Is it possible to debug a program without JTAG?

Hi Fellas,

I am working on a project and no JTAG debugger is available for me. The current approach I'm using is simply printing variables to DBGU port and frustrating trial/error process.

There are three wires connecting to my device now ( beside supply voltage) that are capable of data transfer : DBGU and USB and Ethernet interfaces which are both and fully functional and I'm quite familiar using them.

Is it possible to use this wires (along with a application in pc ) as a functional debugger? I mean BPs, trace and single step execution ,... and NO JTAG DONGLE AT ALL.

I searched a lot and there a few evedences that it is possible but I cant find any clear instructions.

Thanx.
