Easy Way to Edit script.bin in NAND Android Image?

[George Ioakimedes]

I'm trying to do some testing and looking for an easy way to test different configurations out quickly and easily. I can do this easily when I create a Linux install on the SD Card but that takes a long time to boot and is slow.

How can I access the script.bin file so I can download it on my development machine, use bin2fex, edit the file, then fex2bin, and finally transfer it back into the NAND?

George, I think the best way for fast testing is to use NFS rather than flash the NAND or write to SD each time.

There was a thread on that already.

To access the script.bin on the NAND, you need to mount the boot partition on the NAND, copy the file elsewhere ( or edit / decompile in situ)., then put back on the NAND.

Hi George,

I use this script update sys_config file only. Maybe It can help you.

sys_config()
{
printf "update sys_config ....\n"
PACK_DIR=${CUR_DIR}/lichee/tools/pack
cd $PACK_DIR/out/

cd $PACK_DIR/chips/sun4i/configs/crane/${1}
$PACK_DIR/pctools/linux/mod_update/script sys_config.fex
$PACK_DIR/pctools/linux/mod_update/script sys_config1.fex

#ls
#adb shell mount -o remount,rw /system
#adb shell mount -o remount,rw /

adb shell mkdir /mnt/sdcard/kernel
adb shell mount -t vfat /dev/block/nanda /mnt/sdcard/kernel
adb push sys_config.bin /mnt/sdcard/kernel/script0.bin
adb push sys_config1.bin /mnt/sdcard/kernel/script.bin

adb shell sync
#read -p "wait reboot..."

adb shell reboot
cd $CUR_DIR
}

Hi Kasper:

Do you run this in a shell on the Cubie (or SSH into the Cubie)? Do you need the Android SDK to run this?

[vasu devan]

  $adb shell

   mkdir /mnt/tmp

   mount -t vfat /dev/block/nanda /mnt/tmp

   exit

   $adb pull /mnt/tmp/script.bin

  

convert script.bin to script.fex with the help of windows program "fexc.7Z" ( If u need i will send it to ur email id)

   

 

In Windows cmd prompt:

   copy script.bin script0.bin

   $adb push script.bin /mnt/tmp

   $adb push script0.bin /mnt/tmp

   

   $adb shell

    busybox umount /mnt/tmp

    exit

Adb is an SDK command on Linux and windows. This code would need to be run on Linux.
