Connect 2 C3188A modules on BeagleBoard expansion

michel TRAN

Hello,

I would like to connect 2 C3188A modules : http://www.quasarelectronics.com/c3188a-digital-output-cmos-colour-camera-module-omnivision-ov7620.htm

on BeagleBoard XM expansion connector.

I need to capture at least 30 frames per second on both ov7620 chips to make real time 3D reconstruction.

Could I do that with expansion connector or with camera connector on beagleboard XM (using multiplexer to connect both devices at the same time) ?

I would like to modify leopard driver
http://gitorious.org/beagleboard-validation/linux/blobs/validation-20100805/arch/arm/mach-omap2/board-omap3beagle-camera.c

using omnivision linux driver http://www.cs.fsu.edu/~baker/devices/lxr/http/source/linux/drivers/media/video/ovcamchip/

but I never develop ubuntu linux driver, how could I do that ? When I try to compile omnivision driver I have the following errors

$ make
make -C /lib/modules/2.6.35-ARCH/build M=/tmp/webcam/ov51x-jpeg-1.5.9 modules
make[1]: Entering directory `/usr/src/linux-2.6.35-ARCH'
  CC [M]  /tmp/webcam/ov51x-jpeg-1.5.9/ov51x-jpeg-core.o

compilation terminated.
make[2]: *** [/tmp/webcam/ov51x-jpeg-1.5.9/ov51x-jpeg-core.o] Error 1
make[1]: *** [_module_/tmp/webcam/ov51x-jpeg-1.5.9] Error 2
make[1]: Leaving directory `/usr/src/linux-2.6.35-ARCH'
make: *** [all] Error 2


Could you help me ?


Thanks you,

Best regards,

Hi Michel,

First of all it looks like you are trying to build the driver outside Linux, you have to provide all required build environment to build any driver. I would suggest you to do some google on "how to build", there are tons of pages available on this.

Also another quick suggestion is, move driver to kernel directory, hook up to kernel makefile and try building it there. Refer to any other sensor driver as a reference.

Thanks,

Vaibhav

Thank you Vaibhav for your answer.

I didn't find in beagleboard manual, any information about the expansion speed.
Could I expect to have about or over 27Mhz I/O operation rate through GPIO access ?

I would prefer, let someone from HW team conform this?

Thanks,
