOutBuff */ uint16_t incount; /* Temporary CrypInCount Value */ uint16_t outcount; /* Temporary CrypOutCount Value */ /* En...
The STM32H733VGH6 datasheet specifically mentions "Bootloader with security services support (SFI and SB-SFU)," while the STM32H723VGH6 does not. Does that mean that I can't use encrypted firmware on the STM32H723VGH6?I tried to do some research, but...
