Hello,I've added the OEM2KEY AND OEM1KEY to the RDP Level 2 protection in order to perform the same steps as in the 'Getting started with STM32CubeU5 TFM application' for enabling Production Mode.Following the steps and executing the HARDENING.SH fil...
Hi,[EDIT 3] there is no need to configure GPIOC pin 0,1 and 2 as secure to be used by ADC1 since all GPIO are secure by default when TZEN = 1. cf. RM0456 § 3.5.6 "activating TrustZone security". This is why you do not find an of this in generated cod...
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...
Hello ST Community,I'm currently working on a project using the STM32WB55 MCU and am in the process of implementing Secure Boot and Secure Firmware Update (SBSFU) in my custom application. As part of this, I decided to test the existing 1_Image_SBSFU...
Hi ,i am using STM32L4R9 based dev board STLINK-V3MINIE and wanted to use SBSFU, used the example code STM32L432KC_Nucleo_1_image from the library and flashed the SECoreBIN followed by SBSFU and then the userAPP code, but while flashing userAPP ,i go...
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
We managed to successfully run TFM_SBSFU example for the IOT02A board. We are using latest STM32Cube_FW_U5_V1.2.0.The problem is that we do not have access to PSRAM from NonSecure application when in memory mapped mode.We implemented PSRAM init by im...
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 ...
