Thanks for the reply I did the ./disable_cdc.sh

without the ./disable_cdc.sh

it will not reach "J-Link is connected." stage,

JLink has an issue with CDC on the OSX. You can get a shell script here http://hg.cmason.com/nrf to disable CDC driver on OSX in order for JLink to work properly.

The best Eclipse plugins for OSX is here gnuarmeclipse.livius.net/.../

I suspect that what you see is an issue with OS X and the Segger OB's CDC implementation, in that OS X's CDC driver requires exclusive access that messes with the GDB server's connection to the chip. If so, you should be able to get things working by unloading the CDC driver. Take a look at this question over at Segger's forum for details.
