I am conducting operational verification of the sample application of X-CUBE-SAFEA1 by connecting NUCLEO-L476RG and X-NUCLEO-SAFEA1B.I have some questions regarding the operation of the sample application "STSAFEA1_WRAP_UNWRAP".My questions are as fo...
Hi,We are using an STM32U585 with the application running from external flash, on an octospi bus. We are also using external SRAM. The external memory architecture on our board is heavily influenced by the B-U585I-IOT02A design (same ports, slightly ...
How can I generate the sfu_se_mpu.s file for the STM32H753ZI and STM32H733 controllers in SBSFU?
Hi,I come to you about the key provisioning process for the iROT in the STM32H5.Using TrustedPackageCreator, the keys provided in the file STiROT_Config.xml for the Secure Boot (field <Authentication key>) are both the private and public keys of the ...
I’ve successfully compiled the SBSFU (Secure Boot Secure Firmware Update) code for the STM32H753ZI and updated the firmware. Now, I would like to use it with the STM32H733VGT6 MCU.Previously, I was using the STM32H753ZI controller, which did not util...
Hello,I am having some trouble understanding what bootloader (if any) is installed by ST from the factory for the STM32U5x and what AES key sizes that bootloader supports for secure firmware update. UM2851 only lists AES-CTR-128 (I interpret 128 to b...
STM32H743 - Does RDP protection gives 128 bit flash protection?How to configure for 128 bit.We want to implement read and write protection on the internal flash of the MCU/MPU to avoid unauthorized access through debug ports.
Hello,We are using an STM32H573 with the Secure Manager provided by ST running in the secure environment. In the non-secure environment, we are calling PSA functions. These calls work before ThreadX is launched but fail afterward.According to the pag...
I am using STM32L452RE for an application.I want to implement firmware signing feature on the board so only authenticated firmware is allowed by bootloader to flash on the board. Can i conclude that mbedtls library is popular, but it cannot be used o...
Hi,I am working on the SBSFU default code, which handles swapping content from the download slot to the active slot. However, I need to skip the swapping process and after Decryption download slot boot directly from the download slot.Could you please...
