Ask questions and find answers on STM32 security frameworks and tools, including cryptographic libraries, TrustZone, and the Secure Manager.
Can recognize the chip, but can not burn and read the flash problem. In this case, is the chip broken or the chip locked? There is also a case that the chip can be identified as burning, but it cannot run the normal working program
In my project, I intend to use an external serial flash to hold UI assets as recommended by TouchGFX.I have followed this: https://community.st.com/t5/stm32-mcus/how-to-implement-and-use-your-own-external-flash-loader-an/ta-p/597752 but I only get fl...
We are planning to use an external flash memory connected via QuadSPI to the OCTOSPI peripheral of a STM32H735 (at a later stage that would be STM32H733).This will be used to run firmware and store downloaded firmware updates with SBSFU. For that we ...
Good Morning,I am working on the Secure Boot using STM32U5 with this repository : https://github.com/STMicroelectronics/STM32CubeU5/tree/main/Projects/B-U585I-IOT02A/Applications/SBSFUI am trying to add a kind of "Dev. Mode" which authorise the boot ...
Hello there,I am practicing with the STM32H573I-DK demo board, STiROT demo project and the chain of certificate feature.I have built a chain of certificates as described in https://wiki.stmicroelectronics.cn/stm32mcu/wiki/Security:How_to_start_with_S...
Hi, I have locked out my MCU. I generated a Debug Authentication file with certificate (DA_Config.obk) and provisioned that into the MCU. However, I think I have regenerated a private key without regenerating a certificate. I am no longer able to do ...
Hello ST Community,I’m working on a project using STiROT with TrustZone on an STM32H533, based on the example STiROT_Appli_TrustZone provided in the STM32Cube_FW_H5_V1.5.0 firmware package for the STM32H573. I adapted this example to the H533 and gen...
Hi, I have managed to extract the OEMiROT project from H533 into H523 and compiled it successfully using STM32CRYPTO library since H523 does only have limited cryptography accelerator. I have modified the flash_layout.h to match my application (which...
Hi allI'm working on a STM32WB55 nucleo boardI'm designing a simple Signing procedureAt beginning I've try that every thing ok by using a hard codded key and now I want to switch on a key kept secure in FUS zoneI've load 2 256 bits AES keys into FUS ...
Hello All,, I am using STSAFE-A110 with stm32f429zit6 for secure boot, I want sample code / library for the same. Also my another query is will I have to sign the firmware using openssl externally. can anyone provide me complete step to finish the s...
