Hi Scott, 
Thanks for the reply. I think I have seen these documents but I can't
find a diagram for t
he cable itself. I was hoping someone could take a look inside to trace
how it connects in both ends (debugger side and target board side). I
can't find a diagram anywhere.

Thanks and regards,
Jon

Jon, I thought the information you need is in app note 10010.pdf.   But on 
checking, it does not show the cable pin out, only the JTAG connecttor 
pinout.  I took one apart and it is hand wired inside the shell.  It does 
not look like a 1 - 1 match either.

Email me direct if you need a copy of the pdf.

Hi,

I am looking for a schematic/pinout diagram for the 20-pin arm cable 
(CA-ARM20 / CK-ARM20) used by this debugger. Does anyone have it?  
If I am not mistaken it's a simble DB25 to 20-pin header cable. I 
can't find a pinout for the DB25 connector that connects to the jtag 
device.

Could anyone do a trace using a multimeter and post a pinout 
diagram? Please help.

Best regards,
Jon
