I got throu i think 5 pages of this discusion so far but if i don't find it here i think it's safe to ask ^^. Thank you in advance. I'm a bit baffled if i should repair it or repurpose it seeing how hard its to find good info on parts etc but we'll see.

Edit: Forgot to clarify i meant U2 on the main board

I had some spare time to poke at this a bit more.  I was able to modify the bossac utility to connect, read, and write to the flash.  I erased the flash, wrote the firmware bin, verified, and set the boot mode to flash.  However, I'm still not getting a bootable printer at this point.  Not sure what the deal is.

Hey! I know I'm a tad bit late here... But how did you modify BOSSA to write correctly? I am connected successfully to my davinci mini w+ board and can read from the board but cannot write to it, it just fails with a 'SAM-BA operation failed' error. Could you share your custom BOSSA version, if you still have it?

Hi, I know that xyz da vinci jr printers are probably scrapped already but maybe anybody could help me to recover my Da vinci jr 2.0 mix?

I erased flash sad

Have no dump, no idea how can i unbrick it.
Maybe anybody have atmel dump for that printer? or is there any way to port repetier fw for that printer?

Probably too late but do you still have the issue? If you do so, i can probably try to help you with that.

I have not change RepRapFirmware to drive LCD yet, the LCD lights up, no black bar but no display either.

It's 2021. taking a shot at this. going to use klipper, since it handles multi-mcu systems.

This card uses the same MCU that the Printer Da Vinci Jr (ATSAM4E8E)
Here you can see a process to load the firmware:

using a tool Atmel:

Even this card is for 3D printers

Great help thanks, I got this installed on my junior and now changing pin assignment and LCD support...
When I plug the junior usb it starts OK reporting Duet 3D printer control electronic (COM4) and the lights inside printer comes on... But LCD still has just two horizontal bars...
This is fun, I will update daily until full conversion is done...


How did you manage yo upload duet firmware to the jr board? Any advice or tutorial? how did you put in bootloader upload mode? Jtag? Programmer?

Also have a printer I am willing to sacrifice for testing.
