Camera support on OMAP3530

Other Parts Discussed in Thread: OMAP3530, DM3730

I use the Gingerbread-dev-Kit with 2.6.37 Kernel on OMAP3530，
but know I hope someone can help me on porting a driver for this OV3640...

I find that there is the driver for OV3640 in linux 2.6.32, have to port it to linux 2.6.37?

have to modify board-omap3beagle-camera.c for adding OV3640 support to i2c subsystem.?

then do I select devkit 1.0 release or devkit 2.0 ?

"http://e2e.ti.com/support/embedded/android/f/509/t/111591.aspx

1. rowboat gingerbread devkit 1.0 release supports camera on beagleboard "

Every guide or hint will be helpful!

Hi,

I would suggest you to use our below mentioned latest Android release

http://software-dl.ti.com/dsps/dsps_public_sw/sdo_tii/TI_Android_DevKit/TI_Android_GingerBread_2_3_4_DevKit_2_1/index_FDS.html

Please refer to below mentioned porting guide for more details.

HI,

why do you suggest use DevKit_2.1? I use OMAP3530 now and will use DM3730 later.

DevKit_1.0 support for the OMAP35x EVM, AM35x EVM, AM37x EVM, DM37x EVM, Beagleboard Rev Cx and Beagleboard XM and TI DVSDK 4.01 for DM3730 , but DevKit_2.1 This release supports AM35x, AM37x Texas Instruments AM37x EVM (on the Mistral Rev G AM3715EVM) Texas Instruments AM35x EVM Beagleboard Rev Cx Beagleboard XM Rev A/B/C .

DevKit_2.1 do not support DM3730. I think that DevKit_1.0 support better for OMAP3530 and DM3730 than DevKit_2.1?

jian

Hi Jian,

As you mentioned that you are using OMAP3530 so I mentioned about 2.1 release.

If you are using DM3730 then you may stick to 1.0 release.

If you want latest components you may refer to below wiki page.

HI,

thanks,

(DVSDK) 4_01_00_09 for the OMAP3530 platform is based on linux 2.6.32, So I must use linux 2.6.32?

As you mentioned that DVSDK is supported on Devkit 2.1.

but I do not find that it support OMAP3530 on Devkit 2.1 and Devkit 1.0.

Will you port (DVSDK) 4_01_00_09 for the OMAP3530 platform from linux 2.6.32 to linux 2.6.37? or it is support on DevKit 2.1 for OMAP3530 later.?

Regards,

Jian

Hi Jian,

DVSDK is not supported on 2.1 for OMAP3530 platfrom.

Right now there are no plans to port DVSDK on 2.6.37 kernel of OMAP3530 platfrom.

Please stick to 1.0 release if you are using OMAP3530 platform.
