UpBoard not booting, no hdmi, no usb power supply after installation Ubilinux 4.0
after installation Ubilinux 4.0 on brand new UpBoard (32gb, intel atom) I was asked to restart board. After this upboard can't run, nothing happens. There is no HDMI signal(monitor goes to standby mode after pluggin to upboard), USB mouse connected to the usb does not light up. Only power LED lights up in blue. I tried to disconnect RTC battery for long time and it doesn't work. Any suggestions? I could break UpBoard through the Ubilinux installation?
Thanks for any help.
