Did you use the TSSOP-65P-640L1-20N? I can choose other footprints and
assign them to this symbol and it works fine for me as well. It's when
I use the TSSOP-65P-640L1-20N footprint I get this problem.
http://www.luciani.org/geda/pcb/footprints/TSSOP-65P-640L1-20N
Yes. I only use the footrpints that are on luciani.org ;-)
The makefile that I use to update the website copies all of the
footprints from my production directory.
Wow, I didn't notice it was MR. Luciani himself helping me out. :)
I only have newlib parts assigned in my schematic. I do however have
the M4 libraries installed on my machine.
Try Stuart's suggestion of using the -v -v option.
If you post your *simple* test schematic that contains the problem I will
take a look. Make sure you use embedded symbols!
(* jcl *)
Here you go.
-It took me a little bit to figure out how to embed symbols.
Thanks for the help.
