Ask questions and find answers on STM32 security frameworks and tools, including cryptographic libraries, TrustZone, and the Secure Manager.
I am currently working with the STSAFE-A110 and I have noticed a significant lack of documentation for those who need to implement or understand the driver logic.For instance, when generating ECC asymmetric key pairs, the official datasheet mentions ...
I'm working on a project which is being ported over to be TrustZone aware, part of this project makes use of an OCTOSPI configured in memory mapped mode for file access. Base settings come from the IOC however the memory mapping is executed in source...
Hello,After creating a new project based on the FreeRTOS_Queues_ThreadFlags_TrustZone example from MX and generating code, there is a compile error:[build] C:/Users/tuoma/AppData/Local/stm32cube/bundles/gnu-tools-for-stm32/13.3.1+st.9/bin/../lib/gcc/...
I have a working program on my own board using a STM32G081KBU6. Debug using SWD and programming a release version works fine. As long as RDP remains at Level 0, I'm able to debug, erase and reprogram updates to the board.Usually for other ST MCU's th...
Hello, I'm posting a new message because the previous one was not answered with successful connection. The problem is that when MCU is populated on my board with Read-Our Protection enabled, it is not possible to connect STM32CubeProgrammer v.2.21.0 ...
Hello,I'm looking for some clarification over how the PCROP area can be used. The user manual for STM32L471 states that code in this area can be executed but that data at flash in this area cannot be read. Does this mean if I put a decryption algo...
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...
