Atmel Start ... sigh.
I wholeheartedly agree!   To work around a lot of those problems I find myself loading the project back into START, making changes or adding components, exporting the source...

reconfigure START for a different processor?

MAC Addresses: down-converting EUI-64 to EUI-48?
So we reached out to our local Atmel/Microchip rep.  Their answer is NO, shortening a EUI-64 down to a EUI-48 when the middle bytes are something other than 0xffff or 0xfffe...

SAMD21, AS7, ASF3.44: Complier setting
The -std=??? option allows you to define which standard the compiler conforms to when generating code.  The default with Atmel projects is -std=gnu99 which includes GNU...

SAME70 HSMCI SD low data throughput
I'm seeing speeds closer to 3.4 MB/s read, 3.2 MB/s write using the Atmel START raw demo, a SAM E70 Xplained board, and a 8GB SDHC card.     Download the...
