Hi there, I'm new to the STM32 MCU and simulating RSA encryption-decryption on Proteus 8 now. Currently I am using the x-cube-crypto and STM32F401RE-Nucleo to do simulation. The source code is from:nickfox-taterliIn the Proteus 8 I chose a board of S...
hi St team, thank you for your support.My objective is secure boot for my independent project. i am using stm32L562vet i am able enable trust zone with RDP level =1 and able to disable the trust zone using RDP regression. now i want to implemen...
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...
