TMDXIDK57X-LCD: Camera issue on IDK

Part Number: TMDXIDK57X-LCD
Other Parts Discussed in Thread: AM5728

Hello everyone,

I am using am5728 IDK Rev1.3B, there is a camera shipped with it (probably its ov2659 sensor), you can see related pictures in another question of mine in here.

I'm trying to find the problem and  making sure whether its the camera or the IDK, I'm using SDK Linux rt 4.9, my camera is not shown in /dev/ directory:

root@am57xx-evm:~# ls /dev/video*
/dev/video0   /dev/video10  /dev/video11
root@am57xx-evm:~#

the camera is not detected by i2c :

root@am57xx-evm:~# i2cdetect -y -r 0
     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
00:          -- -- -- -- -- -- -- -- -- -- -- UU --

20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

60: UU -- -- -- -- 65 -- -- -- -- -- -- -- -- -- --
70: -- -- -- -- -- -- -- --
root@am57xx-evm:~#

a) where can I find the related schematic for the camera module?

b) how can I make sure it's the camera and not the IDK?

c) if that's the camera, would change of the camera sensor (not the whole module) solve my problem?

any help would be appreciated.

B.R,

Alex.

    Hi Alex,

    What is the revision of the camera module you received? Did you order the camera separately or did it come with the IDK?

    Thanks, Bill

    Hi Bill,

    the camera came with the IDK, my colleague used it some months ago, it was functional, but now it's not working.

    camera version is 1.4 A. here is its pictures :

    and my IDK is REV 1.3B.

    Regards,

    Alex.

    Hi Alex,

    I found that the camera you have displayed is the camera developed with for the AM473x EVM. I think it is compatible with the AM57x IDK but I don't see anything that indicates it is delivered with the AM57x IDK. You stated that the camera was working previously. The camera schematic can be found on the AM437 schematic package found at the https://www.ti.com/tool/TIDEP0014 page.

    Regards. Bill

    Bill,

    thank you for your response. my colleague insists it was delivered with the am572x IDK package, I found this on am572x user guide :

    this may explain something. 

    is that possible to buy a new camera for am572x IDK separately? if yes, can you provide a link? 

    B.R,

    Alex.

    P.S: In the link that you provided, I can not see any schematic for the camera module, it only shows the header and related pins in EVM and their connections.

    is there any schematic for the camera module itself?

    Hi Alex,

    The camera module is not a TI product. You would have to contact the manufacturer to get schematic information.

    Hi Alex,
    I have confirmed that the camera is delivered with the AM572x IDK package. I'm sorry for the misunderstanding concerning that. I do not see a separate orderable part number for the camera.  I will continue to check and see if there is a method for replacing the camera. You did say it was working when the IDK arrive, correct?

    Regards, Bill

    It's ok, I understand.

    Thank you for your attention.

    yes, it was working some months ago.

    if there is no separate camera module to order, I may buy a new camera sensor for the current module, I found some  ov2659 sensors in here and here , however, their FFC cable seem slightly different, can you confirm whether they are compatible or not?

    this is my camera sensor:

    this is FFC of the camera sensor I may buy:

    are they compatible? 

    Regards,

    Alex.

    H Alex,

    It does not look like a compatible interface for the sensor on the camera module. I've been told that the camera sensor we used on the camera module is no longer available for purchase. We purchased a lifetime supply to accommodate our needs for the camera module. If you need a replacement for your camera module we may have one that can be sent. Do you have a TI FAE that you are working with? 

    Regards, Bill

    Unfortunately, I don't. I gave up on this camera module, I purchased another camera module available in the market with another sensor, I hope I can get it run with my IDK, I may open another issue for this purpose and ask some questions.

    B.R,

    Alex.
