Hello Tormod, I do not have a JTAG for debugging, but the DSO Nano certainly has a connector for that - CN7 in the picture attached, lower left (sorry for the poor image quality). There are other interesting pads, too: both CN4 and CN5 have RX/TX connectors - one of them should be the console port.
Great idea! I’d love to learn how to debug at device level: at present I’m pretty much lost without an OS underneath.
