Ahhh!   Maybe I should check that......

Right now, I'm assembling Boot with no errors and Krn is giving me a few; maybe 15-20.  I'll have to go look at the repo again. When I looked in the defs folder today (well at least ONE of the defs folders) the defs files I mentioned were nowhere to be found.

The labels in the code are setup to be longer than 8 characters, which asm in Nitros9 ignores everything beyond.  Even if you get it compile you will get multiple define errors.  The DEFS files are in the repo under defs folder.

If you go into the Pin Planner it should show you a diagram of the FPGA and then below that there is a section where you can see all of the pin assignments. You should be able to scroll down to the bottom of that section and double click on <<new node>> to make a pin assignment.

I am using some defs files that someone else gave me on a boot disk image but when I try to assemble the Krn module it is choking on terms like "D.MLIM", "D.FMBM", "D.BTLO", and a few others.  I have fairly recent defsfiles (2011) and the defsfile uses os9defs, rbfdefs, scfdefs, and systype.  Am I missing anything?

>>>>>> Just something else I thought of:  When starting a project out from scratch (i.e. CoCo3 or 6809 core on FPGA) there are some things to take into consideration when assigning pins to devices.  The Altera FPGAs are divided into physical banks and Altera suggests that the high speed signals such as address or data lines be grouped together within a bank or adjacent banks if at all possible.  Also, at least on some devices, there are certain banks that they consider more well suited for high speed stuff.  If you do a little research on the 'net you'll find some notes on this in the design considerations.
