Ubuntu updating flash

30-Sep-2016 15:04

The Android flashing method is slightly different between RK3188 and RK3288, because most Rockchip RK3288 devices make use of e MMC flash, while older Rockchip RK3188 products feature NAND flash, and it appears Rockchip RK3xxx boot priorities (in the Boot ROM stored in the So C itself) are as follows: e MMC, SD card, and NAND flash.All that means is that an updated version of the bootloader is needed which looks for a bootable SD card, and although very unlikely, your device could end up being bricked during this procedure.That’s it now, you can just insert the SD card into your device to boot Android.For a quick try, you could download one of Ubuntu 12.04 or Ubuntu 14.04 SD card images, uncompress it, and flash it to a SD card with dd (Linux) or Win32Disk Imager (Windows).

Then may want to make sure your device is using RK3288Loader_uboot_V2.17.02bootloader (or latter).

You can do so by loading the firmware file (currently installed in your device) in Android Tool, flashing the firmware with upgrade_tool, running ‘cat /proc/cmdline’ in a terminal, or simply trying a bootable SD card with the method below.
