Hi Jing:

I'm using a K60DN512VLL10 and I encountered the same "could not find core in coresight setup" problem.

I'm using Segger V6.56B

I connected with J-Link Commander V6.56b to attempt to unlock my core as suggested by Jing, and the command tool is unable to connect.

It appears to unlock with success but cannot erase.  It encounters the same problem:Could not find core in Coresight setup.

Can you provide other suggestions?

Hi Albert,

If there is no other hardware issue, I guess your chip is locked. Please see this link:
