PyedbglibError: Unable to SET (failure code 0x11)

Hi,

I'm trying to connect my Atmel-ICE to my new AVR128DB28 DIP chips on a breadboard. I've never used pymcuprog before, and I'm getting an error message that I don't know how to debug:

I'm getting this error whether my target MCU has power or not, so I suspect it's a software problem on my host machine. Otherwise, I would have expected a "target doesn't have power" error. Is this a correct assumption? I don't want to debug my wiring before I know that's causing the problem here.

I'm using Arch Linux. I've ran everything as root to avoid usb-permission problems as shown above, but things are still not working.

Any help would be appreciated, Thank you

The debugger FW looks ancient (1.0.33, if that is accurate) - you should definitely upgrade using Studio/MPLAB. Also:

• check the linux notes on https://pypi.org/project/pyedbglib/
• we have not qualified pyedbglib for py3.9 just yet, so it might be worth trying in a 3.8 venv
• its recommended to install in "user space" (pip install --user pymcuprog)

[kristianlm]

Thanks for your feedback, xedbg. I'm able to get the target voltage:

klm@pisa ~> pymcuprog getvoltage

Measured voltage: 3.34V

So maybe python 3.9.6 is ok. I tried to hook up UPDI on my oscilloscope, but nothing is happening.

I think I will try to upgrade the Atmel-ICE FW first. It is a bit strange though, as I bought the device not long ago. How old is "ancient"?

[xedbg]

Well, most tools ship with "old" firmware, and the IDEs update on first use. These devices are quite new, and thus need new firmware.

[kristianlm]

Ah, yes that makes sense. I've tried installing MPLAB_X_IDE_v5.50, but I'm unable to find any firmware updating options from the menus. Is it possible to update the firmward using pymcuprog?

[kristianlm]

Success! I tried to create an empty project and with that, MPLAB went ahead and updated my Atmel-ICE. It's now at 1.41.137 and things seem promising. Coming from atmega328p, I'm very excited to go from 6 to 3 pins for programming on my breadboards.

Done.

Thank you @xedbg for helping out!

Good to hear :)
