Hi, I want to run initramfs to update emmc if image available au usb storage device script as follow
///////////////////////////////Installer.sh///////////////////////////////////// #!/bin/sh emmc="/dev/mmcblk1" bootpart="p1" mpoint=""; usbdev="/dev/sda1" egiimage="/mnt/egi/sdcard.img.bz2" echo "egiimage=$egiimage" if ! [ -b "$usbdev" ] then echo "USB Block Device not found!! $usbdev" exit 3 else mount /dev/sda1 /mnt/egi/ if ! [ -e "$egiimage" ] then umount /mnt/egi echo "Egi Image not found!!" exit 3 fi fi if [ -b "$emmc" ] then echo "SD card detected!!" #dd if=$egiimage of=/dev/mmcblk1 mpoint="/dev/mmcblk1" else echo "SD card not detected!!" #dd if=$egiimage of=/dev/mmcblk0 mpoint="/dev/mmcblk0" fi # led blink logic bzcat $egiimage | dd of=$mpoint //////////////////////////////////////////////////////////////////////////// Above script tested and working fine when running from command line For root file system I refer https://embedjournal.com/custom-rfs-beaglebone-black/ whereas I used my busybox and cross compiler which is used to build kernel uImage. I created soft link init in / to /bin/busybox and added above script .Installer.sh to etc/inittab as: ---------------------------------------------------------------- null::sysinit:/bin/mount -a null::sysinit:/bin/hostname -F /etc/hostname null::respawn:/bin/cttyhack /bin/login root null::restart:/sbin/reboot null::wait:/root/Installer.sh ------------------------------------------------------------- When usb is not connected and power up board it will be hanged at: Freeing init memory: 8416K My expectation is call main rootfs from /dev/mmcblk0p2 but it hangs. Even if I comment Installer.sh from etc/inittab it keep hanging. I guess my procedure is wrong. please anyone suggest how to do it. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
