I've found an inconsistency between different reference manuals of STM32 embedding the CRYP peripheral, about the management of IVs in GCM mode:The HAL seems to implement the second solution.Could you confirm ?Best regards
Hi All,Did Someone use AES encryption/Decryption in STM32F407?, because I'm using existing example of AES encryption and its not working on my board, EN bit isn't enableing.
Hello to all,I am using a STM32H743 and create a SPI master (SPI4) and a SPI slave (SPI2). I have connected the pins used (including NSS). For receiving and transmitting I use DMA in both parts, master and slave. The configuration was done with STM32...
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...
