It depends on how you define compatible.
YAFFS2 CVS is as far as i understand GPL. eCos is GPL with an
exception. You can combine the two, but you effectively loose the eCos
exception. The eCos exception stops the GPL on eCos spreading into
your application. The YAFFS2 GPL code will spread its GPL license into
your whole system, ie eCos and the application code. Your application
becomes GPL.
For many commercial application of eCos this is not wanted. YAFFS has
a solution to this problem. You can pay some money and get a copy of
YAFFS which is not GPL, it has some other commercial license. See the
YAFFS website.
