Hi
this bug is related to my previous bugfix #41357.
I recently started to reuse my old avrmkII to flash ATXmegas.
Every second flashing attempt reports exactly 2 errors:
avrdude: stk500v2_recv_mk2: error in USB receive
avrdude: stk500v2_recv_mk2: error in USB receive
After that one execution works fine before everything starts over again...
Everything works fine. It just takes a lot of time to complete the task.
I recommend to undo my bugfix #41357. usb_reset() removes this errors and
speeds up the deployment. Since my last bugfix everything got updated. Now OS
X does not seem to be sensible to usb_reset() anymore. Well, at least on my
system... Honestly, I have no clue what has changed.
BTW: I am using: avrdude 6.1, latest OS X, and latest avrmkII firmware.
A quick note about the avrmkII->atxmega programming performance:
In the error-less case it takes about 6 sec for the devices to get in sync.
After that it works fast as hell. I don't know whether the processor, the
avrmkII, or avrdude is to blame for. Just wanted to mention this. Here is a
log including some timing notes:
avrdude -px128a1 -cavrispmkII
-Uflash:w:../00_EclipseWorkspaces/AVR/ATxmegaTest/Release/ATxmegaTest.hex:a
-vvvv
