We have a project where we're using a U5A5 MCU with trustzone enabled and we're currently trying to figure out how to flash without having to use the SAM card. I downloaded the example from ST and am trying to run through the B-U585I-IOT02A TFM exam...
I am implementing encryption and decryption using AES-GCM mode on the STM32 NUCLEO-U5A5ZJ-Q. I have successfully encrypted and decrypted the string "Hello", but I am having issues with tag authentication.I am using the function HAL_CRYPEx_AESGCM_Gene...
Hello community,I need to use the AES-CMAC functionality of the STM32L562QE.The datasheet says that it is supported :But it seems that the reference manual doesn't say anything about CMAC functionality.Is there really a way to use the AES coprocessor...
Hi ,I can find AES DPA in TFM demo application, but can't find TDES DPA implementation in TFM.Please advise how to implement TDES DPA.
My H5 DK board is in TZ-CLOSED state (after --sfi-flash), I am unable to put it in "Level 1/2/3 Intrusive Debug" state no matter what combinations of keys and certificates to use (including key_1_root.pem and cert_root.b64). Only Full regression work...
Hello everyone,Now I'm developing an user application compatible with SBSFU on STM32CubeIDE.SBSFU itself is pretty nice, but I feel the development architecture and environment are a little bit old, like not supporting CubeMX.Fortunatelly, I succeede...
Hello,I try to implement a tamper detection for my project. In general, it works. When the device is only powered by a coin cell and a tamper is detected, the backup registers are erased and unfortunately also the backup RAM. When the device is power...
Hi,I ported the SBSFU project to the LoRaWAN_AT_Slave routine, and tested DFU normally and it worked fine, but when I used the wrong file to upgrade, such as readme.txt, the upgrade process ran for a while, and then stopped, showed " Fw header authen...
Hi,I ported example projects from en.x-cube-safea1\project\NUCLEO-L476RG for MbedTLS cryptolib for use on my B-U585I-IOT02A Discovery Kit. The STSAFE-A110 is powered correctly and NRESET is pulled high. It never errors on writes to the device, but al...
Hi All,I am following the UM2262 document. I will add a screenshot. I enabled the ENABLE_IMAGE_STATE_HANDLING flag to enable rollback, but after updating UserApp.bin, the device continues to reset. I will add a debug log screenshot (it’s not jumping ...
