EM3288 Manual
EM3288 is a single board computer based on the Rockchip RK3288, Quad Core Cortex-A17 @1.8GHz. RK3288 is powerful on multithreaded computing operation, graphics processing and video decoding ability. RK3288 supports Mali-T760 MP4 Graphics Processing, openGL ES1.1/2.0/3.0, OpenVG1.1, OpenCL, Directx11, and can 4Kx2K achieve 4kx2k H.264 and 10 bits of H.265 video decoding, 500% performance boost over Mali-400. On display aspects, RK3288 supports up to 18Gbps Data transmission rate and 4Kx2K@60Hz Video resolution.
The HD+ High Resolution IPS multi-touch 10.1" display technology features a crisp, clean and sharp 1280x800 High Definition display that is visible from virtually any angle. As well as 7" multi-touch LCD can be supported by EM3288 now.
EM3288 also supports Miracast which can project the screen to TVs, projectors, and streaming media players that also support Miracast. User can use this to share what you’re doing on your device, present a slide show, or even play your favorite game on a larger screen.
The platform is implemented with a MINI3288 computer-on-module providing most of the functions and interfaces, and EM3288_C carrier board providing connectors and several additional functions. The rich feature set of EM3288 is customizable according to the price / performance needs of the target application. EM3288 contains expansion connectors which accommodate a wide range of standard peripheral devices.

Ubuntu
Replace the kernel source logo_linux_clut224.ppm file in the path: \kernel\drivers\video\logo\logo_linux_clut224.ppm
After change file user needs to rebuild the kernel. Change the *.png(1920x1080) picture to *.ppm file as follow:
Execute the command in ubuntu:
# sudo apt-get install netpbm (install tool)
# pngtopnm linux_logo.png > linux_logo.pnm
# pnmquant 224 linux_logo.pnm > linux_logo224.pnm
# pnmtoplainpnm linux_logo224.pnm > logo_linux_clut224.ppm
Android 9
Replace logo.bmp and logo_kernel.bmp in the source directory …/kernel, then recompile.
Yes.
The input current is 3A. Less 3A will cause the system restart. It is suggested to adopt the standard power adaptor (5V/3A).
No.
There are two kinds of signal - TTL and LVDS. They share one interface, you can only choose one to display. The VGA is RGB signal, only TTL can output RGB, so if you use LVDS, the VGA will not display.
The LVDS resolution is fixed can't be changed.
Change HDMI resolution:
cat /sys/class/display/HDMI/mode (view current resolution)
cat /sys/class/display/HDMI/modes (view support resolution)
echo 1920x1080p-60 > /sys/class/display/HDMI/mode (set resolution)
Download and install WNpctool_Setup_V1.1.2_1226.exe, then run it.
Please refer to the document for details How to Change EM3288 MAC Address.
upgrade_tool is a firmware upgrade tool for Linux. Flash image requires superuser privileges.
1. Download and execute upgrade_tool first.
2. Put the firmware files and upgrade_tool in the same directory.
3. Connect the USB OTG port from the board to your PC, press the recovery button from your board, and connect the power, wait a few seconds and release the button.
4. Use the commands to flash image.
Basic Commands
//List devices upgrade_tool ld //Download boot upgrade_tool db rkxxloader.bin //Flash the partition table upgrade_tool di -p parameter.txt //Flash single partition image upgrade_tool di -k kernel.img //Falsh multiple partition images upgrade_tool di -u uboot.img -b boot.img //Flash the partition image with no defined abbreviation, you need to specify the partition name. //Take the vendor partition as an example upgrade_tool di -vendor vendor.img //When ab partition are used, it also needs to be handled in undefined cases. //Take boot_a and boot_b as example upgrade_tool di -boot_a boot.img -boot_b boot.img //Flash loader and reset upgrade_tool ul rkxxloader.bin //Upgrade firmware and reset upgrade_tool uf update.img //Erase device upgrade_tool ef rkxxloader.bin
