Thank you for replying.

That's what i thought also. But after I erased the SD and pasted correct files, it stopped working, and Yat keeps looking for port and then says it's busy.

That's usually a Windows issue, so you may need to reboot Windows. Make sure you don't have Bossa and YAT loaded at the same time.

I've tried prontface, but no comm also. I've also uninstalled and installed everything again, but nothing.

I've attached a screen shot.

@amcutem did you also put a config.g file in the SYS Folder?

[amcutem]

@Dougal1957

Yes. I've done all that. Anything else?

? elaborate please, it doesn't make sense to be bossa or duet and not have communication - you need bossa software to communicate with bossa bootloader in the duet to make the board appear like a duet again. does that work?

[DocTrucker]

Some of the older bossa/duet guides didn't mention explicitly specifying the com port in the command line argument. I needed that when I did it.

Sorry for the mistake.

It actually just shows bossa.

After writting the firmware, COMBINEDFIRMWARE, and shows success, it still shows as bossa and not DUET,then, nothing happens when i connect using YAT. Sometimes it connects, but no response from the board when i type a GCode.

Right now im trying to learn about jtag and if it can help.

Is there a duet repair place i can send it to?

Its a bummer if its shot already cuz its new.

First try the command line version bossac, it'll rule out checking the correct boxes and resetting the board

assuming a normal windows install, with the firmware in your Downloads folder, run in a command prompt:

cd Downloads
"\Program Files (x86)\BOSSA\bossac.exe" -e -w -v -b RepRapFirmware.bin -R

you may have to specify the serial port to use like so:

"\Program Files (x86)\BOSSA\bossac.exe" --PORT=COM5 -e -w -v -b RepRapFirmware.bin -R

if your folders are different, adjust so the paths are correct.

isn't the 0.8.5 board old? not sure the people who fix acurrent Duet is too familiar with the first generation, but Duet3d themselves may try, however you quickly get to the point where its cheaper to buy a new board.

edit; updated with correct firmware as pr Ians input.

onnect using YAT. Sometimes it connects, but no response from the board when i type a GCode.

as long as the board shows as bossa it will not respond to gcode, this is the bootloader for the duet and can only be used to flash the firmware.

if you're getting the bootloader odds are you will not need an external programmer.

@amcutem the “combined version” of the firmware is for Duet 2 WiFi and Ethernet. Use the ‘RepRapFirmware.bin’ from 2.05.1 and 1.26.1 release for Duet 06/085.
