Hi,
I just received my "Rock Pi 4 Plus Model B Rockchip RK3399(OP1) Single Board Computer LPDDR4 4GB with WiFi 5 and Bluetooth 5.0 Support Twister OS " from Amazon.
After I connect HDMI to monitor and usb key board and mouse, I powered it up. But nothing boot up. Only power green LED is on. Twister OS suppose to be installed for this board. What else should I do to this board before I power it up? HELP !!!
Thanks,
Yili
