             IDE: Atmel Studio 7

        Devices: ATtiny416 Xplained Nano.

                     AT416 that I mounted on a breakout board.

Programmers: On board programmer on Xplained Nano.

                      Atmel-ICE.

 

The problem is the ATtint416 mounted on the breakout board does not enter programming mode with Atmel-ICE.

The ATtiny416 Xplained Nano will program with the on board programmer or the Atmel_ICE. (plug the Xplainded board into a USB "power only" source to isolate on board programmer.) 

 

Is this a fuse setting issue and how would I resolve this when Atmel Studio 7 can't even communicate to the chip?

UPDI is pin 16, not pin 2.

 

>Is this a fuse setting issue

Its pretty difficult to screw up anything in the fuses on these (maybe RSTPINCFG if you only have low voltage programmer like the tiny xplained nano), and probably impossible with an ICE which can get into UPDI mode in any case.

I think Atmel-ICE can't do the 12V thing for UPDI. So some caution is recommended.

Thank you curtvm. 

I made some bad assumptions as to the pinouts between the boards being somewhat similar since the power pins matched.

Should change my user name to RookieForever.

You are right. I just assumed a $130 programmer would do it all.

Currently the only tool from Microchip supporting UPDI high voltage activation is the PowerDebugger. The high voltage activation will also be supported by the PICKit4.

At the point in time when AtmelICE was designed UPDI didn't exist. Adding support for the UPDI protocol was fair enough, but adding high voltage support would mean HW changes. Not so easy.

Speaking of using the PICKit4 for 12v UPDI programming, it's my understanding we are waiting on an update to MPLabX to 5.25 somewhere around the end of July. 

Anyone know if a pre-release is available or some other way to use the 12v UPDI (outside of rolling my own programmer software)?
