Q. What is the effect of the eCos license?
A. In the simplest terms, when you distribute anything containing eCos code, you must make the source code to eCos available under the terms of the GPL.
Q. What if I make changes to eCos, or write new code based on eCos code?
A. Then you must make those changes available as well.

A. You do not have to distribute any code under the terms of the GPL other than eCos code or code derived from eCos. For example, if you write a HAL port based on copying an existing eCos HAL in any way, you must make the source code available with the binary. However you would not need to make available any other code, such as the code of a wholly separate application linked with eCos.
Q. I would rather stick with the RHEPL code, but I updated my anonymous CVS checkout.
