Any ideas?

@usbbdm
There seems to be no reason USBJTAGNT cannot detect flash?
Working fine with tjtag and dlc5 cable.

Looks like you have all the information needed to create an XML for that Target.

Could be one of the two reason.
1. The XML file is not right.
2. Small adjustment of software needed for the CPU. Not the flash

So far it is not cleared to me which is the case. I need to do some study before I can not
say for sure. Which XML template you copied from?
Can you try one of the two?
1.enter debug on mode and detect again.
2.enter trap on mode and try again.
3. Try lower JTAG clock.

from your tjtag experience, looks there is a init sequence needed for XML.

If you want I can take a look remotely tonight and see if we can fix it that way.

Sure I will meet you in chat tonight...what time?

I already tried "debug on", "trap on" and "fullpracc 1" modes and slower speed before I ask for help. Nothing detects flash.

It must be memory init in the target xml. I made the target xml myself, but I do not know how to add correct inits. Perhaps you can show example for everyone to learn.
Here is tjtag source http://sourceforge.net/projects/tjtag/f ... 0.2-Final/

No that is not source code.

[merkin]

Source is included in this "tjtag" version
http://sourceforge.net/projects/tjtag/f ... urce=files

Also this "zjtag" includes source (same author as tjtag)
http://sourceforge.net/projects/zjtag/? ... ecommended

But I think openwrt firmware has good documentation for ar5312.

Apparently you were already offered donation with this cpu.

Here are two interesting posts about inits for other apps

Do you still want to try teamviewer?

Why not open AR430W and copy these lines?
