You can't build eCos in thumb mode. There is a bug in gcc at the moment which makes the build operation fail. (Still there with CVS sources of Monday). You can build eCos in ARM mode with thumb interworking enabled, as long as you also built newlib with interworking enabled. You can then build your app in thumb mode (with interworking). There isn't a fully satisfactory solution yet. === Lewin A.R.W.
