Hi,
I have nRF51822 Development Kit: one USB dongle with J-Link OB-SAM3U128 (HW v1.0, dll 4.72) and two boards that can be connected (one of them) to programmer board with J-Link Lite-Cortex-M (HW v8.0, dll v4.72). All the chips on these boards are not recognized and I don't know how to repair that. I suppose that this could be a result of simultaneously debugging two boards in Keil uVision (the problem occurred after this). Also, at the beginning of using usb dongle I found that the Segger chip on it is very hot (55 degrees of C). Is it possible that nRF chip has died?
Some additional data: Keil v4.71, J-Link Adapter Port: SW, Max clock: 2MHz
