System Workbench for STM32


STM32F767ZI nucleo board printf to console

Hello. I have read through the website that you have suggested, unfortunately still cannot fully understand how printing to console works and differs from printing to any other serial console.

I am able to print to serial console ( see image4 in the attachments).

I have tried replacing the _write with whatever has been suggested in that website:
```
int _write(int file, char *data, int len)
{
if ((file != STDOUT_FILENO) && (file != STDERR_FILENO))
{
errno = EBADF;
return -1;
}

// arbitrary timeout 1000
HAL_StatusTypeDef status =
HAL_UART_Transmit(&huart3, (uint8_t*)data, len, 1000);

// return # of bytes written - as best we can tell
return (status == HAL_OK ? len : 0);
}
```
However, still no text appearing in cubeIDE console window. How can it work in serial terminal but not the cubeIDE console?
