Linux release ER 6 – 2012.08 Beta for i.MX6

Note: This image has been taken off-line because it’s been superseded.

Please use this tar-ball instead.

Original post

Following up on our previous posts covering our first impressions and our kernel patches, we’ve just uploaded a filesystem image with the ER6 – 2012.08 release from Freescale’s i.MX6.

You can download it from here:

The changes made to the Freescale image are all relatively minor but still worth mentioning:
  • We installed our kernel and modules, and
  • We added a boot script as discussed in this post., and
  • We edited /etc/profile to set LD_LIBRARY_PATH as discussed in this comment, and
  • We added firmware for the wl1271 WiFi module into /lib/firmware to allow use of Wi-Fi on the Nitrogen6X, and
  • We configured networking for eth0 using DHCP in /etc/rc.d/rc.conf, and
  • We removed fslgnome from cfg_services_r in /etc/rc.d/rc.conf/etc/rc.d/init.d/fslgnome doesn’t handle the stop command, the reboot process is held up otherwise, and
  • We added a password for the root user (“Boundary”) so you can log in over SSH.

To use this release, you can create a single-partition SD card using the ext3 filesystem and extract it there:
~/$ sudo tar --strip-components=1 -C /media/boot -zxvf ER6-1208-Beta.tar.gz

The boot script in this image expects to have two things in the bootargs environment variable:
  • console – normally console=ttymxc1,115200 to output kernel messages to the serial port.
  • video – See this post for details.
Here’s how I tested against HDMI:
U-Boot> set bootargs console=ttymxc1,115200
U-Boot> set bootargs $bootargs video=mxcfb0:dev=hdmi,1920x1080@60,if=RGB24
U-Boot> saveenv && reset
Check out the comments in our earlier post for some of the things supported in this release.

    I am unable to login after booting the filesystem image given above. Is ‘boundary’ the right password ?

    Booting the Filesystem works, but i recieve an error concerning the output screen:

    Error opening framebuffer /dev/fb0: No such file or directory
    Fatal server error:

    freescale login: matchbox-desktop: unable to open display !

    Hi, I am unable to use the (mfw_v4lsrc) camera with gst-launch to perform any
    type of operation?
    It gives me an the following error:

    ERROR: Pipeline doesn’t want to pause

      Hi Tom,

      Is this using the Timesys image, LTIB, or Ubuntu (or other)? I seem to recall that one of them requires that you manually modprobe mxc_v4l2_capture before the camera device is available.
