imx6 LTIB error when generating rootfs.ext2.gz

[Tarek]

Hi ,

I'm using BSP 4.0.0 to build rootfs for imx6q. I have enabled the option to build rootfs.ext2:

I'm getting the following error:

Filesystem stats, including padding:

    Total size            = 752424k

    Total number of files = 7864

Your ramdisk exceeds the old default size of 4096k, you may need to

set the command line argument for ramdisk_size in your bootloader

allowing 10% free this gives 827666k .  For instance, for u-boot:

setenv bootargs root=/dev/ram rw ramdisk_size=827666

creating an ext2 compressed filesystem image: rootfs.ext2.gz

Ok I am getting the same error as above using L3.0.35_4.0.0_130424_source.tar.gz Linux BSP for imx6Q on SabreSD platform.  The rootfs built fine with all the default options initially and ran fine on my system.  Then I tinkered with some kernel settings to enable support for USB Modem.  After that ltib tried to rebuild the rootfs.ext2.gz and I got this error:

Please advise.

It looks like ltib/bin/Ltibutils.pm is not calculating the rootfs size correctly!

I changed this line:

genext2fs -U -b $blocks -i $inodes -D $dev_tab -d $stage $tdir/rootfs.ext2

To

genext2fs -U -b $fs_size_p10 -i $inodes -D $dev_tab -d $stage $tdir/rootfs.ext2

It's not the best fix but this works for now.

Thanks Tarek.

I didn't try out your solution because I did a clean re-build and the issue seems to have disappeared.
