[U-Boot] booting the kernel

[Mathieu Dube]

Hi,
    Im trying to boot the linux kernel with uboot and it just hangs so I
tried the instructions in the Linux PostMortem FAQ entry.

I'd like to know if I could be doing something obviously wrong here:

the kernel I use is for freescale imx31_litekit. I've booted it using the
logicpd loader so I know it works.

I use the arch/arm/boot/Image with mkimage like this:

mkimage -A arm -O linux -T kernel -C none -a 86000000 -e 86000000 -d Image
image.bin

are the load address and entry point ok? if not how can I determine which
value they should have?

I tftp it to 0x81000000 like this:

tftp 0x81000000 /tftpboot/image.bin

that works fine

then I bootm

it loads the kernel and ends up printing:

Starting kernel ...

and hangs there, if I use my jtag I can see that the core is running ie: it
doesnt crash. Btw I've also tried with the jtag attached so thats not the
problem.

__log_buf in my System.map is at c035c168
and CONFIG_KERNEL_START is c0000000

so am I right to do

md 8635c168 ?

there doesnt seem to be anything interesting around this address...

what else could I try to figure out why the kernel isnt booting?

thanks a lot.
-M
