i.MX28evk sd boot faults

Hello everyone,

 

I'm trying to create a bootable SD card as descriped in the LTIB_for_i.MX28__a_step-by-step_guide .

 

I've tried the following steps with a fresh freescale-ltib-ubuntu vm-image.

 

* start the terminal in LTIB directory

* ./ltib

    Elapsed: 1 seconds

 

    Build Succeeded (ltib is preconfigured by freescale)

* mk_mx_28 /dev/sdb

    confirmed with yes and entered password for madfsl

    [...] Done! Plug the SD/MMC card into the i.MX board and power-on.

   

alright so far..

 

but if I boot the i.MX28 evk from this SD card I got errors.

Sometimes:

Uncompressing Linux...

 

invalid compressed format (err=2)

 

-- System halted

 

and sometimes

 

Uncompressing Linux...

 

incomplete literal tree

 

-- System halted

 

But if I rename the imx28_ivt_linux.sb to imx28_linux.sb and overwrite the file in the ~ltib/rootfs/boot folder and execute the mk_mx28_sd script again than the evk starts without any faults.

So I'll think there is something missing in the ltib configuration, but I have no idea what.
