I have changed mk3PartSDCard.sh in the sdk.
#! /bin/sh
# mk3PartSDCard.sh v0.3
# Licensed under terms of GPLv2
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`
sfdisk -D -H 255 -S 63 -C $CYLINDERS $DRIVE << EOF
,10,0x0C,*
11,115,,-
127,,,-
EOF
mkfs.vfat -F 32 -n "boot" ${DRIVE}1
umount ${DRIVE}1
mkfs.ext3 -L "rootfs" ${DRIVE}2
umount ${DRIVE}2
mkfs.ext3 -L "START_HERE" ${DRIVE}3
then ,sd crad boot partition has been changed from 74mb to 82mb.
when I used the sd card to boot my AM335x EVM I got 'ccccccccc' from the terminal.
Is this means I can,t changed the size of sd card partition?
If the size can be changed how to do it.
