Re: [MiNT] Kernel debug messages serial port

[David Gálvez <dgalvez75@gmail.com>]

The question quoted below was asked by me some months ago, now i've
wrote an article in the wiki that explains how to do serial port
debugging with Falcon.

http://wiki.sparemint.org/index.php/Debugging_through_Falcon%27s_serial_port

Corrections and suggestion welcome, when finish It could go in the
programming section.

PS: It was the first time i've used a wiki, how can i create a new
article?, what i did is to edit my user page and then move it later
with a new name, i guess this it's not the right way.
