[U-Boot-Users] Kernel does not boot

[Andy Chuo]

Hi all,

I'm having difficulties booting my kernel. I've checked the followings:

1.           CONFIG_CMDLINE_TAG, CONFIG_SETUP_MEMORY_TAGS and
CONFIG_INITRD_TAG all enabled. (#define as 1 in my include/configs/myboard.h
file)

2.           the machines descriptor in my board specific file under
linux/arch/arm/myboard.c as follows:

MACHINE_START(LP2A, "SOCLE-LP2A")

        MAINTAINER("Socle Ltd/DE1")

        BOOT_MEM(0x40000000, 0x1e800000,0x9e800000)

        BOOT_PARAMS(0x40000100)

        FIXUP(fixup_lp2a)

        MAPIO(lp2a_map_io)

        INITIRQ(lp2a_init_irq)

MACHINE_END

 

Few notes:

*            Kernel version is 2.4.21.rmk2 and was obtained from
www.kernel.org <http://www.kernel.org/> , cross compiler tool was from
www.gnuarm.com <http://www.gnuarm.com/>  - version 3.4.3.

*            It seems that misc.c does the decompression of the kernel
again, when kernel is already decompressed by u-boot to the load address
0x40008000.

*            Do I have to modify head.S at all?

 

I am pretty sure that I've done pretty much everything u-boot needs to boot
my kernel but it just won't do it (attached below is the log of the output
from the board). Can anyone help please? Thanks in advance!

 

Andy
