Hello,I am currently using STM32L010 MCU in my application where we have UART and SWD lines exposed to be accessed only by service personnel (under a cover but still accessible without dismantling the device). Since we want to have a possibility to p...
Hello, I would like to set the RDP LEVEL for my stm32l0 MCU without using ST link utility software, to be more specific, how I can set the level in the firmware to be flashed in which area ? and is it possible to add a script to linker to set the ...
Dear,I am setting RDP to level 1 in my application, After setting it I call System reset HAL_NVIC_SystemReset(); After reset I am expecting the MCU is locked, but it seems I read in code the MCU is still in level 0 so the procedure of setting RDP to ...
Good day everyone,I'm looking for STM32L082 code examples to use its AES peripheral.Does anyone have something that could help? I had alread searched the internet, but could not find code examples anywhere.I'll be greatful if anyone could shed some l...
RNG, CRC, and DMA are all peripherals on the STM32L08x AHB bus. If I try to write to CRC_INIT before enabling CRC clock in RCC then STM32-WorkBench Memory window correctly just shows zeroes. But after enabling CRC clock in RCC_AHBENR and writing to C...
Hello all. I am using stm32L071CBTx and I need to implement crypto here. I am using official crypto library(UM1924). I have managed to run the code with my hardware. Th problem I am facing here is that whenever I change plainText values, it doesn't w...
My question is about intellectual property theft at CMs. Clearly ST recognizes the issue and even addresses it by adding SFI (secure internal firmware install) on some microcontrollers. AN5054 is listed in the resources for STM32L010K4; however, it i...
Hi all,I generated code in STM32CubeMX for STM32L081CBTx controller with AES enabled.I built the generated code (without modification) in STM32CubeIDE, but it failed with warning:../Core/Src/stm32l0xx_hal_msp.c: In function 'HAL_CRYP_MspInit': ../Cor...
Hi ST community,I have a fully functional application on my STM32L072. The problem is when I tried to enable RDP, nothing works anymore.After flashing the application I tried to connect with ST-Link, the option bytes are set correctly and it is not p...
I started a new project, and my security requirement states that user authentication is required when updating firmware.I wonder if there's a feature for this, and if not, can the bootload side be modified to meet this requirement?I searched and foun...
