Impossible to flash my Duet wifi
-
I received my duet a week ago, I installed it and configured it, I was able to print but two days ago I lost the wifi and tried to reconfigure it with the Yat but it did not respond or recognize the Duet as an external device, I tried to install the driver again but it has been impossible for what I searched in the forum and I have seen a post in which they commented that the card should be flashed again, I have tried in several ways, with external power, without it, removing all the cables connected to the plate, with two different computers, several cables and it has been impossible, I tried Bossa and the same, I can not flash the board, any suggestions? in the attached video you can see the process.
Thank youhttps://www.youtube.com/watch?v=E76Fq1krF34&feature=youtu.be

What is the file size of the DuetWiFiFirmware.bin that you are trying to flash? It should be over 300Kb. I think your file may be much shorter than that. The download area is https://github.com/dc42/RepRapFirmware/releases.

The sd card must be inserted when i'm flashing with Sam-ba or it doesn't matter?

Your video link doesn't work for me.
Did you check the size of the DuetWiFiFirmware.bin file?
-
Hi, yes the size is 372, try with this link please: https://youtu.be/PNkdRx7adss

At 1:41 in the video SAM-BA reported "Sent file and memory do not match". So programming failed.
Please try using Bossa instead. Instructions are at the end of https://duet3d.dozuki.com/Wiki/Installing_and_Updating_Firmware#Section_Fallback_procedure_Num_3.

This is my Duet i'm using the Duetwififirmware, this is right? -
Yes, DuetWiFiFirmware.bin or Duet2CombinedFirmware.bin from the 1.21 release area is correct for that Duet.
What happens if you write the firmware using Bossa, but after that click Verify?
-
do the windows drivers need to be loaded before the port will be recognised after flashing?
could that be why it isn't being recognised afterwards?
-
I would expect Device Manager to report "Unknown device" if the Duet was detected but no driver for it was found. You do have a couple of unknown devices showing, but they are flagged "Dispositivo base del sistema" which according to Google Translate means "Base device of the system".

If i try to install de driver in the ports you can see nothing happen, i don't know what's that but is not the due because if i plug or unplug the Duet that ports still there and if i install the Duet driver an error message appear. -
Thank you, Bossa is getting verify errors, just like SAM-BA did. Please ask your suppler to replace the Duet under warranty.

I bought it on your web, how can I send the Duet?
