Ask questions and find answers on STM32 security frameworks and tools, including cryptographic libraries, TrustZone, and the Secure Manager.
I hope this message finds you well. I am encountering an issue where I cannot access the RAM and Flash usage statistics within the Build Analyzer feature of CubeIDE version 1.15.1. Upon attempting to view these metrics, the fields appear empty, preve...
Hi,I am doing feasibility on SBSFU bootloader on STM32H753ZI. Currently in our firmware we are planning to have a custom bootloader based on SBSFU for secure boot and update. But I came across SFI feature from ST to ensure protection at the manufactu...
Hi,I have followed below youtube link for enabling debugging for TFM firmware successfully.https://www.youtube.com/watch?v=rlmQhfXyYCQ&list=PLnMKNibPkDnGd7J7fV7tr-4xIBwkNfD-- I enable single binary for both Appli_NonSecure and Appli_Secure by choosin...
I can't get ECDH working for CURVE25519 using the STM32 HAL / crypto lib. This may be an issue with the somewhat confusing constants for this library. I can get the NIST curves working with ECDH. The trouble I have is it seems there are two cmox_ecc_...
Hello Team,As we approach the final stages of our project, we're exploring options for deploying the Secure Manager and Application efficiently. We're particularly interested in whether it's feasible to install these components via UART or alternativ...
Hi @Jocelyn RICARD Greetingswe are working on the STM32u585 TFM Application and are facing issues when running the code. the issue is after dumping the code using the TFM_Update.sh script first time every operation is normal, but while running for th...
Hello,I have a use-case with a soldered battery, which I can not power-cycle after programming, however I have to set option bytes to restrict Flash reading.I found online that going into STANDBY mode or rather, returning from STANDBY mode, would upd...
Hello everyone,I am working with the STM32H7B3 and after enabling the secure user memory, i am not able to connect with the debugger anymore:For testing if secure user memory works, i put a "secure_function" in a section at the end of my flash, then ...
Hi, I just accidentally modified the PRODUCT_STATE to provisioning and not able to recover.So, I tried to do the OBKey Provisioning and use DA to regression back to Open State.I've created my OBKey:However, provisioning always failed.Is there any oth...
I am worried about the data that i send through the STM32WL55JC if any outsider with the same board and using the same frequency in receiver mode ,can also get the data that i am sending through the transmitter using same frequency ,How do i secure m...
