Is there a place where we can find the precompiled SysupgradeImage file for the Arduino Yun Rev. 2 and the packages?
In the same way these things are available for the original Arduino Yun:
https://arduino.cc/download_handler.php?f=/openwrtyun/1/YunSysupgradeImage_v1.5.3.zip
https://downloads.arduino.cc/openwrtyun/1/packages/index.html
Please!
