Hi, I have managed to extract the OEMiROT project from H533 into H523 and compiled it successfully using STM32CRYPTO library since H523 does only have limited cryptography accelerator. I have modified the flash_layout.h to match my application (which...

Hi, I have locked out my MCU. I generated a Debug Authentication file with certificate (DA_Config.obk) and provisioned that into the MCU. However, I think I have regenerated a private key without regenerating a certificate. I am no longer able to do ...

Hi, I am working on OEMiROT bootloader for STM32H523. I have copied big parts of the ST OEMiROT example project from H533 example as this is the closest MCU to H523 from the flash memory layout perspectives. However, it is taking ridiculously too lon...

Hi,I am using STM32CubeMX version 6.13.0.I have created my own folders inside Middlewares folder. After each code regeneration, my own folders are deleted automatically. This issue is linked to the previous thread https://community.st.com/t5/stm32cub...

Hi, I have tried to configure the STM32H523RET6 for using USART1 with multiprocessor communication mode and enabled the auto baudrate detection. However, according to the application Note AN4908, the MCU stm32h523 doesn't support auto-baudrate. I don...

Hi, I have fixed the issue. The flash memory layout related macros in the image_macros_processed_bl2.c were not matching the defs in flash_layout.h and thus the script error out. I made sure that the defs in image_macros_processed_bl2.c are compatibl...

Hi @Jocelyn RICARD I would like to follow-up with you regarding my question on un-breaking the STM32H523 MCU I would be appreciated to know if it is possible to activate the system bootloader somehow or reconfigure the option bytes and convert the MC...

Hi @Jocelyn RICARD I also would like to ask:When regenerating private key, under OBkey generation in TPC, does it regenerate the private key based on the original public key? Or Is it the best practice to regenerate the private key via another method...

Hi @Jocelyn RICARD , Thank you so much for the clarification. I guess this was part of my learning process with STM32 security :) Ok, Can I hold BOOT0 to High while reseting the MCU to force the originally downloaded STM bootloader is system flash me...

Hello @Jocelyn RICARD, I can't even connect the MCU as it is product state is CLOSED. I tried to regenerate certificates from all of the private root keys I generated but nothing works to regress the MCU. How would I add the regression in my firmware...
