Title: DAP-1160 (RTL8186) JTAG recovery
Post by: tnapul on January 25, 2011, 09:03:55 PM

Hi all,
I have a dead DAP-1160 (RTL8186).
I would try the JTAG recovery, so I compiled

-) includes-0.4.2
-) readline-5.2
-) jtag-0.6-cvs-20051228

under ubuntu 10.10.

I have the cable DLC5 Xilinx.

The problem is: I do not know how to enable the JTAG mode on the DAP-1160.

At jtag prompt:

jtag> cable parallel 0x378 DLC5
DLC5 Initializing Xilinx JTAG Parallel Cable III on parallel port at 0x378
jtag> detect
jtag>

I understand that I must set a pin on the 147 on the RTL8186.
but I have no idea where is on the DAP-160 PCB.

Any suggestions?

Just for the record: I recompiled under cygwin according with the most common setup, but unfortunately I'm still here:

I do not know how to enable the JTAG mode on the DAP-1160.

Here http://approsoftware.com/download/rtl8186/doc/SDK/RTL8186spec_preliminary.pdf (http://approsoftware.com/download/rtl8186/doc/SDK/RTL8186spec_preliminary.pdf) I found something about enabling JTAG mode (pin 147 on), but I have no idea where to put my hands on the PCB..

Obviously I'm waiting for suggestions ..  :)
