Mageshwaran

and also for this post 


http://www.friendlyarm.net/forum/topic/4516


Kindly try to answer the fact...

I can imagine no response to the first post because it is a bit too
general.

It depends on which kernel you are running, whether or not you are happy
controlling the LED from userspace or not.

Have you got /sys/class/gpio 

in your root filesystem?  Then I'd suggest going to this page:

http://www.oselas.org/oselas/bsp/pengutronix/mini2440_bsp_en.html

and downloading the QuickStart.pdf and turn to section 8.4 or thereabouts.

Have you read through the many posts about using the cameras.  If so, ask
specific questions.

Yes.

Have you got /sys/class/leds/backlight  if so I will make the effort to
type out the commands.

A lot of the specific FriendlyArm modifications are closed source.

Have you tried searching for <power management source code>?

Tanks for ur kind info Mr.Davef 


I will try all those...



Tank u...

I don't want to control led in user space 
 
I want to run it in kernel space kernel (2.6.38)



>>  Have you got /sys/class/gpio 

 no such folder/file "gpio"

>>  Have you read through the many posts about using the cameras.  If so,

Yes but various solution for CMOS camera tell the exact page that is best
suited.

>>  Have you got /sys/class/leds/backlight  if so I will make the effort to

no such folder/file "backlight"

i have another doubt 

Is it support mini6410

> I don't want to control led in user space

Why?  

Have you got the config file for that kernel for use with the mini2440?

Sorry, I don't understand this response.

> no such folder/file "backlight"

This will probably stop progress.  

Does the config file for kernel have PWM and power management enabled in
it?

Ah, mini6410.  That changes everything for me as I have never worked with a
mini6410.

There is a BSP for mini6410 by Pengutronix.

You are welcome to ask questions and hope that someone with the relevant
experience will try to help you.


>> where i get this config file for mini6410 ?

Have you got the DVD with the mini6410?  Have you looked through the files
on it?  There should be config files for the different touchscreen types.

>> what is the output of the c-mos camera how can i take that output

Never worked with the camera.  I would suggest you read through some of the
camera threads, I recall different formats being discussed.

>> "This will probably stop progress."   I can't get this...!

You will probably need PWM enable in order to vary the touchscreen
backlight brightness.  Now, you have a number of words you can try out in
the <search> function at the top of the forum page.

Is it possible to develop applications with any other IDE other than ADS
for mini6410?

If yes what type of IDE is used..?

can u suggest me an IDE for Linux which is best suitable for driver
development...

If you are a developer you always must know what you are doing. So, just
use your favourite editor to create and modify the source files for the
driver. IMHO any kind of IDE will not free you from the knowledge you need
to do this job.
