Hi Wolfgang
Thanks for quick response.
I am kind of helpless regarding the kernel version, as our customer is
using it and I need to replicate their environment. I just tried 2.6.28
with katmai_defconfig file and still face the same problem.
The config file that I sent before is provided by the customer. It is a
working configuration for them.
The exact board that I have is Katmai.
I verified that I am using serial port 0. I tried to set bootargs to
just console=ttyS0,115200 and I don't see the kernel booting. Everything
in env variables seems ok to me unless something trivial is missing my
eyes.
My sequence for boot is
=>tftp 0x1000000 uImage-ppc
=> run flash_nfs (I have done this manually also)
my printenv output is as follows.
Thanks for your help
Shubhada

2.6.23.10 is very old. Please use current code. 2.6.23 was long before
the switch to arch/powerpc, so all the efforts you are spnding now on
this old stuff are really wasted.
Use at least 2.6.28 or later.

Why don't you start with a good, known to work kernel config file
like 44x/katmai_defconfig ?
For example, you mention a 440SPe processor above, but your config
file seems to be derived from a Luan board, which is 440SP (not SPe)
so there is not much surprise if it doesn't work.

In the first place, please use current code.
Second - which exact board is this? Katmai?
> => run flash_nfs
What exactly are your environment settings? Which exact value of
"bootargs" do you pass to Linux? Does it include a valid console=
argument?
Best regards,
Wolfgang Denk
