I downloaded and installed IDE 1.8.0 on my Raspberry Pi 2 Model B running the latest Raspbian Jessie.
Works great with my UNO board.
I am unable to use it with my Zero board.
Under Board Manager I selected "Arduino SAMD Boards (32-bit ARM Cortex-M0+) by Arduino" when I clicked "Install" next to "1.6.11". I got the following error:
"Tool CMSIS-Atmel is not available for your operating system."
What can I do to fix or work around this?
