Re: Failure connecting to Real-Time Target

In my recent experience, when we DEPLOY, it seems to come up OK ... after a small wait.

... but when we BUILD and RUN AS STARTUP, I've found that after a successful download, a 'bot power-cycle is required for it to reliably get that green-light for "valid code" to light-up on the DS.

... and watch your build error messages ... I've Built/Deployed twice in a row without changing anything; the first time, errors, 2nd time no errors at all. That's when I power-cycle the 'bot and wait for that virtual green LED to light-up.

Worked like a charm a half-dozen times tonight.

[edit] ... if you're not even getting the connection light after a power cycle, then you might be experiencing the race-condition bootup of the cRIO and the BridgeAdapter. Fixed with an "arp" command and/or a paper-clip RESET to the cRIO after everything is all powered up. There's an NI forum thread as well as a couple here at CD.
