When shipped, the TI CC1310 LaunchPad evaluation board is configured to be used with the on-board debug probe. In order to use it with J-Link, the on-board debug probe needs to be isolated to make sure that it does not drive the debug signals. This can be done by removing some jumpers next to the XDS110 Out / CC1310 In connector (see image below). After isolating the on-board probe, the CC130F128 device can be debugged using J-Link. Please note, that the J-Link needs to be connected to the board using the CC1310 In connected (see image below).
