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 ...
My controller is STM32L462. I need to compute CRC16 for Modbus application. There is CRC initialization function:void MX_CRC_Init_CRC16(void) { hcrc.Instance = CRC; hcrc.Init.DefaultPolynomialUse = DEFAULT_POLYNOMIAL_DISABLE; hcrc.Init.DefaultI...
I have an STM32L073CZ that I'm having an occasional error with. I'm using the HAL libraries to program EEPROM and a number of our MCUs are seeing errors where they fail to write the first word. After that it'll start working correctly and everything ...
Hello, I know this has been discussed before, but following your procedure i am still unable to generate with srec_cat the same CRC of one generated by STM32 CRC hw peripheral.did you make some other tricks in order to have match between the two CRC...
Hi community, I am working on CRC generation with polynomial 0x8005 and initial value 0x0000, so I configured it as belowI am using the data as shown below and the CRC should be 0x43B8 but the value got from the API is different. So I am missing some...
Hey, I went through the manual of the STM Programmer command line interface and implemented a post build CRC calc with the Safety lib command -sl.C:\PROGRA~1\STMicroelectronics\STM32Cube\STM32CubeProgrammer\bin\STM32_Programmer_CLI.exe -sl MESOL_CAN_...
In previous development project we were able to place several variables with a magic number and checksum of the application at the end of the interrupt vector table that the bootloader could use to check if a valid application existed.Since the STM32...
I'm running SPI with DMA and CRC enable between two stm32, slave is stm32f415 MCU.Sometimes it appears that data received is corrupted whereas CRC check gives no error. For instance (polynomial used is 0x1021)Normal behavior:3 words sent: 0xAAA0; 0x0...
Hello, I'm a bit stuck and I am not sure what to do so I am asking for your help.Here is the problem :I have a custom board with a STM32WB35 that was working fine for a while. But after multiple (incomplete) boot when I was soldering the battery to m...
I am using the STM32F746VET6 which was setup with STM32CubeMX project. In the code it creates I see there's a STM32F746VETX_RAM.ld linker file and a #define VECT_TAB_SRAM to locate the IVT in RAM, but I don't see in MX where I specify that I want the...
