I am trying to bring up a Board using the ATSAMD20E15 But, I am getting an error from the programmer:

Error could not activate interface. But found a DAP with ID 0xbc11411

This just in, when using the "Device Programming" tab/window I can uncheck the erase flash before programming and verify after programming, then I am able to program successfully and verify. It still won't program from the "Debug" button.
Thanks in Advance. This maybe a dup, I tried posting before.
