Hello,i'm using stm32h747igt6 microcontroller, it has two cores Arm Cortex-M7 + Cortex-M4, i'm currently working on core m7, and i have integrated STM32 cryptographic firmware library software expansion for STM32Cube for some security features in my ...
STM32 Secure Boot
Hello all, We are working on STM32 Secure bootloader for STM32H7B3RIT6 MCU.For this we taken reference code from X-CUBE-SBSFU STM32H7B3I-DK .As of now we have successfully migrated the SBSFU & SECORE code for STM32H7B3I-DK to Our MCU.We have prepared...
SBSFU - flash erase 0x0000 instead of 0xFFFF
Hi,I try to use the SBSFU in a project with a STM32F722 and so far it works to flash an initial firmware. Now what I would like to do is to update the firmware and for that, since I can only use one image because of the limited flash size, I corrupt ...
Resolved! GTZC and PKA privileged config
Hi, I have enabled the HASH, RNG, and PKA. I also enabled the Global Trust Zone Controller and configured the PKA as privilege access. However, the generated code from STM32CubeMX does produce an error due to undefined GTZC_CFGR3_PKA_Pos which is mis...
