Hello,HAL driver for CRYP peripheral of STM32H7RSxx series generates invalid AES GCM TAG.According specs, header should be 0-padded to 16 bytes, but in the function CRYP_GCMCCM_SetHeaderPhase() the HeaderSize field is assumed to be expressed in words...
Hi,I am using the STM32H7S78-DK. I want to upload an encrypted application to the external 1-Gbit Octo-SPI flash memory connected to XSPI2.I am using the explanation in this video: https://www.youtube.com/watch?v=JxhKmVUB2Ws&list=PLnMKNibPkDnFQXYK0zt...
Hello ST team,I am currently working on NUCLEO-N657X0-Q (STM32N6) device using a FSBL (Secure Bootloader) an APPSecure and an AppNS (Non-Secure Application).The FSBL is correctly loaded first and then jumps to the AppSecure which jumps to the AppNS. ...
Hi all, I am trying to make my NUCLEO N657X0 board working with : FSBLAPPSecureAppNonSecure I am having issue in understanding how to get the things done : I have created a new STM32 project on STM32CubeIDE, ending with having 4 differents project...
hi, I'm using stmf103c8T6. Recently it got RDP enabled while trying to flash a program. ever since then I'm not able to connect through cube programmer or cube ide. I tried to mass erase and write RDP=0xaa through stm programmer cli. all though I'm g...
Hi, we are developping a projet with TFM activated on STM32U585 device (by the way, we don't really need the full TFM but at least Secure boot and SBSFU). We would want to declare a Flash page to store some configurations parameters, so we created a ...
Need assistance on generation of the ECC key pair using crypto library. Can you guide on how to link the required .a files to the project tool (IAR embedded workbench) so that the function declarations present in .h files without .c files will execut...

STM32U585 When TrustZone is enabled, X-CUBE-CRYPTOLIB produces incorrect SHA256 hash values.Additionally, mbedTLS generates incorrect public keys when creating ECDSA key pairs, and this issue is 100% reproducible.Neither hardware acceleration is enab...
HiI have a design using STM32H523 and I've managed to ensure that my firmware switches PRODUCT_STATE to 'Closed', and sets a valid debug password, the first time it runs. This works well.In the Flash I have a bootloader, application, and configuratio...
