My first steps with LinuxCNC - comments appreciated :) Using Mesa 7i80 and 7i78

You mentioned using Xilinx to create your own bit files.  How do I identify the appropriate .xise file to start with?  I have a 7i92M Mesa Board.  I would like to customize the pinouts to best use a breakout board that I am using.  Also, can this be done only using Mesaflash?

Thanks,

Bill W.

Did you download the support zip file from mesanet.com it has a lot of ready made firmwares for different BOB.

You would use the seveni92.xise project

Mesaflash is used to write and check the bitfile you created with the Xilinx tools

I did and I could use 1 or two of those configurations with some work arounds with the wiring but it would not be ideal.  I thought it was a good time to learn a bit more about the process.

Thanks for the reply!

Thank you PCW.  I should have figured that one out.

Note that you can trade off special functions (stepgens, PWMgens, encoders etc) for
GPIO  in the hal setup so the pre-made configurations are more flexible than they may
appear at first glance.
