To understand how to write a driver and how the code works, I started
writing some doc about it.
Please comment.

structure to make up for the differences, one could possible
copy parts of the openocd parport driver, which has such a structure
for all the parport adapters.
Which .c file do you recommend as a starting point to code for
my adapter ?

But how do I update po/urjtag.pot ?

A think, technically, jtag operations and cpu operations are
independent, but what is urjtags stance on srst ?
This adapter has a srst line, should the driver let it b
rjag care wheter you reset the cpu or not ?
Since I cannot find any information how urjtag handles srst in the code
(didn't try very hard though), my guess is that it simply is ignorant
about the cpu state.

I'm looking att src/tap/cable/wiggler2.c, and I'm wondering what
PARAM_SIGNALS (cable) is for...
It is defined in src/tap/cable/generic.h, which is only included from c
, the typedefs are completely unnessary,
and removing them would benefit the understanding of the code.

Found the problem,
I did:

when I should do:

solve this mess as fast as possible, treating this code as you want to
do it is in my opinion just a waste of time (well, apart from learning
to write good commit messages...). And I don't need to get my patches
to be accepted upstream, I'm content to just have them applie
e setup is just a cache of the
above
. if you miss a file, you can get it from mfg. or from e.g.

I come up the the attached code.
The urjtag file has three columns:
$ grep Hitachi data/M
ond col.
is used to find the PARTS files:
line 388:
strncat_const (data_path, id_name);
strncat_const (data_path, "/PARTS");
e.g. data/analog/PARTS.
One way to handle this is to use the id instead of id_name for the
parts directories: e.g. instead of data/a
