An important note here is that some low-level debug output can't be gotten from the remote console or the dashboard--you have to have a serial connection. This is because the cRIO doesn't autmatically output anything over the network connection, so if problems exist that prevent a program from loading at boot you'll need a serial cable to see what's wrong

I believe that you can use an old IFI tehter cable plus a null modem to do this.
