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.

Please check the JTAG HW connection in your custom board and also check this Flash CYW43907 with Segger standard tools (J-Flash, J-Flash Lite, Command Line) to know if you have followed the steps as mentioned here
