Are you sure that this isn't just multilib generation? There are a lot of multilibs to build as I recall. But in any case, there were some problems with the thumb support in the eCosSWtools compiler we put out. We have fixed these now, but since thumb-elf isn't a supported eCos toolchain target, we won't be doing an update. In fact, the best thing to do is use egcs. Most eCos targets should now work with egcs (although I know sparclite doesn't). If anyone is feeling energetic, they could give that a try. egcs is at http://egcs.cygnus.com/ You may also want to use the latest binutils from http://sourceware.cygnus.com/binutils and gdb from http://sourceware.cygnus.com/gdb If you do go down that route, let the list know how you get on, and just ask if you have any problems. I'm sure someone should be able to help. Jifl -- Cygnus Solutions, 35 Cambridge Place, Cambridge, UK.
