Marlin to Sav MK1

Hello,

I´m trying to flash my Sav MK1 card with new Marlin. Problem is that when I try to compile anything with IDE I just get that "Arduino.h" is missing... This happens even with bareminium sketch!

Is it possible to flash it thru Teensy 2++ card and use the avrdude to flash it to card?

I was trying to use klipper, but there was some problems with usbdata witch I couldnt solve so I have to change back to "Sound of rattling" Marlin...
