Weird problem..
 

For some reason, printf()'s only display while the robot is still on after being programmed. If I reset the robot, the printf's come across garbled..

Any way to fix this? I'm not even sure what could cause it (I did remove user_serialdrv from the project, and all code.. when I re-add it I get the RC program light flashing between red and green)

I'm not sure what you mean by garbled, could you show me the line with the printf and maybe better explain what garbled means?

Example line
printf("Pos is %i\r",(int)cpos);

After I program, it comes across as Pos is 204
After reset/power off it comes across as maybe |8|8|8|8|8|8|8|8|8|8 or some other random stuff
