How to program stm32L552 using SWD interface
I use my own application to program different devices, arm in particular. Now, i'd like to support stm32L552. So, if TZEN = 0 it works fine. if TZEN = 1, DBANK = 1, SECWM1_PSTRT - set as secure, SECWM2_PSTRT - set as non-secure, RDP = 0xaa (level 0) ...
Enabling SFU_MPU_PROTECT_ENABLE causes a problem
In my project the microcontroller is STM32F756VGT6, I changed the example "2_Images_OSC" of STM32f769I-Discovery to be compatible with this microcontroller.Right now everything seems O.K and I can upgrade the application with SBSFU. But when I uncom...
Catching and clearing BusFaults in STM32 H743
We are having issues with corrupted flash on the STM32 H7 series. The problem manifests where a read to the offending address in flash will cause a bus fault. We think it is down to bad CRC and the way to resolve is usually to wipe the flash and repr...
Resolved! How to enable debugging of SECoreBin application
Hi,I tried to execute my custom SBSFU_UserApp.bin on the STM32H7B3I-DK board and I get error for Header signature verification failure in slot SLOT_ACTIVE_1. I have made changes in se_crypto_bootloader.c file for adding RSA signing verification in pl...
WRITE_REG macro not working
I'm currently trying to use the CRC peripheral on an STM32G474, and when running HAL_CRC_Calculate(), the computed checksum is always zero. Doing some debugging into the HAL_CRC_Init() function, I've found that when the WRITE_REG macro is called, no...
STM32Cube_FW_WL_V1.2.0, application LoRaWAN_SBSFU_1_Slot_DualCore. Bug in the MPU configurations??? (file .\2_Images_SBSFU\CM4\Inc\sfu_low_level_security.h)
I'm creating a new lora project starting from STM32Cube_FW_WL_V1.2.0, application LoRaWAN_SBSFU_1_Slot_DualCore.I reserved some space (from 0x0801A000 to 0x0801BFFF) for some configurations. I modified the file mapping_fwimg.ld like below.\STM32Cube...
For the Cortex M-33 products can I use my own RNG?
This is a general question on the Cortex M33 product with hardware encryption. I would like to use my own random number generator rather that the one that is embedded with the core in order to generate my AES key(s). Is that possible or am I restri...
Cryptographic hardware acceleration libraries for STM32F423
I have download the TM32CubeExpansion_Crypto_V4.0.1 library. The folder structure doesn't look like the one represented in the UM1924 document. There is no AccHw_Crypto folder and no STMF1 to STMF4 folders nowhere.Is there support for AES HW accelera...
How does secure boot of STM32 work?
Does it have hardware ROM for keys and certificates?Can you bypass it by boot from USB?What is the crypto hardware?Is there a detailed block diagram?
