Hi Jing,
It`s really thanks for your help!
And,can I ask about KL02 function that I tried to connect to KL03 board?
Is there need some settings for KL03Z? I configured the KL03 pin defined and the other. Then I started to Debug,but It came out an error like down below.

Is there something I missed? and can you help me to figure out?
Really appreciate,
Hans
