Is my hifive1 board crashed?[SOLVED]

Hi,
I tried uploading RgbLedfade from arduino examples

I am getting this following error

Hi Daniel,

As far as I know there is no software support for HiFive1 or HiFive1 rev B in Arduino IDE.

Please see SiFive’s IDE software named Freedom Studio here: https://www.sifive.com/boards

I could see the error from freedom studio console also,after trying to upload some sample programs like RGB fade or blinking.

Tried uploading the program after entering into “safe boot” mode by pressing the reset button right away when green led blinks for half a second.

Reference: Hifive1 getting started guide under HiFive1 Boot Sequence title.
