Ask questions and find answers on STM32 security frameworks and tools, including cryptographic libraries, TrustZone, and the Secure Manager.
We need to develop an offline programmer to program the STM32H562VIT. The product state need to be changed to Closed with an OBK file programmed. The OBK data only in HDPL1.We can't simply use the RSS to program the OBK like STM32Cubeprogrammer. We c...
STM32 H573 TrustZone Enabled question. I'm executing the STM32 H573 example for TrustZone Enabled (OEMiROT, Secure, and Non Secure Apps). I know the OEMiROT and Non Secure App prints out and logs info, but I want to be able to do that in the Secure ...
Hello, I am looking for guidance regarding the STM32H533 MCU, specifically in the area of secure and non-secure memory management.Could you please let me know if there is a dedicated application note that explains how to store and manage encrypted ke...
Hi,I am using STM32H563 with OEMiROT_Boot example project, I got a problem to read the FLASH_SIZE register (0x08FFF80C).I found two issues,(1) the value of this register is 0 at begining of OEMiROT_Boot main() function.(2) the register become not acc...
Our own non-secure application is based on "SMAK_Appli" in the STM32TRUSTEE-SM example and in principle, it works, but debugging is giving me issues. This is with STM32CubeIDE latest version and all tools software and firmware updated to their latest...
Hi,I am using STM32H56x with OEMiROT_Boot example project, and I use MCUBOOT_SWAP_USING_SCRATCH to install application images, is there an API like boot_set_confirmed( ) can used by secure applicaiton code, or a confirmation flag in SRAM like STM32H7...
Hi, I am working with the SBSFU_Boot on the STM32U5A9 chip. After the SBSFU_Loader has written the update image into internal memory, a reset happens in order for the SBSFU_Boot to write the image to be booted. When performing the update, it ends up ...
Hello, I have an STM32H755 nucleo board and I want to use the secure memory area features but I need to clarify my understanding of the reference manual "rm0399" and some follow up questions.My understanding is that:From my normal code (non-secure) i...
All the provided examples are using USART YMODEM to transfer data. I know, that it really doesn't matter what kind of protocol you use as long as image is placed in a correct place in the memory, but I wonder if I can use DFU feature to update firmwa...
Hi Team,Firmware file are just signed not encrypted through STM32 SigningTool - stm32mcu (STM32_SigningTool_CLI.exe) after generating public and private keys through STM32_KeyGen_CLI.exe.Public key in raw 64 bytes is provided to bootloader_main.c as ...
