Debugger Update

A project log for ARM Dev Kit Project

ARM seems interesting. Documenting notes while I learn it.

For all previous logs and tests I was using the built in USB programmer that came with the dev kit. I have no plans on incorporating these components into my theoretical application, so I acquired an LPC J-link2, a debugging tool external to the dev kit. The LPC J-Link 2 has a 10 pin SWD (Single Wire Debugger) with a 50 mil header. This header makes the LPC J-Link 2 more usable than the built in USB programmer in general case, but not especially friendly because it does not fit onto a standard bread board. I might need to make an adapter board for prototyping purposes.

I will be working exclusively with the LPC J-Link 2 from the remainder of this project.

Aside: the LPC804 has internal pull ups on the clock and data lines from the SWD turned on by default. This eliminates 2 parts from the any potential BOM.
