Can JTAG be used for debugging ?
Yes, the JTAG can be used for debugging. Check out the JTAG connector page.

Note: one shouldn't generally need JTAG access these days, unless you accidentally nuke your own flash. Or if you're porting your own OS to the gumstix.

gumstix engineering uses &quot;the wiggler&quot;, a Maccraigor product with the macgraigor software, called OCDemon.

The usb demon product for the Xscale processor is also useful. The only difference is how the product is plugged into a host computer.

If a reflash is needed, you can get this done by gumstix with the reflash program.
