i have make a bootable sd card but when i put sd card in beagleboard sd card slot the screen is looking white .its not showing any thing .
i press reset button while holding user button but it still shows nothing .
i have make sd card bootable in the following ways i have make two files setup_sd and load_sd.
(setup_sd) Inside setup_sd:
#!/bin/sh
As per instructions:
http://elinux.org/BeagleBoardBeginners
if [ $# -lt 1 ]; then
echo “example usage: $0 /dev/sdb”
exit 1
fi
DRIVE=$1
dd if=/dev/zero of=$DRIVE bs=1024 count=1024
SIZE=fdisk -l $DRIVE | grep Disk | awk '{print $5}'
echo DISK SIZE - $SIZE bytes
CYLINDERS=echo $SIZE/255/63/512 | bc
echo CYLINDERS - $CYLINDERS
{
echo ,9,0x0C,*
echo ,-
} | sfdisk -D -H 255 -S 63 -C $CYLINDERS $DRIVE
mkfs.vfat -F 32 -n “boot” ${DRIVE}1
mke2fs -j -L “rootfs” ${DRIVE}2
now inside load_sd:
#!/bin/sh
As per instructions:
http://elinux.org/BeagleBoardBeginners
if [ $# -lt 1 ]; then
echo “example usage: $0 /dev/sdb”
exit 1
fi
DISK=$1
if [ -e Angstrom-Beagleboard* -a -e MLO -a -e u-boot* -a -e uImage* -a -e modules* ]; then
echo "All files found okay… "
echo “Mounting ${DISK}1 and ${DISK}2”
mkdir /mnt/sd1; mount ${DISK}1 /mnt/sd1
mkdir /mnt/sd2; mount ${DISK}2 /mnt/sd2
sleep 2
echo “Copying to ${DISK}1 and ${DISK}2”
cp MLO u-boot.bin /mnt/sd1
cp uImage* /mnt/sd1/uImage
tar -xvf Angstrom-Beagleboard-demo-image*.tar.bz2 -C /mnt/sd2
tar -xvf modules-2.6.*.tgz -C /mnt/sd2
echo “Unmounting ${DISK}1 and ${DISK}2”
umount ${DISK}1; umount ${DISK}2
rm -rf /mnt/sd1 /mnt/sd2
echo “Done”
else
echo “Files missing!”
echo “Downloading required files… this may take some time.”
sleep 2
