Hi @Jocelyn RICARD Greetingswe are trying to run TFM example (with secure and non secure project) taken from GPIO_Toggle_TZEN Example and adding SPI communication in the non secure project on our custom board mounted with STM32U585aii6q controller SP...
Hello,I'm trying to figure out how to properly use STM32WB55 PKA registers for RSA key generation and encryption/decryption. I have chosen small (63 bit) primes for generating RSA private key, which worked perfectly. However, I am having trouble with...
Hi all,we are developing a product with the STM32H573. The idea is to use the STiRoT for secure firmware update. The MCU is connected to a Linux CPU via SPI. Now we plan to do the provisioning during the production using the Linux CPU that has a ethr...
Hi,I have read datasheet of STM32F103VCT6, it does not mention anything about code read out protection. Does STM32F103VCT6 has this function? (a security function to protect STM32F103VCT6 from reverse engineering)Thank youDavid Kean
Hi, I've decided to create a new post based on the similar one (https://community.st.com/t5/stm32-mcus-security/solved-stm32u5-tfm-example-b-u585i-iot02a-memory-mapped-psram/td-p/108722) which has been solved but doesn't work for me.The problem is as...
Hello,I am using STM32H750 and X-Cube-Crypto lib. I am working on a secure boot and want to calculate the app Hash value to check integrity. The library works fine for STM32L5 Mcu (Already tested) but not with STM32H750. I verified that I am using th...
When generating a new project for an STM32H573RIT6 MCU with Trustzone enabled and boot path STiROT -> STuROT -> non secure app, I get this warning:"The provisioning scripts are only supported for DK boards (Or custom boards with the same flash and sa...
Reference: STM32CubeExpansion_Crypto_V4..1.0, MCU: STM32G474REThe cmox_ecdsa_verify(...) function is failing with a fault code of 0x6c706, which is not contained within cmox_ecc_retvals.h header file. All arguments to the cmox_ecdsa_verify(...) funct...
Hello,I have done a big mistake. I was testing a provisioning using the system bootloader. For that I have changed the provisioning batch files. As a result I have set the product state to closed, before the keys where loaded. Now I can not connect ...
I am using USB peripheral on the STM32U5 with TrustZone enabled. I met a problem. In Non-Secure area, USB_DRD_FS->CNTR, USB_DRD_FS->CHEP0R can be set correctly. In Secure area, I can set "USB_DRD_FS->CNTR = 0x9D00;".But I can not set the "USB_DRD_FS-...
