[gentoo-embedded] JTAG (Linux) article

[wireless]

Hello,


There is an article in the September 2010 Embedded System
Magazine, which features a story about how to use a JTAG
(less than $100 usd) on an embedded linux kernel for debugging.


If anyone is interested, drop me some email and I'll forward
the zip file to you:

cmp_esd0910_pdf.zip

in case you want to search in out for yourself.

Several folks have asked for the zip file.

The device/article are based on software, found in portage
(very cool, but a version bump is needed)...

There haven't been any more upstream releases, although there is
definately upstream activity. I guess a git ebuild would be nice.. :)

It's actually available from the publisher already. Look for a link
on http://embedded.com/ down in the right column.

"PDF of ESD's Digital Edition."

http://openocd.berlios.de/web/?m=201002
this shows version 0.4.0:

OpenOCD v0.4.0 released Monday, February 22nd, 2010


ARM looks to be the most active platform for openocd

portage has version ~0.3.1

Oh sorry! I forgot that not even 0.4.0 is in portage. :\ But I do
suggest a git version. Upstream development is pretty stable.

And! There *is* a git ebuild already, from March. I guess just unmask
it and emerge.

echo 'dev-embedded/openocd **' >> /etc/portage/package.keywords
emerge openocd -av

Yes you're right, ARM is the major platform and works well, but I
don't believe it is meant to *only* do ARM.

i guess someone should step up to be a maintainer for openocd.  i have no 
personal interest in it as we use urjtag at my job, so that's what i watch 
over (up and down stream).

I'm a gentoo user and also an openocd user.  I'm also an openocd contributor,
mostly bug fixes on the xscale target.  I'm not a gentoo developer, but I've
been using it for many years.  I'm able and willing to help out, if someone
would be willing to sponsor / mentor me.

Thanks,
Mike

Thanks for the offer. openocd is only one package, so it's best to have
somebody proxy maintain it. Personaly I've always used the openocd-9999
pkg.

Yeah, development has been brisk and it has improved quite a bit of late.

Thanks,
