Linux/TMS320DM8148: Linux Kernel - "uncompression error -- System halted"

Hi Ybrk,

Do you use DM814x EZSDK 5.05.02.00 or else?

Please provide the exact commands you are using to create your uImage.

Hi Pavel,

1. I'm using DVRRDK_04.01.00.02

2. The uImage is been created by DVRRDK's script using 'make dvr_rdk_linux' command
but I also tried with this:
mkimage -A arm -O linux -T kernel -C none -a 0x80008000 -e 0x80008000 -n "Linux-2.6.37+" -d Image.gz uImage
and
mkimage -A arm -O linux -T kernel -C none -a 0x80008000 -e 0x80008040 -n "Linux-2.6.37+" -d Image.gz uImage

3.I followed these threads without success.

4. NEW:
The uImage is uncompressed when I comment out the 'bl cache_on' at the kernel head.S file. but it takes lots of time.
when the uncompression done, there is a few lines printed out from the kernel but it also hangs. see below.

Please advice

Ybrk,

Please try to create your uImage following the below guidelines.

Hi Pavel,

I tried with this without success.
mkimage -A arm -O linux -T kernel -C none -a 0x90008000 -e 0x90008000 -n 'Linux-2.6.37' -d arch/arm/boot/zImage uImage

why do you think this is uImage problem ? I was able to boot this uImage on our evb.

Please advice.

This issue seems specific for RDK. Refer to the below e2e post:
