I've implemented on my own board (MCU STM32WLE5CCU6) bootloader SBSFU from example 'STM32Cube_FW_WL_V1.3.0\NUCLEO-WL55JC\BFU_1_Slot'. Everything works ok.In my own aplication i must change download channel from usart to by radio FSK. Because of handl...
Hello,I am working on a large project on a custom board based on STM32 L5 series. I've already set up, implemented, and tested my code using STM32CubeIDE. Now, I'm trying to integrate the project into SBSFU. For that reason, I am using the SBSFU exam...
Hi, I'm trying to build TFM example applications from the B-U585I-IOT02A directory to work on Nucleo-U545RE board. THe documentation says it's possible. I have updated the project settings, but I'm getting errors from the STSAFE library: C:/Work/OldC...
Hello,We are developing a product based on a STM32WB5MMG. We have configured the SBSFU with OTA (Asymmetric with AES encryption scheme). Everything is working great and I have only one question that came to my mind during the last commit...The CBC ke...
Hi,I'm trying to get access to the UID registers (address 0x0BFA0700UL) of the CPU with the above configuration from the non secure application. The secure fault callback is getting called. I have tried adding an entry in the boot code file low_level...
Hello @stI am taking the reference implementation of the HKDF Algorithm using PSA API in the TFM Application Project and using the following algorithm :PSA_ALG_HKDF(PSA_ALG_SHA_256);I m able to export the output key to the console and am getting an o...
Hello, I am using STM32U585 TFM architecture for one of my project. Which basically is a combined project of 5 internal projects as usual TFM(mentioned below).1. TFM_Appli_NonSecure2. TFM_Appli_Secure3. TFM_Loader_NonSecure4. TFM_Loader_Secure5. TFM_...
Hello,I am working with STM32CubeU5 TFM v1.5 for STM32 u585. I develop a custom loader using CAN communication. First I used MCUBOOT_OVERWRITE_ONLY and MCUBOOT_PRIMARY_ONLY setup. The CAN communication worked fine (in non-secure loader).Then I switch...
I'm interested in understanding the modifications required to adapt the 'STM32Trust security framework' code, accessible on the STM website for STM32L5, for my project of developing a secure bootloader code specifically designed for the STM32G070RB. ...
From AN5185 I understand that up to 100 keys can be send to FUS for storage, but any index will only be written once. So once I have reached 100 writes, e.g. because I have constant pairing keys between devices but I allow to disengage and reengage s...
