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...
Hello everyone,My team and I are working with a custom board based on the STM32WB55RG. Due to limited pin availability, we need to use USB as a virtual COM port for serial communication. We successfully configured the USB Virtual COM and were able to...
Hello all,I have been working on a bare metal Rust implementation of the PKA engine in the STM32WBA55CG microcontroller. So far, I managed to properly initialize the PKA engine, and run both modular addition and subtraction by writing and reading the...
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...
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...
Hey guys, how are you?It's been a long time that i'm facing a issue with STM32WB CPU2, most of the times i just fix it without really knowing the cause of it. Basically what happens is after power-up CPU2 simply won't initialize on the first try. I h...
Hello all,I am working on a bare-metal implementation of the PKA engine using the STM32WBA55CG. I have managed to properly initialize both the RNG and the PKA engines, but I cannot seem to load the operands on the RAM. I am trying to implement the mo...
Hello,after being busy with some other stuff, we are finally back to face problems with secure bootloader integration.What we learned so far (our learnt points could be wrong and corrections would be greatly appreciated):ST provides a very nice Cube...
Hello ST,We are developing device and we want to provide free FW updates if some bugs occurre. Updates will be flashed via DFU - usb communication. Currently we are using STM32F411CEU6.Can you recommend best options for protecting the FW from being c...
