Well, I know the subject is not very clear.

I have two original Atmel MkII programmers I'm using since several years.

They worked perfectly until the last update I made few months ago to AtmelStudio 7.0.x (now 7.0.1645).

 

Now, BOTH, aren't reliable anymore. I mean I'm wasting hours to try and re-try until they work for a while. Then after few write cycles stop again. The errors are various, I didn't find a criteria. Some examples:

 

  • the connector seems to be reversed (it's not)
  • Unable to connect to tool AVRISP mkII (Failed to open: MPLABCOMM_INVALID_HANDLE)
  • Failed to enter programming mode. Error status received from tool: 0x03.

 

I don't think it's an hardware issue because:

 

  1. the same programmers on other machines with older AtmelStudio versions work fine
  2. most of the time, it's enough to restart a couple of times AtmelStudio in order to get them back to work
  3. this happens with any board, even with those well-tested or dev boards

 

Is this a "polite" way to invite us to upgrade our tools? smiley

Perhaps it's a joke, but I really don't understand how to fix this.

Few days ago I installed Windows from scratch, AtmelStudio and nothing else - same behavior.

Which Windows (via winver)?

You're not the only one having similar problems.

With one LUFA-based AVRISP2 :

5. Search for similar reports with the original AVRispmkii - it might be some bug in Atmel Studio 7.

I forgot to mention: Windows 7 Home Premium, 64-bit, Italian.

Potentially, a Windows driver update could be the cause though less likely on Windows 7.

 

A guess is the AVRISP mkII firmware in Atmel Studio 7.0.1645 has a defect.

Consider updating its firmware on a functional Atmel Studio 7 then disabling the firmware check in 7.0.1645

Then you can fix it by navigating in the menus of Atmel Studio 7. Go to Tools -> Options -> Tools -> Tool Settings -> Check Firmware -> False. (shown here: https://i.imgur.com/XWjed2c.jpg )

Now try again.
