Doubts in DM368 IPNC camera


1.) I have purchased DM368 based IP camera from Appro.(model: Davinci DM368IPNC-IMX036)
    In the beginning, I was getting camera display and the complete gui on internet explorer  on the IP address
    To get the gui output i am following static ip procedure as described in the document.

2.) I referred to the document Users_Guide_IPNC_DM368_IMX036.pdf . I installed the linux kernel
on the board as described in the document.But after doing that i am not getting any gui or camera display output
at ip printenv command output on DM368 IPNC prompt is folows: 

DM368 IPNC :>printenv                                                          
bootcmd=nand read 0x82000000 0x700000 0xD00000;nboot 0x80700000 0 0x500000;boot0

Environment size: 504/131068 bytes    

4.) After booting the camera on with that kernel, following is the output on terminal.

Also, I would like to know few more things as follows,

a.) As of now, I am getting good image quality on the camera.But, the GUI has "eval version"
    written on the video stream. How long does the eval version last for, How would be the image
    quality after the evaluation period is over
b.) How can we improve the image quality once the eval period is over
    How can we develop our own image  processing algorithms on the camera
c.) How can we integrate those algorithms on the DM368 board and software package which we have got from Appro. What kind of environment setup is
    required for that ??
d.) There's a "Tuning Tool" provided with the development kit.How can we use that tool to improve image quality on the current set up.Is there any document
which explain how we can make use of that tool to tune image quality.
