To debug kernel modules with JTAG, you have to have a debugger which is kernel aware like Lauterbach. If you don’t want to use JTAG, then use printk or dev-dbg, dev-err, etc. You can also use ftrace, which requires you to build your own kernel and add support for the various ftrace features. Read kernel docs under documentation/trace/ftrace.txt to learn more.
