Hello,
I posted a similar patch several month ago.
I have a JLink version v3.0
To get it to work you have to change several little things.
This is just a very ugly hack that somewhat disables support for >=V5 JLinks
I'd just be interested if any of you can also get it to work this way...
I would like to build a clean version of this patch that doesen't break the
rest of the system, but I'd need some more help as I'm not experienced in any
openocd/jtag code
If you're interested I can explaine all the things that I needed to change...
