I have polynomial for CRC 0x8C. And in STM I must write 0x31, because it is rotate.But I don't know, how to convert this value to good value.In binary:0x8C - 0b100011000x31 - 0b00110001I create function:uint8_t ror8_polynomial(uint8_t poly, uint8_t ...
Posted on May 23, 2014 at 03:03Hi All It is strange but I can't find any code example of how to set up the Ethernet HASH filter for multicast reception. There was a question in 2011 in this forum as to the same but it was not answered - so I will tr...
Our application connects to a server in the cloud and recently we migrated from a proprietary AES256 encryption to Mbed TLS based solution.By default Mbed TLS does NOT offer out-of-the-box hardware acceleration for AES, MD5, SHA etc. By accident I wa...
Greetings, I'm building an app for an STM32L496. I am trying to get the linker to calculate a CRC32 of the ROM image and place it in ROM. I've read a few technical notes on this, and I'm following the ARM example. The problem is I keep getting ...
I am using the STM32F071RB microcontroller and trying to use the en.stm32-cryp-lib to encrypt and decrypt using AES128-CBC. The encryption and decryption functions return expected data when using data that is a multiple of 16 bytes, but don't when th...
Hi everyone, I'm trying to port mbed TLS to L432KC MCU however I lack some knowledge about TLS, is this MCU capable of running mbed TLS? I already have both Ethernet and Internet parts solved thanks to a SPI Wiznet chip and I know that the MCU needs ...
I try this to use this:/* Private function prototypes -----------------------------------------------*/void SystemClock_Config(void);uint32_t CRCtest0 = 0;uint32_t CRCtest1 = 0;//uint32_t CRCtest2 = 0;uint8_t txData[10]={0xF2, 0x10, 0x10, 0xE0, 0x3F,...
Posted on July 16, 2018 at 12:03Does STM32F105RB has CRC function? Why I can't get the stm32f1xx_hal_crc.c in \Drivers\STM32F1xx_HAL_Driver?#stm32f105rbt6-crc
Posted on February 23, 2015 at 12:25I am making a stand-alone SWD programmer for STM32F1 and L1 families, based on STM32F103. For that I have used AN0062 ''Programming Internal Flash Over the Serial Wire Debug Interface'' by Silicon Labs. Everything...
