If I try to open $ mspdebug rf2500 on my Arch Linux desktop to connect to a MSP430G2553 mounted on a G2 Rev 1.5 Launchpad, I have this error, which takes a minute to show up: $ mspdebug rf2500 MSPDebug version 0.22 - debugging tool for MSP430 MCUs Copyright (C) 2009-2013 Daniel Beer <dlbeer@gmail.com> This is free software; see the source for copying conditions.

petus 11 Posted June 4, 2014 Share Posted June 4, 2014 You have to run as root Quote Link to post Share on other sites
SgrA 0 Posted June 4, 2014 Author Share Posted June 4, 2014 I'm sorry, I forgot to specify that it was working a few tries earlier, I flashed some code to it too. Then suddenly this started. Quote Link to post Share on other sites
simpleavr 399 Posted June 4, 2014 Share Posted June 4, 2014 Paste your lsusb, dmesg or any other log output (last few lines) here to identify the problem. Quote Link to post Share on other sites
uberscientist 2 Posted June 11, 2014 Share Posted June 11, 2014 I have the same problem (also on Arch). I ended up just running it with sudo. I read you could just add your user to the "uucp" group and it would work... but not for me Quote Link to post Share on other sites
