Ask questions and find answers on STM32 security frameworks and tools, including cryptographic libraries, TrustZone, and the Secure Manager.
Also, the crypto functions require a key made up of an exponent and a modulus. The examples only show these as two separate arrays. How do I get from a single array I have hopefully included from the pem file into these two separate arrays? What is t...
Hi, I have nucleo-h753ZI and I want to use CRYP in a project that also uses FREERTOS. I set Timer 6 as Timebase Source (recommended due to FREERTOS) and as a result, program goes to HardFault every time I use HAL_CRYP_Encrypt function.HAL_CRYP_Decryp...
Does the controller perform a CRC confirmation check before running the application to check if the firmware is corrupted? If so, where does this happen; in the bootloader or the application itself? What does it do if the CRC turns out to be wrong? S...
Hi,I am currently working on a bluetooth application, on an STM32WB55 microcontroller, to which I have integrated OTA update functionality.As Loader I used the one present in the provided code examples.The application and downloads work properly, my ...
How do I calculate the SPI CRC-16 in C? I have an STM32F429 sending me SPI data. These are the SPI settings:How do I implement a CRC-16 check implemented in C (not using STM32)?It is 16-bit data with LSB first. Polynomial X1+X3
How can I manually calculate the SPI CRC in C? I can't seem to find any information about this.
Do we have any mechanism to know about Software validation check status ??in case of reset, SBSFU will check for validity of application, before jumps to it. And in case of fail, it won't launch application, The failure status, how can we know ??Do w...
Hello Gentelman,In my algorithm, I need to calculate 2 types of CRC with different polynomials. Is there any way to avoid keep deInit and Init CRC, and change the value of polynomial dynamically?
Hey guys,I need to replace Uart for USB on my SBSFU local loader. I manage to create the USB comm in SBSFU quite easily, using UART structure provided in the SBSFU examples. My problem is when i receive firmware header, my code get stuck on the follo...
Greetings. I am developing a LoRaWAN application running on the STM32WL5, the application does work and makes use of the flash memory to store the application eui/network key (so that it is not necessary to recompile the firmware each time), the keys...
