This bridge is what I was referring to. Newlib calls read() but does not provide an implementation of it. Libgloss provides various target-specific implementations of read(), the one I wrote for msp430 uses CIO to communicate with the simulator/debugger. > I was expecting for MSP430 to also simply implement the functions > stubbed in newlib's libnosys, but at first glance it looks like the > CIO one uses different names, and maybe doesn't support all the same > functions. Hmmm... it should be all the same names. I only changed the existing libgloss hooks. But, I don't always do all the hooks, usually only write() and exit() are needed for our testing. ------------------------------------------------------------------------------ Start Your Social Network Today - Download eXo Platform Build your Enterprise Intranet with eXo Platform Software Java Based Open Source Intranet - Social, Extensible, Cloud Ready Get Started Now And Turn Your Intranet Into A Collaboration Platform http://p.sf.net/sfu/ExoPlatform
