JTAG No Video, Sync = Corrupt NAND?

[Mikebyrne]

I have a jtag in for repair which was working but now it has a single green power liight and no audio or video?

I also cannot get the controller to sync with it?

It is a xenon with a ethernet cable soldered to various NAND reading solder points.

I've tried a reflow with no joy, what are my options in relation to connecting the ethernet plug?

Is it just a matter of connecting that directly to the PC/Laptop and reading it? I've never seen this before

Flash XeLL / Xellous to it. If it boots, then it's not likely to be hardware.

 

[Mikebyrne]

How do I connect via the Ethernet jack that's soldered already?

 

[Martin C]

Remove it?

It can't be that hard to solder an SPI programmer / NAND-x to it.

 

[Mikebyrne]

I was just curious as to how to connect to it. I've never seen it

Do I need a Ethernet to LPT connector for it?

 

[Martin C]

Depends on how they had it wired up the other end. It's just a CAT5 connector

no has to be connected to LPT or USB port

Get Jtag Tool BY Coolshrimp it will show you how to connect it

Of course it does - what a pointless comment.

CAT5 refers to the connection type, not the kind of data.

Maybe I should have put RJ45 which is its proper title.

sheesh!

I might just bang my Nand X into it instead, Didnt mean to start a fight!!

I was just curious as to how to connect the "RJ45"

 

[Mikebyrne]

Is it possible to snip the wires connected to the RJ45 and solder the wires of the nand x connector cable directly to them as opposed to the solder points?
