I tried to build a simple UART code.
I called HAL_UartInit() function from main.c and HAL_UartInit() is defined in another file hal_uart.c.
I have added function prototype in header file hal_uart.h.
I have added both files in project explorer.
but why it is not getting definition of that function, I think its not linking properly.
please help me, any suggestion would be helpful.
