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.
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
Find out the strings as reported under settings.
In android, under Settings->About Tablet, you will find:
- Model Number: DEVICE
- Build Number: SOC_BOARD_DEVICE_*.*
U-boot-sunxi and linux-sunxi are supported.
- 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.
For building mainline u-boot, use the jesurun_q5_defconfig target.
Use the sun4i-a10-jesurun-q5.dts device-tree file for the mainline kernel.
NOTE: submitting patch is WIP (2015-02-26)
Tips, Tricks, Caveats
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
- Manually set video mode and disable hot-plug detection
sunxi# setenv video-mode sunxi:1280x720-24@60,hpd=0
- Make env variable persistent:
Verify: Check video-mode env variable:
sunxi# printenv video-mode video-mode=sunxi:1280x720-24@60,hpd=0
Adding a serial port (voids warranty)
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.
