Get "Trace Hw no present" on segger j-link

pikachu

Hi guys

I am using customized board(Raytac MDBT40) based on nrf51822(flash memory 256k, RAM 32k).

I am trying BLE UART example code of SDK 11.

which path : \nRF5_SDK_11.0.0_89a8197\examples\ble_peripheral\ble_app_uart\pca10028\s130\arm5_no_packs

Now I want to use debugger to run it, so I install segger j-link.

I connect nrf51822 and j-link by SWODIO, SWOCLK, GND,

and set configuration in keil ARM(μVision V5.23.0.0) as illustrated.

Before loading code, I upload softdevice s130 v2.0 by nRFgo.

It seems fine until press "DOWNLOAD".

But I get "trace hw no present" after press "Start Debug".

What is the error message mean?
