Good morning everyone,I need to apply the "Closed" product state to my device using the STM32H573VI.I don't need TrustZone enabled and want to use a password for debug authentication.I wanted to perform the operation via "code" using the HALs, but on...
I have exported X509 certificate from STM32H573I-DK board, and checked how it is organised.The certificate was issued by "ST CA 01 for STM32 Initial Attestation".I would like to verify whether it is truely signed by ST's upper-level certificate.Wher...
Hi ST team,I am using STM32U5G9 in my project. It would need simple firmware update feature and the image would be received by UART from a zigbee module.I have read UM2851 and AN5447 application notes and check the SBSFU example in STM32CubeU5 packag...
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...
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...
