When I use the newlib type footprint, TSSOP-65P-640L1-20N, Luciani made
to my 74HC245 schematic symbol I have problems generating a netlist
and pcb.
I've been working with this problem for a couple of days trying to find
out why this element is being treated as an M4 footprint. Based on the
error message this is what I believe is happening. When I run gsch2pcb
it generates the following error: "stdin:58: /usr/bin/m4: Bad expression
in eval: /2". If I let it keep running it will eventually print to the
console "/bin/sh: line 1: 21526 Killed /usr/bin/m4 -d -I.
-I/usr/share/pcb/m4 -I /etc/pcb -I$HOME/.pcb -I.
/usr/share/pcb/m4/common.m4 - >> caspian.pcb" before finishing the rest
of the schematic.
I'm looking for some help in debugging this problem. Is there an
intermediate step I can run to try and figure out if the problem is with
the footprint or my schematic? What triggers the m4 library to kick in?
Are you sure that the footprint attribute is not misspelled in your
schematic?
You could try creating a schematic with a single HC245 with the footprint
attribute set to TSSOP-65P-640L1-20N and run the command ---
gsch2pcb --elements-dir ~/projects/gaf/pcb-elements/luciani
TEST_SCH_NAME.sch
(* jcl *)
When I created the test schematic I had the same problem. However this
time I also added the original 74HCT245-1.sym from the gEDA symbol
library and assigned the desired TSSOP.. footprint from Luciani and it
worked fine! So the problem is in my modified version of the
74HCT245-1.sym. I modified the original version of the symbol so that I
had the power and GND pins on the symbol rather than defaulting to the
nets defined in the symbol. I also moved some pins around and deleted
the default footprint of DIP. Thinking that every symbol must have a
default footprint I assigned the default to the desired TSSOP... and it
still failed.:) I did a difference between the original and my version
and I don't see anything obvious. I ran gsymfix.pl which modified it
but didn't fix the problem.
So at least we have it narrowed down to the symbol. So what could be
wrong with my symbol that would cause an M4 error?
Note:
I attached my modified version of the 74HCT245-1.sym.
Thanks for the help,
Jeff
