Resolved! Unable to reallocate Application at other than base address
I aim to load my application at 0x08002000 instead of 0x08000000(base address) and secure the first two sections which will be used to store CRC and other firmware update information.I use a post-build script to calculate the CRC using srecord utilit...
Error in STM32H753 reference manual related to AES-GCM ?
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
AES encryption in STM32F407VT06
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.
STM32H743 calculates different values for SPI CRC depending on SPI instance
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...
Resolved! B-U585I-IOT02A TFM Application in STM32CubeIDE?
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...
STM32U585 : HASH DMA fail with multiple node in linklist : GPDMA never enter in IRQ.
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...
AES encryption not working
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,...
Hello, I am trying to implement the HKDF algorithm to generate a secret key, and I found a link containing an example of HKDF implementation ( you will find link below in details) but unfortunately, the code is incomplete and I have a few questions.
