 ====== Using the MSP430 Launchpad in Arch Linux ====== ====== Using the MSP430 Launchpad in Arch Linux ======
-Start by installing all the stuff listed in the top part of [[http://losinggeneration.homelinux.org/2010/07/02/msp430-launchpad-on-linux/|this document]].+This guide is, for the most part, based off of [[http://losinggeneration.homelinux.org/2010/07/02/msp430-launchpad-on-linux/|this document]]. I'm duplicating much of it here because 1) if it goes down we'll have lost a valuable resource, 2) some of what he says is outdated/wrong, 3) he's wordier than I am, 4) my methods are a bit easier, I think.

-Now at this point, things get a little bit convoluted. I think the guide linked above does a few extra/weird things, but whatever, it works.+Now you're at the (mspdebug) promptand you can do things like program code to your msp, erase your msp, look at the data on the msp, etc. I don't know what all can do, but I get the feeling that it's fairly powerful if you know what you're doing. 
 +To program your code onto the chip, first type 'erase' at the prompt to make sure the chip is wiped. This will take about a second. Now type 'prog main.elf' and whamo-blamo, you've programmed your MSP430 in linux.
-At the (mspdebug) prompt, type 'erase' to wipe the chip, then type prog main.elf and your program will be dumped on the chip. Now you need to start the debugger. I suggest you use tmux or screen for all of thisbecause you'll need two terminals at onceIn the first terminal, run the command 'gdb' and switch to another terminal. Here, run msp430-gdb main.elf as standard user. At the (gdb) promptenter 'target remote localhost:2000' and then type continue. After a few seconds, your program should start and your LED will begin blinking.+If you want to do realtime debugging and stuff you can mess around with msp430-gdb. I've not found much use for it yetbut I'm sure that one day there will beIt'little bit complicatedso if you're interested in it you can read about it in the guide linked at the top of this page.
