Hi. We have custom board with CYW43907 chip. When connecting with J-Link raised next problem. "Could not power up debug port. Control/Status register reads 00000103. Failed to connect". Our design similar to CYW943907 Evaluation Kit.

Any suggestions to resolve this problem? What we do wrong?

Thanks.
