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...
HelloIn chapter 22.4.9 of RM0434 Rev6 is stated:Counter: a 32-bit big-endian integer that is incremented each time a blockprocessing is completed. The initial value of the counter must be set to 1.Why can be the initial value of the counter not be se...
Hi All,I am using SBSFU to load my firmware which is running from external flash. The firmware works but seem to be experiencing speed issues on the I2C communications.In an attempt to solve this issue, I am would like to, at start-up copy the code t...
Hi,I find the new chip STM32G0B1 from STM32CubeMX.And I want use this chip with SBSFU 2_Images.But I can not find the STM32G0B1 project from the X-CUBE-SBSFU v2.4.0.Is STM32G0B1 compatible with X-CUBE-SBSFU v2.4.0 ?How do I use STM32G0B1 with SBSFU 2...
During the workshop itself, I had some problems with some of the example files not having correct access rights to allow the workshop changes to be made.We worked around that during the workshop.Now I have just come back to the STM32Cube IDE; it star...
HelloThe crypto HAL driver ( function CRYP_SetKey in file stm32wbxx_hal_cryp.c ) of the STM32WB accesses the key as "array of uint32_t" (lines 2919 etc): hcryp->Instance->KEYR3 = *(uint32_t *)(hcryp->Init.pKey); hcryp->Instance->KEYR2 = *...
I converted code from one of the example from sbsfu for stwinkt1 board.This converted example is for 2 image and working fine on serial port.As far as i get for 2 image example configuration will like,SBSFU s;ot+1 active slot + 1 DWL slot + swap area...
I have some code that removes a "secure area" on STM32H75x by so called "regression" from RDP level 1 to level 0, which causes full erase.(Actually this code is based on example very kindly provided by ST support) void EraseAll(void) { uint32_t fla...
I am trying to create a mechanism of verification where I sign a file on the PC save it to a disk on a key device and then verify it by the MCU after saving it to internal flash.The PC is doing the signing process and the MCU should only do the verif...
