Entwicklungsumgebung und Probleme Imagebau

[Audioniek]

@spartak73: I use this modified flash_part_w_fw.sh file to create root.img:

#!/bin/bash
#Version for Fortis HS-7810A with loader 6.26 (boot from USB, not flash)
if [ `id -u` != 0 ]; then
    echo "You are not running this script as root. Try it again as root or with su/sudo command."
    echo "Bye Bye..."
    exit
fi

CURDIR=$1
TUFSBOXDIR=$2
OUTDIR=$3
TMPKERNELDIR=$4
TMPROOTDIR=$5

echo "CURDIR       = $CURDIR"
echo "TUFSBOXDIR   = $TUFSBOXDIR"
echo "OUTDIR       = $OUTDIR"
echo "TMPKERNELDIR = $TMPKERNELDIR"
echo "TMPROOTDIR   = $TMPROOTDIR"

MKFSEXT3=mke2fs

OUTFILE=root.img

if [ ! -e $OUTDIR ]; then
  mkdir $OUTDIR
fi

if [ -e $OUTFILE ]; then
  rm -f $OUTFILE
fi

if [ ! -e /mnt/temp ]; then
  sudo mkdir /mnt/temp
fi

echo "-----------------------------------------------------------------------------"
# --- KERNEL ---
# Size is 8MB max.
echo ""
echo "Copying kernel file..."
cp -f $TMPKERNELDIR/uImage $OUTDIR/uImage
#padding of kernel uImage is not needed
#$PAD 0x800000 $CURDIR/uImage $CURDIR/mtd_kernel.pad.bin

echo "-----------------------------------------------------------------------------"
# --- ROOT ---
# Size is 256MB
echo ""
echo "Creating root image file..."
#Create an empty file of 256M size
echo "dd if=/dev/zero of=$CURDIR/ext3.img bs=512 count=512000"
dd if=/dev/zero of=$CURDIR/ext3.img bs=512 count=512000
#Attach it to a loop device
echo "sudo losetup /dev/loop0 $CURDIR/ext3.img"
sudo losetup /dev/loop0 $CURDIR/ext3.img
#Create an ext3 file system in the empty file
echo "sudo $MKFSEXT3 -t ext3 -L root.img /dev/loop0"
sudo $MKFSEXT3 -t ext3 -L root.img /dev/loop0
#Detach the loop device
echo "sudo losetup -d /dev/loop0"
sudo losetup -d /dev/loop0
#Mount $CURDIR/ext3.img on a temporary mount
echo "sudo mount -t ext3 $CURDIR/ext3.img /mnt/temp"
sudo mount -t ext3 $CURDIR/ext3.img /mnt/temp
#Copy the root file system to the mount
echo "cp -r -f -p $TMPROOTDIR/* /mnt/temp"
cp -r -f -p $TMPROOTDIR/* /mnt/temp
#Create a swap directory
echo "Create a swap directory if not already done"
if [ ! -e /mnt/temp/swap ]; then
  sudo mkdir /mnt/temp/swap
fi
#Unmount $CURDIR/ext3.img on the temporary mount
echo "sudo umount /mnt/temp"
sudo umount /mnt/temp
echo "-----------------------------------------------------------------------------"
echo ""
echo "Preparation of root image file completed,"
echo "checking file sizes..."
SIZE=`stat $TMPKERNELDIR/uImage -t --format %s`
SIZE=`printf "0x%x" $SIZE`
if [[ $SIZE > "0x800000" ]]; then
  echo "KERNEL TOO BIG. $SIZE instead of 0x800000" > /dev/stderr
else
  echo "Kernel (uImage) is $SIZE bytes... OK"
fi

SIZE=`stat ext3.img -t --format %s`
SIZE=`printf "0x%x" $SIZE`
if [[ $SIZE > "0xfffffff" ]]; then
  echo "ROOT TOO BIG. $SIZE instead of 0x10000000" > /dev/stderr
else
  echo "Root image file is $SIZE bytes... OK"
fi

mv $CURDIR/ext3.img $OUTDIR/$OUTFILE
echo "-----------------------------------------------------------------------------"
echo ""
echo "Creating zip-file..."
cd $OUTDIR;zip $OUTFILE.zip $OUTFILE uImage

The file replaces the file with the same name in the ../flash/hs7810a/scripts folder and is called from the flash shell script.

After running this, you have the correct root.img, but uImage still has got a problem I have not solved yet and is addressed in this thread. I suspect it has something to do with a missing or empty initramfs.
