Hi,

I'm a bit confused on JTAG headers, so your help is greatly appreciated,
I've got a beaglebone black and I will buy a pandaboard ES as soon as I
find what is the best device to be used for JTAG debugging for both boards.
I need to develop a small research based kernel & I have found Olimex
TMS320-XDS100-V3 , TMDSEMU100v2U-14T and TMDSEMU100V2U-20T.
As far as I have understood, TMDSEMU100v2U-14T is the recommended version
for Pandaboard-ES due it has 14 pin TI or cTI header (?) and
TMDSEMU100V2U-20T is suitable for Beaglebone Black due it can have a 20 pin
header TI after manually soldering.

The olimex TMS320-XDS100-V3 can be used for both boards but I'm not sure in
this and I want to buy one device instead of buying two devices if it's
possible.

Thanks for your considerations!

Mahdi

I'm not current on the latest black but will share what I know. The white
had a built-in jtag on the board no connector required it access was by
plugging USB cable into and CCS recognized it. The first black required a
Soldering of a TI ARM connection onto the board and the XDS100 plugs into
that header .I'm guessing the versions of the V2 are for different ARM jtag
header either 20 pin or 14 pin check what's on the black you have its
unpopulated. Ask Gerald in the beagle bone forum about connector. On the
Panda TI had internal wiki on how to debug uboot and a Linux kernel with
lauterback I don't recall many using this for the kernel it was nice for
uboot. You don't mention how you plan on using your jtag what code ie
kernel or uboot your focused on wether you plan on using open source
tools. Good luck. I find these tools invaluable for bare bone or using
RTOS V2 was very inexpensive. I'd start with the TI development wiki for
Sitara for Linux EZSDK it has a nice tutorial for bare bone and Linux but
last time I played with this was 3 years ago and the kit used a a version
of Linux that might not match your tools. Loading symbols and pointing to
source codes are the keys. Other challah gesture are gel scripts to
configure the SOC. I swear by jtag for debug but I don't do Linux kernel
too much overhead

You can obtain multiple R-Pi boards for the same price of a pandaboard.

Do grab the uboot code and add to it or have it launch your kernel.
One important point is how quickly you can edit, compile, load your
test code. The uSD card interfaced boards seem more reliable than
my pandaboard SD card connector.

By looking at the published data of all three you should
discover how to get there from where ever you start.
