Downloading code DS says "No Code"

KRibordy · #1 24-01-2009, 13:33

When we download the code, we download it with WindRiver and then reset the robot. Then, on the DS, it should display "Battery: No Comms" for about ten seconds. Then, for another few seconds, it will display "Battery: No Code". Then it displays "Battery: 0.0V" for us. When that message is up, the joysticks start working.

For us it just stays on "No code" and never displays a Battery voltage and the joysticks dont work.

You are resetting the robot after downloading the code, right?

And you're downloading the .out file to the robot, not the .cpp file, right?

Yes we're resetting the robot and downloading the correct file

We've had this problem a few times with our bot. It's usefull to have a serial connection to a terminal on the programming computer. During boot-up, if it says it "unloads" your code, there is probably part of the code the cRio didnt like. Generally, for my team, it was because of an "inline" function.

Is there a document that tells how to use the serial interface, and what information the interface yields?

Directions are found in the Control System Manual Chapter 5 Configuration in section 5.4.1, cRIO Console Serial Connection to Laptop

Thanks. There is also a more detailed account at NI for those following this thread:
