Open source ARM Debugger
By needjtaghelp
I am a software guy, so I am a novice at this. I would like to dump the firmware from a device I have. The device has a daughterboard with an XScale PXA255. I can see the 7 pin JTAG header and I have the documentation which lists the pins as TCK, TDI, TDO, TMS, nJTAGTRST, GND, and nRESET. What hardware do I need to talk to this? The products I've seen mentioned in this forum as compatible with PXA255 no longer seem to exist. Once I have a suitable JTAG debugger, I just compile and fire up OpenOCD and everything should work? Any help is much appreciated.
