Hello ST Community,I'm currently working on a project using an STM32 microcontroller and encountering a critical issue related to mbedTLS during SSL handshake processes. I’m seeking insights or solutions based on your experience with similar hardware...
Hello everyone, I hope you are well.I'm working on a project and one of the requirements is connection to AWS, so I chose to start with the STM32H573I-DK kit, where following the "STM32CubeExpansion_Cloud_AWS_H5_V1.0.0" step by step I managed to conn...
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...
Dear community,I have been experimenting with secure boot on the STM32H573I-DK using the latest git checkout of STM32CubeH5 (see https://github.com/STMicroelectronics/STM32CubeH5).The STiROT and OEMiROT examples run fine out-of-the-box. However, when...
I get a 404 Not found for this ST URLhttps://wiki.st.com/stm32mcu/wiki/Security:Introduction_to_Manufacturing_for_STM32H5I'm specifically looking for the manufacturing flow with chip-specific licenses
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...
