    Edison stuck in re-boot cycle after downloading PWM app to MCU

    cayeric

      Hello Intel Developers,

      with success i managed to flash an LED connected to an GPIO from within the MCU.

      When i tried to access the PWM, on the other hand, and download the App (build without warning/error) from the MCU SDK, my Edison device gets stuck in a re-boot cycle.

       

      Has anyone a clue what was going wrong by looking over these boot/error messages?

      Application available at (physical) address 0x04819000

              VRL mapped to 0xff213000

              App size = 11908 bytes

       

              App Authentication feature is disabled!
