I am using the SBSFU example of "NUCLEO-L552ZE-Q" Projects.I have added my application code to the NON-Secure application project.When I see "Region_defs.h", in which nonsecure (NS_TOTAL_RAM_SIZE ) size is 192 KB whereas secure (S_TOTAL_RAM_SIZE)size...
I was searching for the security features of STM32F769I - DISCO and came to know that only STM32F77x has CRYP and HASH in the STM32F7xx series.Do STM32F769I - DISCO really have security features? If so, can you provide a relevant document regarding t...
While programming OptionBytes or FW on STM32WLx5 most of the time is OK.In CubeProg I have noticed, that on some MCUs, when I get reading of RDP 0xFF or 0, the next action to program something write related, it could not be done and it's failed.Stati...
hi all,I would like to experiment with the TFM applications contained in the STM32CubeU5 package on my B-U585I-IOT02A boardunfortunately, it seems that STM32CubeIDE is not supporteddoes anyone have suggestions on how to build the TFM applications, ba...
Hey, I went through the manual of the STM Programmer command line interface and implemented a post build CRC calc with the Safety lib command -sl.C:\PROGRA~1\STMicroelectronics\STM32Cube\STM32CubeProgrammer\bin\STM32_Programmer_CLI.exe -sl MESOL_CAN_...
I am building a custom loader for SBSFU on the STM32WB5MMG. The loader is similar to the BLE_Ota loader, but instead of using BLE, it loads firmware/wireless stack from an onboard microSD card, as well as being able to write CKS keys.I do need to hav...
As I understand OTFDEC will be used to on-fly decryption, while execution (am I correct)?After debug is fused (RDP set to level 2) all DHUK keys are individual for each device, while during debug phase all keys are common. How can I make test run of ...
I set my flash OB to iROT-Provisioned (Dont know exactly Product life cycle state, but I can not debug anymore) Based on my understanding, it may be in a CLOSED state. However, I am not sure how to change the state as I want to follow the Debug authe...
Currently, my program cannot be executed, and it is useless to pull up the boot pin, and STLink cannot be linked. There is a way to reset the chip register boot_lock, TZNE, and RDP? or how to perform full chip erasure?
