Instructions to install GK802 dCore to sdcard, first boot and inital setup.

--------------------------------------------------------------------------------
Step 1. Go to  http://tinycorelinux.net/5.x/armv7/GK802 and download mksdcard.tgz 

This unpacks into an sdcard directory. Therein I have mkSDcard.sh
I use Tiny Core, so you will need to have util-linux.tcz loaded.
Use the script specifying your umounted sdcard,, e.g.,

./mkSDcard sdd

Caution: your sd card will be wiped clean and reformatted.

--------------------------------------------------------------------------------
Step 2. Use gparted, fdisk, or sfdisk to add a swap and regular linux partitions to fill up the remaining sd card. Swap is not absolutely necessary, but may be helpful for some users.  Be sure to mkswap and format respectively.
Note: That uboot uses the first part of disk so be extremely careful when selecting starting cylinder numbers. 

You may wish to use a pendrive for your collection of extensions and backup. If you do so you will need to use a waitusb option. Even some sdcards may need a waitusb option.

NOTE: Updating boot codes will be covered after successful boot on GK802.
--------------------------------------------------------------------------------
Step 3. On your GK802 device, insert sd card into internal slot and apply power. Core boots very quickly to the $ prompt.
NOTE: You must use the internal sdcard slot. Requires opening the GK802 to access.

--------------------------------------------------------------------------------
Step 4. You need to setup your tce directory to store downloaded and imported extensions. 
At the $ prompt type:

tce-setdrive

You should then select by number the partiton that you setup to hold extensions 
from Step 2. If you do not see the expected partition then you must update your boot codes.
See: README-bootcodes.txt

Then add waitusb and LABEL options and reboot to try again. 

--------------------------------------------------------------------------------
Step 5. Check that you network is up and that you have an IP number, type ifconfig to verify.  If you only have wireless access then see the README-wifi.txt

NOTE: Existing wifi.sce, wireless-tools.sce, and wpasupplicant.sce should work fine.
NOTE: This cut has a boat load of modules, I have not yet begun to cut. You will not need 8192cu.sce as such module is contained in the base.
--------------------------------------------------------------------------------
Step 6. From CLI, the $ prompt, to backup simply type

backup

-------------------------------------------------------------------------------
Step 7. To shutdown from CLI type

sudo poweroff
