Here are the final debug statements which we are seeing in the hyper terminal.
Can you post the full logs WITHOUT your debug prints. What is the
toolchain you are using?
Please find the attached FULL log file without our own messages.

If we load 2.6.10 kernel image, we are getting login prompt in the
hyper terminal on the same Phytec board.
You can isolate the problem by writing a small utility(blinky) which
would blink some LED on the board and then pass (init = /sbin/blinky)
it in your kernel command line.
We are assuming that the kernel is completely booted, in 2.6.32
kernel, without any issues as it entered into cpu_idle state. We are
guessing that there is an error in the file system sources (i.e.
sbin/init). Unfortunately, we do not have the sources for the
available file system and we have downloaded the file system from the
following Phytec link.

Please provide some insight to find out the reason for not getting login prompt.

Thanks and Regards,
Srinidhi M.
