HiI tried to generate hex2bin crc32 and then crc32 on stm32 (on words, the rest CubeMX configurations were set to default) , but they are not the same. On hex2bin i can configure big or little endianness, but the result doesn't change and i don't kno...
I cant download the crypto library fromhttps://www.st.com/en/embedded-software/x-cube-cryptolib.html#st_description_sec-nav-tabAnd i think that i saw it among the cube software packs long time ago, but i dont see it anymore.
When compiling UserApp from 2_Images example application for NUCLEO-L476RG linker outputs the following error: cannot use executable file '../../SBSFU/Debug/se_interface_app.o' as input to a linkarm-none-eabi-gcc -z max-page-size=1 -o "UserApp.elf" @...
I've been implementing I2C communication between F401CCU6 and Nucleo F746ZG, while adding CRC I got different outputs, Nucleo provides configurable CRC peripheral, while F401 is by default set to 0x4C11DB7 (https://www.st.com/resource/en/reference_ma...
Hello everyoneI am trying to use the crypto library to perform an AES CCM encryption decryption. I am using an STM32F423CH MCU. The frames I am receiving are comming from other system and the authentication is always failing.I implemted the validatio...
@Jocelyn RICARD I've built, installed and used SBSFU to successfully update the firmware through the serial terminal with a YModem transfer. This update was from version "0" to version "1". Now I have built a new version "2" which only differs from ...
STM32G484QETx is getting locked because of wrong configuration in secure boot and secure firmware update. Kindly suggest me the right configuration along with code and examples. I am attaching a pdf for your reference.
Hi, I am writing this both as a guide to other people struggling with their STM32 AES accelerator, and as a suggestion to STM how to improve their HAL so it is easier to use. My testing and debugging was done on a STM32WB, but i think other accelerat...
Hello,So I'm using a Nucleo-H753ZI (so STM32H753ZI) and I am trying to implement manually (aka without using the HAL library you provide) some drivers of the CRYP module. More precisely, I need to use the CRYP module with AES in counter mode (AES-CTR...
As per current SBSFU Key storage mechanism, we can store One Key per each SLOT wise, as we are going to use single slot, we can configure one Key in SBSFU.Also, if you want to store more keys, we can use other slot keys as well like ECC_KEY2 and ECC_...
