OMAP3530 EVM rev.G - problem running camera module

Zvika,

Please comment out the IOCTLS which would not be applicable for this set-up.

Regards, Punya

Thanks, I already did so.

The problem is that STREAMON ioctl doesn't work which enables streaming.

Do you know of a fast way to enable it (like writing to some register?).

One more thing, I digged in to the kernel and to see how the device registers during the boot, when it registers I see a connection between CCDC and mt9t111 sensor. but when I run the application (i.e. open the device file) I see that the device is CCDC but I can't find anything related to the sensor (it seems that none of the ISP devices related to the video 4 linux dont relate to the sensor).

Regards,

Zvika

Zvika,

In the media controller framework, each hardware clock is listed as an entity. You are required to link these elements in application space before you run the loopback example. Have you linked these pads? If not, please refer the application code at git://git.ideasonboard.org/media-ctl.git.

Hi Zvika,

I used the same OMAP 3530 EVM board Rev. G and kernel to test LI-3M02CM camera module.  But I can't see "sensor mt9t111 detected" message.  

Kernel always show "Unable to detect mt9t111 sensor" message.  

I put the LI-3M02CM camera module on J34 connector on OMAP 3530 EVM board and set JP1 to 1-2.

Do I need to set other adjustment on EVM board?

Thanks,

Hank

Hank,

if you take a look at the schematics or the arch/arm/mach-omap2/board-omap3evm.c file, you will notice that the JP1 jumper should be configured for 2-3 to enable i/p from J31.

Hank,

I just noticed that you mention J34 connector, by this do you mean the J31LI-3M02 connector on Rev G EVM?

Regards, Punya

Punya,

NO, I mean J34 LI-3M02 connector connector on Rev G EVM.

Just like attached image( blue color area).

Thanks.

Hank

Hi Hank,

I didnt change anything physical at all and left the EVM just as I got it.

Please note that J1 jumper should be on MICRON/LI CONN. and not on LI-3M02CM (opposite to the logic...)

Punya,

Now,  I can detect the LI-3M02 camera module.

But I run the LI's debug tool "saMmapLoopback" .

System show some message as below.

Capture: Opened Channel

Capture: Current Input: camera

Capture: Input changed to: camera

Capture: Capable of streaming

Capture: Number of requested buffers = 3

Capture: Init done successfully

Display: Opened Channel

Display: Capable of streaming

VIDIOC_S_CTRL: Invalid argument

Error in opening display device

Hank,

Please verify your application parameters.
