I am posting here some of the errors which I get and spend so much of time in solving it as some solutions are not available on web. Again, this is my own opinion, it has no relation with anybody. I will update the post the way I get errors while using it.This way, even I can track the changes I did in my code and people can get the answers.
1. If you try to install apps using telosb on tinyos and if you use tinyos version 2.1.1 or previous, you might get error over msp430. The simple workout solution to the problem is to use version 2.1.2. you can get this version at http://tinyos-main.googlecode.com/svn/tags/release-2.1.2-rc1/
2. Please find this link for problem with sender address in Motelab.
