Trouble with JTAG pinouts

Hello Friends, I have screwed up my uboot unfortunately, Now the unit just blinks and turns off at power on. I thought Serial connector would be enough for these sort of issues, But as i have read it isn't of any use without uboot. I've already tested, cant establish a serial connection.

Now I need to attach a JTAG port, I've read the instructions on the wiki, But I cant quite figure out the details. I have decent soldering skills, I've already attached serial port and replaced the power button and jack. So it would be great if someone can guide me on getting the JTAG work.


My DNS 323 is of Revision B1, was running Debian Jessie/Sid with kernel version 3.11-rc4 before getting bricked. I tried to replace Orion5x uboot. :'(

This is the Wiggler cable i have, with 20 pin header.

Can anyone post any pictures they have of the DNS323 J-Tag setup ? Do i have to solder the SMD resistors onto DNS323 itself, Before soldering the connector pins? I've already seen the wiki pinout and cant seem to figure it out.

Thanks in Advance. smile
