How to do: CRYP peripheral on STM32WB
HelloIn STM32 Crypto Library, there are function "AES_CMAC_Encrypt_Init", "AES_CMAC_Encrypt_Append" and "AES_CMAC_Encrypt_Finish" to calculate the authentication code of a plain text.How can this be done on STM32WB using the CRYP peripheral (HAL driv...
Endianness of 'in the air' data bytes
We are evaluating if we can use the STM32 to interface to existing devices. The critical fator is the expected endianness of the data. I have seen no reference in the docs if this can be set, so I have provided an example message and would like to kn...
SBSFU USB Local Loader STM32F4xx
Hi i was wondering how i should go about implementing USB instead of UART to download the firmware in the SBSFU bootloader. I have successfully managed use USB in DFU mode to install a new firmware.
Debugging bootloader + app: How to get a CRC header to the target, too?
I have a workspace in CubeIDE that has two STM32F0 projects: A bootloader and an app.To be able to debug both, bootloader, and then jumping through to the app code, I made an additional Debug Configuration where I added the source folder, and the sym...
Adapting YMODEM to work with USB-CDC Class (on Microcontroller) .
Intergrated USB in SBSFU for FW update, and adapting it to work with YMODEM protocol. Only half of the package is downlaoding to microcontroller. Getting error. I will highly appreciate for any help. = [SBOOT] STATE: HANDLE CRITICAL FAILURE= [EXCPT]...
Problem with self programming after enabling read out protection
HiI've implemented a bootloader that receives, cache and upgrades my main program.When RDP (read out protection) is not enabled everything works as expected with no problem.If I enable RDP. And if I upload the same program as the one already on the c...
Installing Java - I think I may need a commercial licence. Or so ST provide one?
When I run the STM32SecuWS-material.exe installer, it tells me I need to install Java and takes me to Oracle's website. But my understanding is that Oracle Java is not free for commercial use and we would be using STMicro security in a commercial env...
Test F7 SPI CRC Generation
Hello,i have a programm which is sending 2bytes + 16bit CRC from SPI2.There are two STM32F765 on my board. The test programm is generated with CubeIDE and only SPI2 initiallyzed.One MCU is calculating the crc correct and the other is not correct.(Che...
