The previously mentioned mailing lists are open to all to use freely and core eCos developers read and post there. However the scope is limited as to what can be answered, and queries or problems, even simple ones, may be ignored.

Bug reports can be submitted to the bug tracking system which allows the issue to be tracked in a more reliable manner, however prompt replies are still not guaranteed.

Some businesses provide commercial support more suitable for businesses. Contact the eCos maintainers with your requirements and they may be able to put you in touch with an appropriate vendor.
