http://www.usbjtag.com/jtagdevices/sbv4200.php for SBV4200 layout.
As of USBJTAG NT layout, user manual pdf has it.
Also can be found in here.

Here's what I got for the header:


1= trst(didn't see this in pix)
2= grnd
3= tdi
4= grnd
5= tdo (jumper to r37)
6= grnd
7= tms
8= grnd
9= tck
10= grnd
11=reset(didn't see on pix)
12=(not shown on layout)
13=debug(not used)
14= no connection

vcc,grnd,tx and rx shown.Are these used for serial rs232 and not ejtag?

Can someone verfiy and correct this info if necessary?

Is some JTAG implementation, RST is optional (Most modems does not have this pin). TRST is optional too as long as you are sure if it is pull high.

13=debug(not used)
14= no connection

Pin 1: not used
Pin 2-10 shorted together and connected to grnd at J4
Pin 3:connected to TDI
Pin 5 connected to TDO via jumper to R37 on bottom of board
Pin 7 connected to TMS
Pin 9 connected to TCK
Pins 11,12,13,14 not used

Looking at pix with header. Pin 1 is bottom row 1st pin on left.

This is just to further hard work (already done).

I read and saved cfg,firm,boot and dyn.
I changed mac in the cfg and tried to reprogram using
ldram cfg
program cfg
and get bad command or script?
used sprogram cfg and worked

[usbbdm]

USB JTAG NT has removed "program" for SB(V)4x00. So use erase and sprogram.
