I am using Dragon board 410c which runs linux (linaro alip). Initially i set up wifi using HDMI connect to monitor. After 2months of work suddenly yesterday board is not connecting to my hotspot. I tried connecting to Monitor using HDMI to debug. But HDMI input is not working means when i connect to monitor and the monitor keep displays no input.
I can see LED1 glows for 500ms and LED2 blinks initially faster and then stops blinking after some time.
