Hi,My custom SBSFU_UserApp.bin failed the header signature verification in slot SLOT_ACTIVE_1 when I tried to execute it on the STM32H7B3I-DK board.To replace ECDSA with RSA signing verification, I have changed se_crypto_bootloader.c.SECoreBin projec...
Referring to "mapping_sbsfu.h" file of the example "2_Images_OSC" of STM32f769I-Discovery, seems the DTCM and SRAM2 are not used in the project.So does it have a reason?
I tried to make my project SBSFU compatible, by using 'STM32F769I_Discovery_2_Images_UserApp' example. It is based on the STM32F756VGT6 microcontroller and I defined the load region on ITCM interface address range -0x200000 to 0x2FFFFF- instead of AX...
Hello,I try to verify data with cmox_ecdsa_verify. It fails with CMOX_ECC_ERR_BAD_PARAMETERS. I think my public key has the wrong format, because the buffer CMOX_ECC_SECP384R1_PUBKEY_LEN is 96. My key has the length of 120 bytes.I have exported my pu...
1. I need to implement SBSFU (Secure Boot and Secure Firmware Update) in my Nucleo STM32H743ZI Board, but the SBSFU package is available for STM32H753ZI, STM32H7B3I-DK, STM32H750B-DK board. So Which Package is best for the Nucleo STM32H743ZI board...
Hello,I am trying to flashing customized SBSFU_UserApp.bin of 1_Image application from BSFU example project on STM32H7B3I-DK. I am getting error when the application is booting. The error is:= [SBOOT] SECURE ENGINE INITIALIZATION SUCCESSFUL= [SBOOT] ...
