Is it possible to get some guidance (or pointer to a document) which details how to setup the CYW920719Q40EVB-01 evaluation board for debugging via an external JLink using SWD.
We are using WICED v6.1 and have successfully compiled and downloaded the demo.hello_sensor-CYW920719Q40EVB_01 target (using demo.hello_sensor-CYW920719Q40EVB_01 DEBUG=1 download).
Additionally, we have also reviewed the CYW207x9-JTAG-Debugging.pdf file in the ../sdk/Doc folder (which is referenced in the CYW920719Q40EVB-01 Evaluation Board User Guide) but it seems that the instructions pertain to the CYW920719WCDEVAL board which has a JTAG connector on its J2 socket (as opposed to the CYW920719Q40EVB_01 which has an SWD on its J13 socket).
Needless to say, despite pressing ahead and following the instructions in the CYW207x9-JTAG-Debugging.pdf guide, we have thus far failed to establish any connection to our target board. The following output is from a command line session of the JLinkGDBServerCL process...

In short, we would be extremely grateful for debugging guidance that specifically pertains to the CYW920719Q40EVB-01 evaluation board at the very least.
Thanks in advance and Regards,
