Jesurun Q5

The Jesurun Q5 is a cheap A10 based media puck, with a distinctive case with the top and bottom panels consisting almost entirely of ventilation holes.

= Identification =

Apart from a Jesurun sticker, there are no external markings.

The PCB has the following silkscreened on it: AVM STV301 MB V1.1 2012.07.16

= Sunxi support =

Current status
U-boot-sunxi and linux-sunxi are supported.

Manual build

 * For building u-boot, use the jesurun_q5_defconfig target.
 * The .fex file can be found in sunxi-boards as sys_config/a10/jesurun-q5.fex

Everything else is the same as the manual build howto.

Mainline U-Boot
For building mainline u-boot, use the jesurun_q5_defconfig target.

Mainline kernel
Use the sun4i-a10-jesurun-q5.dts device-tree file for the mainline kernel.

= Tips, Tricks, Caveats =

FEL mode
There is a solder mask for a button on the board that might trigger FEL mode, but it is not populated.

Mainline U-Boot: HDMI hotplug detection does not work
Workaround: sunxi# setenv video-mode sunxi:1280x720-24@60,hpd=0 sunxi# saveenv
 * Manually set video mode and disable hot-plug detection
 * Make env variable persistent:

Verify: Check video-mode env variable: sunxi# printenv video-mode video-mode=sunxi:1280x720-24@60,hpd=0

Device disassembly
This casing is trivially disassembled by removing 4 Philips screws on the bottom.

Locating the UART
The UART pads are clearly marked on the top of the board. You can solder in a 2.54mm pitch header as shown in the picture, or you can solder on wires directly. For more information read our UART howto.
