Resolved! is RDP LEVEL 1 Enough?
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...
Resolved! STM32H7B0VBT6 External Loader
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...
Unprotect Flash to write a new Bootloader
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...
HAL_CRYPEx_AES() maximum number of output bytes?
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...
X-CUBE-CRYPTOLIB cmox_eddsa_verify memory fail
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. ...
SBSFU not detecting Active Slot Image
I'm working on integrating the latest SBSFU (v2.6.2) onto an STM32L4A6 platform. I've reviewed both the user manual and application note for the SBSFU, as well as the examples provided.In my use case:I have an external attached MMC flashI'm not plann...
