I am using TFM-SBSFU example provided in STM32L5.Secure Area 1 which is already configured as below.When I am trying to read 0x8012000 from non-secure application, I am getting secure fault. I want to add one Partition 0x807d000 of 4KB into secure a...
Using STM32L452CC and STM32CubeProgrammer API v2.12.0 Windows 64-bits.Firstly, I'm setting the readout protection to its middle level (RDP = BB in the programmer) and then program the chip successfully. Then, letting the chip power cycle. Now reading...
Hi,I am currently trying to change RDP level via firmware without a power reset (POR) on a NUCLEO-WB55RG (STM32WB55). I am facing the problem that after changing the RDP level a power reset is necessary. Without a power reset the device seems to get ...

I complie STM32F769I-Discovery 2_Images demo (SBSFU\Projects\STM32F769I-Discovery\Applications\2_Images\2_Images_UserApp\MDK-ARM) with MDK KEIL 3.37.If I link project using default UserApp.sct, the packed image is right, and output.txt show below:blo...
Hello,We have a software project with STM32H7B3 MCU using SBSFU for bootloader and installing updates. We are using one download slot and one active slot and have been very tight on flash size and have often had to reduce binary size. Normally, this ...
When I set the RDP Level 1 the Controller stops working.I must unpower the Controller and power it agin, NRST didn't work.I use the code: HAL_FLASH_Unlock(); HAL_FLASH_OB_Unlock(); OBIni.OptionType = OPTIONBYTE_RDP; OBIni.RDPL...
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...
