I made a few modifications in the sbl2ex FactoryApp and loaded it int my sbl2ex--and nothing happened. No boot messages, no functionality, no +++ response, no response to 'A' during first two seconds...nothing. The uart tx line drops to about -6v, so I know the power is supplied.

For a little while, NBConfig (within the NBEclipse IDE) still found it, and I set it to "Boot to Monitor", then cycled the power. Still nothing. Now NBConfig can't find it either. (nor AutoUpdate, nor IPConfig, nor VirtualSerialPorts.) It's like it isn't there.

Is there a jumper setting on the sbl2ex to force it into the monitor? Or any other way to even check for a heartbeat?

Boot to monitor is boot to the serial monitor....
So no network tool will find it.

You need to do a serial recovery and use the monitor to set the config back to boot to application.
