evb-3288 board RK3288-based development board with 2 USB ports, HDMI, VGA, micro-SD card, audio, WiFi and Gigabit Ethernet. It also includes on-board 8G eMMC and 2GB of SDRAM. Expansion connector provide access to display pins, I2C, SPI, UART and GPIOs. This add some basic files required to allow the board to output serial messaged and can run command(mmc info etc). evb-rk3288 also supports booting from eMMC or SD card, the default is eMMC.
