I'm trying to generate a bootable SD card for the Texas instruments am335x starter kit. The am335x is a Cortex-A8 (ARM).

  • bootloader is working: uboot, directly from Texas instruments
  • kernel is working: 3.2.0, directly from Texas instruments
  • rootfs is not working: ubuntu-core-12.04.2-core-armhf.tar.gz

I'm following these steps:

  • formatting the SD card with 2 partitions, one fat16 (boot) and one ext3 (rootfs)
  • placing the bootloader + kernel + MLO + uEnv.txt in the boot partition

    till here everything is ok with other rootfs, the next steps are for ubuntu-core

  • untar the ubuntu-core tarball in the rootfs partition

  • updating fstab with:

    /dev/mmcblk0p2   /           auto   errors=remount-ro   0   1
    /dev/mmcblk0p1   /boot/uboot auto   defaults            0   0
  • follow the steps in this tutorial for serial.conf http://www.omappedia.com/wiki/OMAP_Ubuntu_Core#Chroot.27ing_into_the_Ubuntu_Core_Filesystem

  • boot the SD card

The last lines of my log are:

    [    5.041076] kjournald starting.  Commit interval 5 seconds
    [    5.724517] EXT3-fs (mmcblk0p2): using internal journal

    [    6.035400] init: Failed to spawn hostname main process: unable to execute: No such file or directory

Anyone has an hint or an idea?
