Dear friends,
I have created new Linux kernel following steps specified in "DVEVM
Getting Started Guide (SPRUE668) for Davinci DM6446". When I booted
following information I got on screen..

In above message:
I was unable to understand following things.
1.
---------------------------------------
Machine: DaVinci EVM
Memory policy: ECC disabled, Data cache writeback
DM6443
----------------------------------------
Here DM6443 is mentioned, I was expecting DM6446. what may be the
problem. Is my perception is wrong.
2.
------------------------------------------------------
davinci_init:DaVinci V4L2 Display Driver V1.0 loaded

Revision:
----------------------------------------------------------------
How to rectify above problem ?
3.
When I connect my LCD display to board. If board is working it should
show a TI icon on left of the screen. Which is not seen now?
Please advice how to configure video display.
Please advice.
Thank you,
Basharath.
