Cannot debug the multillink_central example (s120)

[Kyu]

Hi nordics.

I am trying to do s120 multilink_central example.

However, this example doesn't work well, and I cannot debug central example.

-Environment-

board: nrf51822 DK (6310)

debugger: J-link lite.

sdk version : 6_1

softDevice version: s120_nrf51_2.0.0

--

First, I set the ROM1 start:0x1d000 , size 0x23000
and RAM1 start 0x20002000, size 0x2000 for s120.

and, I set the J-link driver like this....

And I found that I can program this example with nRFgo studio, but i can not download with "download button" in the uvision tool.

When I try to debug this, I get this error message.

How can I solve this problem?
