Trouble connecting to cRIO?

[darty]

Hey RMiller, your suggestion seemed like the most likely problem, so I walked into a meeting today with that as my prime suggestion, turns out another team member looked into it and reached the same conclusion. As soon as we get our laptop we'll check..

You may have to put a jumper on the digital sidecar, so it passes 5v through the PWM cable.

edit: oh, so you seem to have confirmed it's a code problem then... nevermind.

BAD!!!

Make sure that you reset the cRio after downloadiing the code. If you've re-flashed, you MUST do a complete power down to init the FPGA. I would recommend connecting a terminal program via the RS-232 port on the cRio so that you can see exactly the error that is causing the nocode condition. That's how we fixed ours. Its pretty hard to understand what is wrong with the code without knowing why. Error messages will be displayed via RS-232 with codes that correspond to vxworks errors and warnings. HTH
