NAND-X Trouble

Alright, I'll resume trying to solve this tomorrow but thought some insight to what could be causing this.

My problems started yesterday when the blue wire came off the connector that plugs into the NAND-X device. Having already ordered another NAND-X on the same day from my local supplier which got delivered this morning.

I cut the wires and made another custom cable (3 metres long) with my usual sub-d 9 pin connector at the end. But when testing it I just kept getting error messages either saying could not find USB device or not compatible with ARM ****** messages.

I know the soldering was perfect, having tested and re-tested and also use multimeter which showed everything ok.

No success so I then picked another wire (2 metres long this time) and re-done the same except this time I just soldered the end of the cable to another motherboard straight away. This time it read the NAND but with errors throughout the read.

Removed the wire and soldered to another sub-d 9 pin connector and plugged it into another box that I done a while ago and know it's working. The same happened, errors throughout the read and occasionally get cannot detect USB device.

Does the length of cable/wire between the NAND-X and the motherboard/xbox has any affect? I suspecting that this is the only cause and will try a much shorter cable in the morning.

The usual stuff checked, device showing in device manager and functioning properly. But what I want to ask, if you use 2 different NAND-X units on the same computer, do you have install drivers again for the other device or shouldn't it use the existing drivers from the first one? The reason I'm asking this is because when I plug the new NAND-X I received today it doesn't show in my devices list under device manger.

Will jump at it again in the morning but if anyone's got any advice on this matter would be really appreciated.

Live long & Jtag everything all :cool:
 
I am not going to go in detail here regarding the length of the wire(s), but the length of the wire(s) definitely causes the flash controller error.

Anyways, as for the driver, I don't think there is any need of installing the Nand-X drivers again. Exactly what do you mean by Nand-X not being recognized? Is it not being recognized as Nand-X or it isn't even showing up in the Device Manager as an unknown device? Also, do the both lights on the new Nand-X turn on when you connect to your computer ?

Hi M8

I agree with Azeem m8, had this issue with my own setup when i tried to keep my workbench tidy the cable was extended and caused me trouble from the start as soon as i shortened it problem resolved. i didnt think the cable length would be an issue it was a m8 who was jtaging cable boxes a while back that suggested the cable length

hope it solves it for you

Thanks for your help guys. Got it all working now, shortened the wire to about 70cm and it worked just fine. Now at least I got 3 connectors just in case one goes wrong.

I will probably just keep the new NAND-X in storage or use it with my other computer but when I plug it in, windows says 'One of the USB devices attached to this computer has malfunctioned and windows does not recognize it'.

As soon I remove it and plug my old NAND-X it just shows as normal in my device list 'PRUFTECHNIK USB DEVICES/XECUTER NAND-X USB'. I think this might to do with port conflict.
