[Puneet B]

Hi i flashed the cubieboard image to sd card from this link.

https://docs.google.com/file/d/0B-bAEPML8fwlUFd5OHVOaFJIRmc/edit.

then in Volumn(bootlaoder)  folder of sdcard i got fallowing binaries.

1.boot.axf
2.boot_signature.axf 
3.drv_hdmi.drv 
4.font32.sft 
5.magic.bin 
6.prvt.axf   
7.script.bin
8.boot.ini 
9.drv_de.drv      
10.font24.sft  
11.linux       -> linux.bmp  linux.ini  u-boot.bin (sub contents). 
12.os_show   ->bat0.bmp   bat2.bmp  bat5.bmp  bat8.bmp     bempty.bmp    full.bmp    linux2.bmp   melis2.bmp   wince1.bmp
                  bat10.bmp  bat3.bmp  bat6.bmp  bat9.bmp     bootlogo.bmp  head.bmp    low_pwr.bmp  startup.bmp  wince2.bmp
                  bat1.bmp   bat4.bmp  bat7.bmp  battery.bmp  empty.bmp     linux1.bmp  melis1.bmp   tail.bmp

 
13.script0.bin 
14.sprite.axf


Out of these i know script.bin , and u-boot.bin (but i flashed to /dev/sdc ).

This is the allwinner 'battery charging app' that also chainloads u-boot
if need so.

the linux splash screen (android actually) an ini file to tell boot.axf
what and how to boot it (it being u-boot).
u-boot here is the lichee-u-boot, one that does NOT init dram, but DOES
support NAND

boot.axf image files (like empty battery, charging, some pics they
intended to use as boot selector that never happened.

backup copy of script.bin, in case 1 is broken it tries to read this one

you cannot flash that u-boot to a SD card, it works only on nand, and
you shouldn't mess with it.

YOu really don't know this yet? Have you ever looked at our wiki?

boot0 is allwinner's version of what we call u-boot-sunxi-spl. boot1 is
allwinners variant of what we call u-boot.bin boot0/1 is what we call
u-boot-sunxi-with-spl.bin which is inteded to be flashed to an mmc card,
starting at the 8k marker.
