Hello @trulykk ,
Thanks for your support. The J-Link does support the MCXW71. I did the test with the SDK demo. Please see the figure below.

I've pasted the log below for your comparison.

Script processing completed.
Based on the log, it's a connection issue. I suggest you try the following methods:
1. First, check whether the connections are loose.
2. Perform a mass erase and then try again.
3. Use the J-Link on other development boards to see if the problem still occurs.
Hope it can help you.
BRs,
Celeste
