That's lead to the question I've asked before, as there are some
Hardware dependencies:
- *** How do you connect the hi253 camera to your board?
Check the vendor document to know on which bus (USB, PCI or
i2c) the hi253 used to connect to the system.
Normally the hi253 code should help you to identify the bus used to
connect to the system.
What is for sure is that the mt9v113 does use i2c bus to connect to
the system (e.g. your board).

I have checked existing HAL camera on Link that I posted. But on file:
V4L2camera.cpp only support 3 sensor camera: mt9v113, mt9t111, tvp514x.
1 - On hi253 driver, it register with v4l2 interface with funtion:
- v4l2_int_device_register(&hi253_int_device);
2 - On mt9v113 driver, it register with v4l2 inter with 2 functions:
- /*
* Register as a subdev
*/
v4l2_i2c_subdev_init(&mt9v113->subdev, client, &mt9v113_ops);
mt9v113->subdev.flags |= V4L2_SUBDEV_FL_HAS_DEVNODE;
/*
* Register as media entity
*/
mt9v113->pad.flags = MEDIA_PAD_FLAG_OUTPUT;
ret = media_entity_init(&mt9v113->subdev.entity, 1, &mt9v113->pad,
0); f
I don't understand about this different. I am stucking here. Can you
show me a solution?

I just answered your other thread!
Did you have any camera comes with your board today?
Check and locate your existing HAL camera source code. (i.e. Did
you see any camera folder within the <panther-bsp>/hardware folder ?)
Sure that it's better if you can get the HAL code from the vendor.
(make sure that the HAL can drive the V4L2 driver).

Thank you verry much!
I am clearly steps in integrate process.
I was success re-build kernel that add hi-253 driver. But i don't
understand about:
1 - Is Hi-253 driver compatibility with HAL camera at patch:
http://processors.wiki.ti.com/images/6/6c/0001-HAL-camera-support-added-for-beagleboard.patch.gz
<http://processors.wiki.ti.com/images/6/6c/0001-HAL-camera-support-added-for-beagleboard.patch.gz>
or i have to contact with vendors for HAL camera?
Thank you!

In clear you have to do these below steps:
-------------------------
The kernel part
------------------------
1 - Integrate the hi253 device driver into your Panther board
kernel
a - Add the driver source code to your kernel
b - Configure OMAP to recognize your hi253 camera
c - Enable the Camera Module to your kernel config
The patch for these steps have been provided in the TI's
porting guide at this link :
http://processors.wiki.ti.com/images/a/aa/0001-camera-sensor-support-mt9v113-for-beagleboard.patch.gz
<http://processors.wiki.ti.com/images/a/aa/0001-camera-sensor-support-mt9v113-for-beagleboard.patch.gz>
All you have to do is apply the patch to your kernel.
2 - Re-build your kernel
You can refer to this link for How to build the kernel :
http://processors.wiki.ti.com/index.php/TI-Android-FroYo-DevKit-V2_UserGuide#Kernel
<http://processors.wiki.ti.com/index.php/TI-Android-FroYo-DevKit-V2_UserGuide#Kernel>
----------------------
android part
---------------------
3 - Add the Camera HAL interface to your android plateform
Per TI's porting Guide, the patch is here :
http://processors.wiki.ti.com/images/6/6c/0001-HAL-camera-support-added-for-beagleboard.patch.gz
<http://processors.wiki.ti.com/images/6/6c/0001-HAL-camera-support-added-for-beagleboard.patch.gz>
Also per TI's porting guide for Froyo release the patch
should be applied at <ANDROID_ROOT>/hardware/ti/omap3/camera,
to check on your android plateform development source code
the V4L2 part.
4 - Re-build the android system and give a try
Hope this clarified a little bit for you.
