No communication after erase button pressed
-
Have you tried with and without VIN power applied?
-
@dc42
yes , I have tried this , it makes no difference. -
If the following are true:
- you have already tried pressing Erase again for one second followed by Reset as I suggested earlier;
- you always get the "Device Descriptor Request Failed" message (not "Unknown device")
then if your Duet is still under warranty, ask for it to be replaced.
-
Both of those are true. What does this mean happened ?
My duet is no longer under warranty.
I would be quite disappointed and angry if I should buy a new one.
-
If all you did to create the problem was to press the Erase button, then it should be possible to reprogram it. Have you tried a different USB cable?

Also tried a Linux pc , no luck.
It might be helpful if you included the dmesg part around the time you plugged it in, and an lsusb after you plugged it in

Yes , I have tried a few different cables.
Should I have the sd card inserted or not ?
It doesn't matter, unless the SD card is faulty and drawing a large current from the 3.3V rail.

Noted. I have been trying without the SD card anyway, so what is the next step ?

Did some digging,
and red that this message usually means that the device has exceeded the current limit of the portit means some general communication error, but either way it is worth a tryI, provided I have a notebook, would try to remove the sdcard, give the panel external 12/24v power, unplug the notebook from the charger and any other device connected to the mains voltage, and try the connection that way.
And / or an usb cable with multiple computer side connectors used by some mobile hdds.
I really do not know if it would help, but it is worth a try
-
Ok , so I just tried this , still no luck. I also tried running through usb isolator.
-
So what are the next steps ?
-
Which country are you in?
-
I am in South Africa , Pretoria
-
Unless you have someone local to you who may be able to diagnose the board, your best option may be to arrange with forum user W3DRK to send the board to him (he is in the US) and take a look at it. he is experienced at diagnosing and repairing Duets.
-
Can you assist me with a jtag reflash ?
-
Reliable shipping to USA and back would cost me quite a bit of money. Buying a new one would be a better bet for me.
I would really like to give the JTAG reflash a go.
What programmer do you use for flashing over JTAG ? and can you provide me with a wiring diagram ? Also , what binary should I flash ?
-
We have never flashed a board using JTAG, we flash using USB.
The symptoms you report are odd and it sounds to me more like a wiring or driver issue, except that you have tried multiple PCs. Have you measured the voltage on the +3.3V rail? Is any of the chips or the WiFi module on the Duet getting hot?

3.3 v rail seems good , the SAM chip is getting a little hot , around 40 degrees , the esp is ice cold.
Just another thing I noticed , if I press the erase or reset button , nothing happens , no flashing of any LED's
