Rikomagic mk802

This is the most popular HDMI stick out there. While the original idea came from the FXI Cotton Candy, the MK802 really opened up the world of HDMI sticks.

Many devices are currently named MK802 as a result. Some use the same case, but have different innards (MK802+ and Semitime G2). The MK802II is a complete redesign, but uses an A10 as well. The MK802III and MK802IV are not allwinner based, and use a rockchip SoC instead.

Rumour has it that many clones were made, so who knows, if we get enough devices documented in our wiki, we might see some severe motherboard differences.

In android, under Settings->About Tablet, you will find:


 * Model Number: AK-MINI-PC-001
 * Build Number: crane_risctek-eng 4.0.3 IML74K 20120608 test-keys

Current status
Supported.

Manual build specifics

 * For building u-boot, use the "mk802" target.
 * The .fex file can be found in sunxi-boards as mk802.fex

Everything else is the same as the manual build howto.

= Tips, Tricks, Caveats =

FEL mode
The FEL button can be found by placing a pin into the hole in the bottom left corner on the top cover of the device. Pressing when powering up triggers FEL mode.

ADB
The device is factory rooted but so far ADB over USB hasn't been possible. To use ADB install a SSH Server like SSHDroid and start up the service. With the information provided by the Android App you can remotely log into the device(the login prompt displays the password. Type "adb shell" to enter ADB mode.

Device disassembly
The three piece case is clicked together. Do not try to get the semi-transparent bit around the USB Host connector off, as it is clipped into the top and you could damage the clip. Just gently push your plastic tool between the bottom and the top, and push the top part of the shell outwards. You will soon hear the clips release.

Locating the UART
The TX and RX pins for UART 0 are next to the SoC. A good place to solder the GND connection is on the ground plane that runs along the side of the board. More information is available at our UART howto.
