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. -C
