Hi, I am trying to run Android SDK on ARM RealView board based virtual platform having Cortex-9 processor. The board has two nor flash (flash0 and flash1) of 64M each. Taken android-2.6.32 version kernel, I, configured, modify, built and booted it on the platform.
The flash has been partitioned (using MTD subsystem) like this: armflash.0 -> First 2M for android Kernel and next 2 MB for busybox based cramfs image armflash.1 -> Full 64 MB for android root (JFFS2) image Current situation is that I am able to boot android kernel and log it into cramfs image. Now after that I mount the android root on tmpfs using the following command mount -t jffs2 /dev/mtdblock2 /tmpfs/android The command executes successfully, but when I run "ls /tmpfs/android", system seems to go into infinite loop and the prompt never comes back. (Other Details) I prepared the android rootfs as follows : using cpio, I unzip the ramdisk.img image that comes with Android 2.1 platform. Downloaded pre-built system.tar.gz and data.tar.gz from http://benno.id.au/blog/2007/11/14/android-filesystems, untar them into the rootfs directory. and then running the command mkfs.jffs2 -n -s 128 -r _install -o root_jffs2.img where _install is my android rootfs directory and root_jffs2.img is the output image. The size of root_jffs2.img is around 48MB. Other observations are: =================== When I keep the the partition size of android rootfs on armflash.1 to be 32 MB the ls commands succeeds. But due to obvious reasons when I run "chroot /tmpfs/android /int", I got segmentation fault. I don't understand why the ls commands works (for the same image) when the partition size is equal to 32 MB but not when partition size is 64MB and what should I do to correctly mount the android rootfs. Any help in this regard will be highly appreciated.
