Error during compile of Megablink demo using freeRTOS for atmega2560 using WinAVR

Question

The following RTOS .c files compile fine during 'make':

task.c, queue.c, tasks.c, croutines.c, list.c

Then I get the following error:

serial.c: In function 'xSerialPortReInit'

serial.c: 665:error: 'ulWantedBaud' undeclared (first use in this function)

serial.c: 665:error: (Each undeclared identifier is reported only once for each function it appears in)

make: ***[serial.o]Error 1

---

I have checked that all include files identified in serial.c are available

Answer 1

Why do you think it is an include file problem? ulWantedBaud is more likely to be a function parameter, or file scope variable, that is misspelled. The AVR demo in the official FreeRTOS download (whic is very old and probably not the best reference) contains a serial port init function with such a parameter, although not a re-init function as per your post:

xComPortHandle xSerialPortInitMinimal( uint32_t ulWantedBaud, uint8_t uxQueueLength );
