I build my own updater for imx28 based on Linux version 2.6.35.3 and always cannot download successfully.

By the way, the rootfs.tar.bz2, linux.sb, and ucl.xml I used is released by freescale.

Is there anyone here can give me some suggestion?

Below is the debug message out put from console when download fail.

Hi,

I never have this kind of problem.

I use ubuntu-10.04 to build the kernel. Config the packages to Minimum bootable root filesystem and use mfgtools to update.

 

You can change the the file in "rootfs/etc/rc.d/init.d/rc.conf" to let your  system run udev script(

http://ltib.org/documentation-LtibFaq  search "How to add a daemon to init" ). But I am not sure this will help.

 

 

Best Regards

Hi,

first thanks for your reply. I have already set LTIB options how you explained however I'll try again to install the BSP in new directory and configure LTIB. 

Now, I try to understand because at the boot of the kernel my system don't load udev script, that create shm directory ecc..(see below)

init started: BusyBox v1.15.0 ()

starting pid 1112, tty '': '/etc/rc.d/rcS'
Mounting /proc and /sys 
Setting the hostname to freescale
Mounting filesystems
mount: mounting shm on /dev/shm failed: No such file or directory

instead the linux kernel loaded in the sd card that freescale provide with i.MX28 EVK board execute udev script that create shm directory and start hotplug events (see below):

init started: BusyBox v1.15.0 ()

starting pid 1063, tty '': '/etc/rc.d/rcS'
Mounting /proc and /sys 
Starting the hotplug events dispatcher udevd
Synthesizing initial hotplug events
Setting the hostname to freescale
Mounting filesystems

Why my kernel don't execute udev script?

Have you any idea?

Thanks!

Here are the steps from Freescale Support to build the updater_ivt.sb.

1. install the BSP to a new directory 2. Change to the new directory and type this command to configure the build profile "./ltib -m selectype" Choose "imx_28" as platform type and "mfg firmware profile" as packages profile 3. Type "./ltib" to build updater.sb and updater_ivb.sb 4. Test the updater_ivb.sb using the default MX28 linux "SD(without uboot)" profile.

Step 1 is important to eliminate any dependence issues from existing object files.
