The last time I updated it was the end of October, so don't be suprised if the eCos source code has changed quite a bit--installation might not be as straightforward as before. I'm actually planning on updating to the current CVS version next week. Look out for a bug somewhere in the mutex handling code: I'm sure it's related to the interrupt handler code. Stay tuned for that fix. But in the meantime, that package allows you to construct a GDB stub on a floppy disk, so you just boot from that and then connect to the debugger from COM1. If you have any significant problems, just e-mail questions to this list, that way everyone benefits from the discussion.
