picking an ARM board with jtag for debugging

[Christopher Harvey]

 I'm looking for an ARM board with a cortex a9 mpcore with a good 
 solution for jtag debugging under linux.

 I have a beagle and a pandaboard sitting in front of me, but the beagle 
 only has cortex a8 and the pandboard jtag situation looks pretty dismal. 
 (You need to buy and download a lot of software). Cost really isn't an 
 issue, (under 1000$) but good gdb support is critical.

 I need jtag specifically because kgdb doesn't start up soon enough for 
 me.

 Anybody here doing ARM linux development with jtag?

 thanks,
 -Chris

Hi Christopher,
why not give a look at OpenOCD? Some guys (me included) have sent some 
patches to support Cortex A9 and Panda. Development version has now 
(basic) support for Pandaboard.
Anyway you have to use development version (git clone 
git://repo.or.cz/openocd.git) since 0.4.0 stable release hasn't good 
support for Cortex A8/A9.
Furthermore, if you use git version you can also contribute to improve 
cortex-A* support, which is always very welcome ;-)
I'm just about to write an HowTo to explain how to use OpenOCD on Panda. 
I will publish it on my site soon.

 Thanks Luca,
 I find it funny that of all the expensive jtag solutions out there, 
 OpenOCD seems to be the most convenient. I will probably try that 
 direction out. Hopefully I will find the time to learn and help out with 
 OpenOCD if I happen to need features that it doesn't already support.
