I have built Openocd for Xscale debug. Does anyone know Openocd configure file for debugging Xscale? I do not know what I need to set in below item:
#jtag scan chain
#format L IRC IRCM IDCODE (Length, IR Capture, IR Capture Mask, IDCODE)
jtag_device 4 0x1 0xf 0xe
Above is the setting for ARM7 and ARM9. If I use above values, it seems that Openocd can not be initialized properly. Does anyone know which values I need to set if I would like to debug Xscale? Thanks!

XScale support is still work in progress, and only little useful work can be done with it at the moment. The latest code in SVN (branches/xscale/) only knows about PXA25x, I’m currently working on generalizing it for PXA2xx and IXP4xx. I’m close to getting it all working, but I can’t say for sure when it’ll be available.
The jtag_device setting for PXA25x would be:
jtag_device 5 0x1 0x1f 0x1e
PXA27x, IXP4xx:
jtag_device 7 0x1 0x7f 0x7e

Dear Dominic,
Thanks for your reply. My target board is IXP42x and works on big endian. I will try the information you mentioned and wait for new release availiable. Thank you!
