[U-Boot-Users] Linux Kernel Hangs..

[sudhakar rajashekhara]

Hi All,

I am trying to bring up Linux on EST8260 board. U-boot
has come up and I was able to run some example program
that comes along with U-boot. But when I am trying to
boot linux I am getting the following messages. (Debug
flag has been enabled).

I was going through the mailing list and I found that
many have faced similar problem. I am using Linux
2.4.22. I tried almost all the options like changing
the baudrate, setting and unsetting the clocks_in_mhz
variable, etc. The bd_info structure definition is
same both in Linux kernel tree and U-boot source. The
variables CFG_IMMR and IMAP_ADDR are also similar. I
even tried with a ramdisk image, then also the kernel
hangs at the same place. Is incorrect SDRAM
initialization a cause for this problem? Any sort of
help in this regard will be hugely appreciated.

thanks in advance...
regards,
Sudhakar.
