[U-Boot-Users] U-boot hang after uncompressing kernel.

[Ashay Jaiswal]

Hello,
    I am a new U-boot user using it for SH target.

I am trying to boot linux-2.6.17 on the target board using uboot
bootloader but it hangs after following message.


   Booting image at 8c400000 ...
   Image Name:   Linux-2.6.17-sh
   Image Type:   SuperH Linux Kernel Image (gzip compressed)
   Data Size:    1191073 Bytes =  1.1 MB
   Load Address: 8c002000
   Entry Point:  8c002000
   Verifying Checksum ... OK
   Uncompressing Kernel Image ... OK

After the above message kernel hangs.


Thanks in advance.......

Best Regards

Maybe you have a wrong machine id, try to enable early debug option if 
is it possible.

[U-Boot-Users] U-boot hang after uncompressing kernel.

Hi Ashay

I face the same problem some times ago because of bad bootargs passed to
the kernel from u-boot.

If you manually start the kernel from u-boot command line then you
should not set bootargs env variable to empty string (with background
idea that Linux will use default bootagrs compiled with the source). In
that case the kernel try to boot with empty bootargs and then hangs.

If it is autostart process then you should check what bootargs are set
in the config file (in u-boot/include/configs/*.h, * stand for your
specific board).

You can found a lot of information in doc file u-boot/README and on the
u-boot documentation http://www.denx.de/wiki/DULG/Manual

Hello Ashay,

>     I am a new U-boot user using it for SH target.

What version of U-Boot are you using?
Which board and processor are you using?
If it is not the official U-Boot distribute by http://www.denx.de/,
where did you get it from?

Is it a kernel from http://www.kernel.org/?
If not, where did you get the kernel from?
Using which configuration options did you compile this kernel?

Best Regards,
Mark

Please always keep the U-Boot mailing list in copy so others might help
you as well and the whole group benefits. Please try to be as specific
as possible when describing your problem. No top posting and no full
quotes helps as well.

Answering the questions I sent you will be a good step in finding a
solution, too. I repeat my questions which have not been answered:

Which board and processor are you using? Many eval boards from Renesas
are named "Solution Engine". I have one named "Solution Engine
MS7720RP01" and it is for the SH7720 processor.

If it is not the official U-Boot distribute by http://www.denx.de/,
where did you get it from?

Do you have the source code of U-Boot and which target did you use to
compile it?

Is it an unmodified kernel from http://www.kernel.org/?

If not, where did you get the kernel from?

Using which configuration options did you compile this kernel?

Mark
