Ask questions and find answers on STM32 security frameworks and tools, including cryptographic libraries, TrustZone, and the Secure Manager.
In some ST documents the STM32L0X1 is listed as having an RNG peripheral and older versions of the CMSIS headers list the RNG register addresses. Moreover, enabling the peripheral and using it appears to generate random numbers. However newer manual...
Hi,I'm using some STM32 drivers code to parse X509 certificates. These drivers are based on ECC cryptography. I need to change to RSA. I need utilities such as parseCert()isValidCert()isParent()which exist for ECC, but I cannot find any equivalents f...
Looking for the MCU specs with the following key requirements: - 24 IO : 8 input, 8 outpt, 8 x LEDs - secure boot features - hardware reset - backline support – CAN Bus communication at 5VCan STM32G...
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) ...
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...
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...
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...
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...
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...
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...
