User code won't download/run-possible causes?

[nathanww]

Hoping someone can shed some light on this,

Today we were trying to download our program to the cRio, and were unable to get it either to download or to run(we're not 100% sure where the problem lies). Basically, whenever we use the "deploy" option in FIRST downloader, the progress bar just flashes on the screen, and when we reboot the cRio it does nothing and we get a "no code" warning. The odd thing is that using the "undeploy" option doesn't generate an error, so the cRio thinks it has something loaded. Additionally, we can download the example programs and they work fine. START_ROBOT_CLASS is calling our frcv1 class, and the network connection works fine.

Based on the testing we've done, we think that either

1. The build specification is wrong, since our program is showing up as "PPC32diab", but the example shows up as "PPC32gnu"
2. There's some other option that we have to set in order to get the program to run on startup(other than the START_ROBOT_CLASS one)
3. FIRST downloader doesn't like our binary and is failing silently

Does anyone have any ideas on what might be the most likely, or something else that might be going wrong?
