See http://community.atmel.com/comment/2304156#comment-2304156.

For us the error was on ATSAME70Q21 (SAM E70 XPLND board): if we did a separate manual erase, followed by a write+verify, then it worked. The flashing error appears rarely for us and in different address locations in function of the resulted elf, but when it appears it's staying the same until we change the code and rebuild the binary: till now the only workaround was to do the erase few seconds earlier as found in the linked comment...
