If someone want to add gpio pin or uart without compile the source code.The sunxi-tools can help you.

[edit] Before you start

Download and install the software needed

sudo apt-get install build-essential make gcc g++ git-core

[edit] Android

At first You may need fex2bin and bin2fex:

git clone git://github.com/linux-sunxi/sunxi-tools.git
cd sunxi-tools
make
With the using of ls, you can find the fex2bin and bin2fex.

Second copy the script.bin from Android OS:

adb shell
mkdir /mnt/tmp
mount -t vfat /dev/block/nanda /mnt/tmp
exit
adb pull /mnt/tmp/script.bin 

Note : Attention it's different from Linux.

Then convert the script.bin to script.fex:

chmod 777 script.bin
./bin2fex script.bin > ./script.fex
gedit script.fex

Now, you can edit the script.fex. Don't forget saving the file when you leave it.

Finally,convert the script.fex to script.bin and push it back to the MarsBoard

./fex2bin script.fex > ./script.bin
adb push script.bin /mnt/tmp
adb shell
umount /mnt/tmp
reboot

It will restart the MarsBoard. The new script.bin will come into effect.


[edit] Linux

You can edit the script.bin directly Firstly, you must connect network and install compilation Tools:

git clone git://github.com/linux-sunxi/sunxi-tools.git
cd sunxi-tools
make

With the using of ls, you can find the files: fex2bin and bin2fex.

Copy the script.bin.(boot from sdcard):

mkdir /mnt/mmcp1
mount /dev/mmcblk0p1 /mnt/mmcp1  (the script.bin is in /dev/nanda if you boot from nand)
cp /mnt/mmcp1/script.bin ./

Copy the script.bin.(boot from nand):

mkdir /mnt/mmcp1
mount /dev/nanda /mnt/mmcp1  (the script.bin is in /dev/mmcblk0p1 if you boot from sdcard)
cp /mnt/mmcp1/script.bin ./

Convert the script.bin to script.fex:

chmod 777 script.bin
./bin2fex script.bin > ./script.fex
vi script.fex

Now, you can edit the script.fex.Don't forget saving the file when you leave it.

Convert the script.fex to script.bin and push it back.

./fex2bin script.fex > ./script.bin
cp ./script.bin /mnt/mmcp1/
umount /mnt/mmcp1
reboot

It will restart the MarsBoard. The new script.bin will come into effect.

Note:When the script.bin is invalid.You must enter the u-boot command line and input

setenv boot_normal fatload nand 0 43000000 script.bin\;boota 40007800
saveenv
reset
