This could be caused by several reasons, for example the USB port you are using could be not providing enough power for your board to operate correctly. So, you might be able to get better results by using another port or even better an external power supply. Other option is that the driver installation was not finished correctly or something went wrong during its process. So, you could try re-installing it to see if your PC is able to recognize it after this.
You could try using the other USB port to connect to the Edison's Linux terminal with PuTTY and see its booting process. You could check if it has any issues or if it is rebooting itself. You can learn how to connect to the Linux terminal in IoT - Setting up a serial terminal on a system with Windows* | Intel® Developer Zone. Let us know if you notice anything strange.
I tried to supply the external power and used terminal to see the booting process. I got the following result in my booting process, but If i press enter twice it is not letting me to enter to shell mode.
Is it the expected response we should get when we reboot the intel edison board??
thanks in advance,
It looks like your Edison has a software issue. There are a couple of things we could try to recover your board. First you could try to flash the Edison's image with the Flash Tool Lite which can be found in IoT - Intel® Edison Board Download | Intel® Developer Zone as well as a guide on how to use it. If that method doesn't work, then I suggest you to try the flashall method. Try them both and let us know what happens.
