Linux: Creating SquashFS for AM335x

Other Parts Discussed in Thread: TPS65217

Tool/software: Linux

Kindly share steps to create squashfs on Ubuntu 16.04 LTS filesystem using beagle bone board and bootup using Sd Card.

What should be the fstab contents for the same?

  • Hello Manali,

    You can create squashfs with mksquashfs command:

    cd <Processor SDK>/filesystem/
    mkdir rootfs
    sudo tar xvf tisdk-rootfs-image-am335x-evm.tar.xz -C rootfs/
    sudo mkdir -p rootfs/media/ram
    sudo mksquashfs rootfs/ filesystem.squashfs
    sudo dd if=filesystem.squashfs of=/dev/sdX2

    To create the squashfs image while building the OE SDK.

    You need to add this to build/conf/local.conf

    EXTRA_IMAGE_FEATURES += "read-only-rootfs"
    IMAGE_FSTYPE += "squashfs"

    And this to sources/meta-arago/meta-arago-distro/recipes-core/images/arago-base-tisdk-image.bb

    do_install_append ( {
    mkdir -p ${D}/media/ram
    }
    FILES_${PN} += " \
    /media/ram \
    "

    Note: You know that the U-Boot has no SquashFS support and you need to load the device tree and the kernel from the SD card's fist partition right?

    Best regards,
    Kemal

  • Hi Kemal,

    Thank you for sharing details!

    I have Ubuntu 16.04 LTS filesystem running on beagle bone black. Can I use the above steps on the LTS filesystem?

    I am not using ti-sdk for building rootfs so can I build squashfs on beagle bone itself using above steps?
  • This forum supports only the TI SDK. Please, ask in BBB community and Ubuntu 16.04 LTS forums about how they create their squashfs filesystem.
  • Thank you Kemal!

    I have downloaded TI SDK linux-am335x-evm-04.01.00.06 and created squashfs filesystem as you mentioned in above chain.

    I copied squashfs to "/dev/sdd2" i.e second partition of sd card and first partition has u-boot.img, kernel zimage and MLO. Both partitions are of VFAT type and I created 3rd partition of Ext4 type.

    I am trying to bootup with below bootargs:

    setenv bootargs console=tty0 console=${console} ${optargs} ${cape_disable} ${cape_enable} root=/dev/mmcblk0p2 rootfstype=squashfs rootwait ${cmdline}

    I am not able to boot-up with squash.

    Kindly share your views on the same.

  • Can you attach the log?
  • Hi Kemal,

    I am using prbuilt zImage and created filesystem.squash  fom ti-sdk and trying bootup

  • Do not just copy the filesystem.squashfs to SD card, it is an image. Use dd command to reflect and write its raw content directly over the SD card's partition.
    sudo dd if=filesystem.squashfs of=/dev/sdd2

  • when I used dd command I'm getting Input/Output error. Filesystem.squashfs is not getting copied completely.

    When try to see content of /dev/sdd2 where squash is copied it gives Input/Output Error.

    While executing dd it show below message as

    909872+0 records in

    909872+0 records out

    Any Ideas on this?

    Thanks,

    Mrudula

  • Format the partition before flashing it with dd command, and make sure that this image can fit into this SD card.
    sudo dd if=/dev/zero of=/dev/sdd2
