Hello,is there any example of a TFM application that is supported by STM32CubeIDE?I came across the iot-reference-stm32u5, but the structure of the project is way different from any other TrustZone and TFM examples available as part of the STM32CubeU...
Hi,I want to compute APP's hash (SHA256) from my Bootloader using DMA.I have 3 non adjacent zone to process the HASH.If I use one node and call HAL_HASHEx_SHA256_Start_DMA inside HAL_HASH_InCpltCallback, I can compute my HASH.I hope I can use link li...
Hey guys, how are you?It's been a long time that i'm facing a issue with STM32WB CPU2, most of the times i just fix it without really knowing the cause of it. Basically what happens is after power-up CPU2 simply won't initialize on the first try. I h...
Dear Team,I want use inbuild AES encryption engine to encrypt the data, therefore I used CubeMX to initialize the AES engine, when i'm going to encrypt the payload, it stuck in static HAL_StatusTypeDef CRYP_WaitOnOFNEFlag(CRYP_HandleTypeDef *hcryp,...

The STM32H753 has 2 CRCs. One global CRC and one specific for Flash memory.I think it is possible to use the global CRC for flash memory right ? The benefit would be to use a different polynom than the one from Flash CRC.is it possible to have an ide...
Hello,I am working on an IoT security project, where a TPM like STSAFE-A110 is required for signature verification and data decryption. The latter fails with the mentioned chip and the static (non-ephemeral) private key.Setup:X-NUCLEO-SAFEA1 board (w...
Hello,I am trying to start a debug session with STM32CubeIDE v1.11.2 on my board locked on RDP 0.5.I loaded a valid secure firmware which jumps into the non-secure firmware before setting RDP 0.5.I could connect STM32CubeProgrammmer and flash the non...
Hey guys, I want to perform a firmware upgrade over the air. And use a UART to connect to IoT device.I use stm32l431xx and it contains hardware for symmetric encryption. And the host device which sends the binary uses stm32l496 has SBSFU.So I have a ...
STM32 Trusted Package Creator v2.12.0 creates incorrect option bytes which have 8 rows and no "reserved" last row As per AN5054, it should have exactly 9 rows The option bytes csv created from STPC v2.12 This leads to SFI programming failure. Am I mi...
