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:
- the same programmers on other machines with older AtmelStudio versions work fine
- most of the time, it's enough to restart a couple of times AtmelStudio in order to get them back to work
- 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?
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.
