[U-Boot-Users] do_bootm_linux problem

[Oliver Fuchs]

Hi all,

I try port U-Boot 1.1.1 to a board with MPC8280.
It seems to work but booting the Linux kernel failed without any print after
"Uncompressing Kernel Image ... OK"
I have already checked the cases mentioned in DULG 13.2.5.
I found that within the function do_bootm_linux the pointer "kernel" is 0.
Within the global structure header I found the following:
  header = (
    ih_magic = 0x27051956,
    ih_hcrc = 0x0,
    ih_time = 0x40EBFB9A,
    ih_size = 0x000863D7,
    ih_load = 0x0,
    ih_ep = 0x0,
    ih_dcrc = 0xC3C4EF02,
    ih_os = 0x5,
    ih_arch = 0x7,
    ih_type = 0x2,
    ih_comp = 0x1,
    ih_name = 'L', 'i', 'n', 'u', 'x', '-', '2', '.', '4', '.', '2', '4', '-', 'p', 'r', 'e', '2', '.')

The kernel is the one shipped with ELDK 3.0 made by make uImage.

What could be wrong?

Thanks in advance,
Oliver

I recommend to use the top-of-trunk in the CVS for all ongoing work.

This does not matter here at all.

The adaption of the Linux kernel for your board?

I think you have to make sure that you serial port is working well for your 
kernel.
pls check the command line in your linux config. Pay attention to choose 
the ttyS0 or ttyS1 for your board, and set the baurdrate  right both in the 
command line and the terminal.
