I've got a bucket full of jtag stuff that some dildo hasn't paid for
so I guess I can give it away. You'll have to wait 'til I get back to
Sydney tho. Warning! J-tag cables are much beliked by fluffy doggie.

As far as I know, ft2232 chips and their variants may work, but I have only
tried it with the Sheeva plug.

There are still some (hopefully minor) issues, but I have fully

I'll finish cleaning up and start with the filesystem. For the

I am not sure this fits into a /proc kind of interface because
JTAG lets you access the bare hardware. Nemo has just pointed to me
that a process is not the
same as a running kernel, and maybe the abstraction does not fit that
well.

FWIW - the BGDBFS stuff had some aspects of this. I never quite got
to the point of targeting it with acid though (particularly not
multi-node). It would be an interesting extension, but IIRC it would
also require some pretty invasive changes to ACID (or I could have

What a great page!
(I see that it mentions 'urjtag' near the end, which I'd encountered
in trying flash my Altera with an ordinary parallel port. It has lots
code for many disparate devices in cvs, including mine, the EP2C8.)

Could one (is is this the plan) to generate a /proc like virtual file system

I just ran into the following FAQ and info that might be of help:
a JTAG FAQ: http://hri.sourceforge.net/tools/jtag_faq_org.html
interesting detail:
TAG specification is in Std IEEE 1149.1 (costs about $100). I don't
have it. Please search at internet for some JTAG related documents.
This is g
I've used JTAG to debug and program a couple of embedded systems. I
even had an automated regression test suite that tested some AVR
hardware using gdb running on Gentoo talking to an JTAG. Freaky but
fun.
If I recall correctly many chips will allow you to see and twiddle
internal registers
I am intrigued, what facalities would jtag software provide on plan9,
is the idea a virtual filesystem which would communicate with a fairly
dumb jtag interface connected to (say) a PC's printer parallel port,
or may there is some standardised USB interface?
I jse jtag probes from time to time but
Yes please.CDM-64 has a jtag everywere you look.
I recall that a pitcher of Blue Moon at the Fun House makes Gorka happy.

At the latest IWP9 I caught wind of interest in getting a JTAG file system
added into Plan 9. There were more details than just the file system and USB
connectivity that are still a little foggy. At first I didn't show to much
enthusiasm but things have changed in a few short weeks!
