Ask questions and find answers on STM32 security frameworks and tools, including cryptographic libraries, TrustZone, and the Secure Manager.
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. ...
For storing my crypto key I'm using the following function to store the key in the WB55 core 2 secure key storage:uint8_t key_index = 1; SHCI_CmdStatus_t result; SHCI_C2_FUS_StoreUsrKey_Cmd_Param_t CKS_param; CKS_param.KeyType = KEYTYPE_S...
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...
Hello,I'm struggling to find any information regarding possibility to remove the keys stored through FUS CKS.My understanding is, if the keys are constantly being stored to some reserved space in flash memory, this reserved space will eventually be f...
I have a strange issue here. I'm trying to do a short, blocking, UART transmission.I have a 23 byte uint8_t array ( MSG ) that I construct before calling the HAL_UART_Transmit() function to send the data. (SLAVE_MSG_SIZE = 23, UART is a pointer to th...

Hi ChannelI have tested the TF-M Package Released by ST, on the STM32U585 and its working fine. Now i want to revert back my STM32U585 (B-U585I-IOT02A Kit) as for the testing of TF-M SBSFU there is some configuration of option bytes as given in UM285...
Hi all,I am using STM32F769I-DISCO Board IDE : 1.12.1CubeMx : 6.10.0 ST CUBE programer version 2.15.0I am not able to flash, I am getting following error during flash,I tried changing SWD freq and Connect mode: Under_reset Log output file: C:\Users\M...
Hello,I try to build the STM32CubeExpansion_SBSFU_V2.6.2 for STM32H750B-DK. I use STM32CubeIDE Version: 1.9.0 on Windows 10.The build result is suspicious: More details: The first section is overflown by 3479%. What I did wrong? How to fix it? Th...
Am testing the x-cube-sbsfu on H7A3 (using H7B3 project with OTFDEC disabled). After enabling SFU_MPU_PROTECT_ENABLE, I always ran into mem manage fault when the function HAL_RCC_GetPCLK1Freq is called during HAL_UART_Init: An MPU or Execute Never (...
