I am working to generate the CRC for the flash memory, During this I am facing hard fault when the CRC module tries to read from certain flash locations, to debug it I made a small loop which assigns the value of each 4 byte. I found that reading at ...
Hello. I'm trying to obtain CRC value from CRC peripheral. It's supposed to give me 8 bit number. Instead it gives me 32 bit number. What am I doing wrong? Below is the code and program outputs. /* USER CODE BEGIN Header */ /** ********************...
I have a strange issue here. I'm trying to do a short, blocking, UART transmission.I have a 23 byte uint8_t array ( MSG ) that I construct before calling the HAL_UART_Transmit() function to send the data. (SLAVE_MSG_SIZE = 23, UART is a pointer to th...
Hello,There is No-Stretch GetCheckSum command in I2C bootloader command, Does someone know what the CRC algorithm used in the bootloader?Many thanks.B.R.Frank
If LL_CRC_INDATA_REVERSE_WORD is set and 8-bit data is provided via LL_CRC_FeedData8(), the resulting CRC is not what is expected. It appears the combination of word-reversal and byte-submission mangles the submitted data in some way, when I had expe...
Greetings. I ran into a problem, I can’t figure out how to become a polynomial if I use not 32 binary mode but in 8 bit mode. MCU STM32F072x8/xBif I use a 32-bit setting, I get the correct data and can process it on a PC, but with 8 bits it doesn’t w...
Hello,I am working with STM32F030RCTx controller. The CubeMx software is not supporting Default Polynomial State: "Disable". I wanted to use a custom CRC polynomial and need help initiating the same. Here is a screenshot for reference:Thanks.
Good morning, I am facing an issue related to the usage of the CRC on the G070RB microcontroller (and user manual RM0454), specifically concerning the use of hardware-based CRC-16 MODBUS for a project currently under development at the company where ...
I'm using X-CUBE-CRYPTOLIB v4.1.0 on an STM32H735. I'm using the libSTM32Cryptographic_CM7.a static library supplied by the crypto library.I'm running into an interesting issue where the address that the binary library is using for the CRC peripheral...
I set up a very simple test project. It is a .ioc file from another project to which I wanted to add a virtual com port interface. I added the vcp in the cube plugin and generated the code. However, if I include a CDC_Receive_FS() function this gets ...
