I get a stm32l562e-dk board, when I use the following figure setting to connect to the board and modify nSWBOOT0 bit to 0(TZEN=1). I found that I can not connect to the board using "Hot plug" or "Normal" mode.whether I FOREVER lost the device? In ad...
Hello,I’m working on a project using the STM32WLxx MCU and need guidance on implementing asymmetric cryptography (encryption, decryption, and key management). The MCU supports AES for symmetric encryption, but I’m looking for a solution for asymmetri...
Hi,I am working on SBSFU with stm32L476 Nucleo Board I am following the steps of Tutorial Security Part6 - STM32 security ecosystem - 02 Building the SBSFUI have Download Stm32CubeExpansion_SBFU_V2.6 but which is the highlighted directory are missing...
Where can I make the Encryption Option "Disable"?
hiplease only ST Employee answer this questioni use this code for enable RDP LEVEL 1 for STM32H743 and STM32F407Can this code alone protect the program in the flash from any type of attack to read the program in the microcontroller?Will it be possi...
I am using the STM32H7B0VBT6 microcontroller, which has limited internal flash memory. To implement Secure Boot and Secure Firmware Update (SBSFU), I have connected an external W25Q256JVIQ flash memory to the MCU via Quad SPI. Is it possible to sto...
Hello,I am trying to use below file to enable RDP 2 on an STM32 L552 controller.wiki.segger.com/images/7/78/STM32L5_Lock.jflash This has exit step "ExitStep21_Action" that set the DRP Level 1, However, I need to set RDP Level 2 by setting the value a...
I'm using a STM32F103RCT6Flash contains my own boot loader in pages 0 thru 10 and main application in 11 thru 61.When the device is flashed in manufacturing, protection is set to prevent reading and writing via the jtag port.I need to update the boot...
I am using an STM32L4S9ZIJX part and attempting to encrypt a 256KB buffer (actually 262,144 - 16 = 262,128 bytes) using AES256 CTR mode in polling mode.I created a wrapper function to perform the encryption: int encrypt_CTR_mode(uint8_t* key, uint8_t...
Hi everyone!In our project for stm32f446, we are trying to use X-CUBE-CRYPTOLIB to verify the firmware signature on the device using ED25519. Unfortunately, when trying to call the cmox_eddsa_verify method, we get the CMOX_ECC_ERR_MEMORY_FAIL error. ...
