RTT viewer problem

[air]

 Hello,

I am developing using nrf51822 and J-Link.

In the Keil4 version, the RTT viewer worked fine, and only the project was migrated to the keil5 version,

but the RTT viewer doesn't work.

The code and configuration was not changed.

What is the problem?

What should I do?

 thanks.

Hello,

are you able to flash the application? Are you using DK or custom board?

I knew that was reset order between BD/J-Link.

It's not DK BD.

1st power(USB) is for J-link and 2nd power(power supply) is my BD.

In this order RTT viewer works well.

Thaks for your interests.
