You can get support for Buildroot through three main channels:
The Buildroot IRC channel is #buildroot, hosted on Freenode. If you do not have an IRC client, you can use the Freenode web interface. When asking for help on IRC, share relevant logs or pieces of code using a code sharing website.
Please search the mailing list archives before asking questions on the mailing list, since there is a good chance someone else has asked the same question before. Checking the archives is a great way to avoid annoying everyone on the list with frequently asked questions...
If you encounter any problem while using Buildroot, you can use the Bug Tracker to post your bugs and/or participate to find solutions to existing problems.
Note: patches are only accepted through the mailing list.
