Hello ST Community,I'm currently working on a project using the STM32WB55 MCU and am in the process of implementing Secure Boot and Secure Firmware Update (SBSFU) in my custom application. As part of this, I decided to test the existing 1_Image_SBSFU...
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...
The call to "cmox_rsa_pkcs1v15_encrypt" requires a "Random buffer" and a "Random Length (in Bytes)" as input parameters. It will return error code CMOX_RSA_ERR_WRONG_RANDOM if "Random material too short or not valid for the functionality".I keep gett...
Hi,I am replacing Standalone Loader(Ymodem serial) and porting BLE_OTA in SBSFU as mention in AN5056 section 8.4 How to replace the standalone loader with a BLE OTA loader i am successfully ported and run BLE OTA but as wireless stack not started it ...
I need to know how to build binaries (RSS, User Flash App with OTA, Wireless stack) for STM32WB series.Can you share any document regarding building these binaries?
I have followed a tutorial (https://www.youtube.com/watch?v=i10X4Blr8ns&ab_channel=STMicroelectronics) to try and get a simple BLE application running and view this application using ST's BLE Toolbox on my Android phone. However, I do not see my devi...
AN5185 specifies that encrypted keys should use AES-128 GCM, but the format of data sent to FUS isn't very well specified:Byte0: key type:• 0x00: None• 0x01: Simple key• 0x02: Master key• 0x03: Encrypted keyByte1: key size N in bytesByte2 to ByteN-1:...
Hi,I am currently trying to change RDP level via firmware without a power reset (POR) on a NUCLEO-WB55RG (STM32WB55). I am facing the problem that after changing the RDP level a power reset is necessary. Without a power reset the device seems to get ...
I am building a custom loader for SBSFU on the STM32WB5MMG. The loader is similar to the BLE_Ota loader, but instead of using BLE, it loads firmware/wireless stack from an onboard microSD card, as well as being able to write CKS keys.I do need to hav...
