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...
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...
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-...
I do have the document UM2262 which describes the SBSFU expansion package, but it only gives a fairly brief explanation of the prepareimage tool.
Hi Team,I hope this email finds you well. I am reaching out to inquire about documentation similar to UM2262 but specific to the STM32H5 microcontroller.We are currently working on a project that involves firmware encryption, decryption, and update p...
Hi, I'm quite familiar with STM32 trustzone features. Also I know due to there's a random number generator it should be ANSSI capable. But I can't find anywhere a text "ANSSI". Have you as a ST already applied a ANSSI certificate for STM32U545 or any...
