boot failure on lite5200b board

[#LI JIANGGAN#]

Thank you José María and Andrey for your advices, however the problem remains. I've tried setting the console (though I remember that our previous lite5200 board was working fine on kernel 2.4 without setting the console); meantime, I've set the booting image to 0x500000; I have also tried using the kernel image come together with the BSP, it's always the same error.

Sylvain, I've actually using your kernel source, the compiled image is around 700k (compared to the 1.4M image from the BSP), but it doesn't solve the problem. So I presume that the problem is lying somewhere else.

A SNAPSHOT OF THE BOOTING MESSAGES:

I am wondering whether it's a kernel problem or more likely to be a problem lying with the U-boot. It seems to hang when executing setup_arch() function, or maybe there is sth else behind the wall?

In addition to what has already been said (use a higher address for the
image and don't forget console=ttyPSC0 in kernel command line), make
sure you use the kernel from my git tree, it contains a few patches from
John Rigby to add support for the lite5200b.

Please report if it works, I've not been able to test those myself since
i'm still on lite5200.
