- Howdy - I am involved in developing a device driver to support some custom
- nubus hardware and am having a rather difficult time debugging my code.
- Before I get into any particulars, does anyone have suggestions on
- o development strategies (wrt drivers & nubus boards)
- o development tools ( " " " " " )
- o Interrupt handlers for nubus interrupts ( sIntInstall )
- o development texts
-
- In particular, I find my program crashes and the stack appears to be junk.
- The PC is set to a known, but completely unreasonable value and I have
- no way of finding out how it got there. I suspect it has to do with the
- interrupt code, but I'm not sure. I don't really know what tools I should
- look into to locate the bug. The Think C debugger is pretty useless and
- I haven't had much success with MacsBug either.
-
- Mostly, what I really want are techniques that you might have used when
- developing device drivers using nubus interrupts. Have you found a useful
- tool for such development?
-
- Thanks.
