Troubleshooting¶

This document is to be used as a guide when programming to ensure all critical points for error are considered.

Below is a quick checklist for points to consider when programming.

[ ] Lib-common, if included, is compiled.
[ ] Added files compile.
[ ] ‘PORT’ in makefile is set to the correct port. See below for details.
[ ] All necessary lib-common modules are initialized.
[ ] Build folder is included.
[ ] CoolTerm / Xterm baud rate is set to 9600. Appropriate port is set. See below for details.
[ ] 6-pin programming header is connected to the PCB.
[ ] If using CAN, the CANH and CANL pins are connected between PCBs.
[ ] In your program, all the necessary components/libraries are initialized.

If the quick checklist has not cornered your error, let us first troubleshoot the software.

Hardware¶

[ ] Check that you have clicked on the Connect button
[ ] Click on the Options button and ensure your port is correct. This port should not be the same as the port in your makefile.
[ ] Check the baud rate (use 9800)
[ ] Ensure the UART wire is connected to MOSI pin on the board and to the RX pin on the Pololu programmer

Read compiler warnings!!

[ ] Check your port on the makefile. (For macOS use ls /dev/tty. *), for Windows use device manager)
[ ] Change programmer micro-usb
[ ] Change programmer
[ ] Change PCB

[ ] Add a print statement after init_uart() to see if your program executes on the board
[ ] Use various print statements throughout the program to see how your program executes (print useful variables)
