Noticed the OPENSDA circuit has the dedicated SWD/JTAG interface on board for the K20DX128. I'm thinking I may use this board for both KL25 and K20 development.


I tried to connect with JTAG then directly debug the openSDA code.


But I failed in JTAG connection with the K20 onboard. The JTAG can't find the K20 core. I double checked the connection. Shall be OK as I used K20 before in other projects.


Did you guys ever try this on Freedom board?
