If I plug-in a SAMD20/D21/R21 board while AS6 is already open, it probably won't see it - I will need to restart Studio.

I say "probably" because sometimes (very occasionally) it does see it!

This is specifically 6.2 beta, but I'm pretty sure 6.1 also did it.

I thought I'd seen this posted before, but couldn't find it.

Try 6.2 full, the USB detection was changed to avoid this issue...

So it was a known issue, and has been specifically addressed?

I'm in the middle of stuff at the moment, so not convenient to update - hence still on 6.2 beta.

But I do have the "full" version on another machine - will try it...

Among others. The USB event of 'connected' has a tendency to arrive before drivers have been registered, causing the detection to bail. Now there's a timed retry for quite some time to cater for the driver registration (think we check each couple of second for 5-6 minutes after a connected event is sent by windows).

In addition to that, there was a race/lock condition in the detector. Part is that serial numbers are not available on connect time, but on driver enum time, but there's a long story of windows screwing (changing) how detection is done (think we are on the 5th or 6th iteration of the detection system).

Despite its best efforts to frustrate all progress, I have finally managed to get the project updated to work with 6.2 full (6.2.1153)

I think the board detection is better - but it is still pretty flaky!

You do know that 6.1.1520 not 6.2.1153 is the latest issued version don't you? (aka "SP1").

It is now, but wasn't at the time I started this thread. Nor even at the time I started trying to do the update.

 

Question about the SP1 here: https://www.avrfreaks.net/forum/a...

I've just run-up Studio 6.2.1502 - aka "SP1" - and then plugged-in an R21 Xpro.

 

It has not been detected.

I think it needs a "rescan for tools" option...

In fact, SP1 seems a lot worse!

 

It doesn't detect the EDBG being plugged-in while it's running, and often doesn't even see it after a restart!

(despite the fact that the ATPROGRAM command-line utility can see it fine)

 

angry

 

At least the beta would reliably see it after a restart!

There's recently been an update. 

 

It does seem to be better now - but still not entirely reliable.

In that situation, I found that it needed a complete restart of the PC before the board would ever be seen again.

Yes, it is very much better now - only very rarely seeing problems, and then just a Studio restart fixes it.

I still think a facility to manually initiate a scan for tools would be useful...
