I hope this question is OK on this forum because I am actually asking about an Arduino Feather M0. Please feel free to remove or close the thread if it is not. I am also discussing this with the Adafruit forum.
I am trying to use bossac.exe from the command line to upload an Atmel Studio 7 bin file to the SAM D21 via USB since I don't yet have an outboard debugger (and the pads are no longer accessible because i prematurely hard-soldered the Feather onto the project board). When I run the command, however, it just hangs with the cursor blinking on the line below the command. I've tried a number of switch combinations that I've found in the bossac help and here on these forums but without success thus far.
If anyone here familiar with bossac.exe and its various settings could provide any insight, it would be most appreciated.
Asking about the Feather M0 here is fine. The problem is cross posting on two different forums. This can lead to duplicate effort by people taking the time to give the same answer that you already received on the other post. If you are going to cross post you should at least add a link to your other post so that people can see all the responses you received.

Sorry about that. Here is the LINK to the other forum. I was cross posting because I knew bossac.exe - as used by the SAM D21 core and Arduino IDE - was forked by the Arduino team, so I was hoping there might be more familiarity here with that specific tool.
