AM572x GP EVM Camera not detected

Other Parts Discussed in Thread: AM5728, TMDSCM572X

Hi all,

I'm experiencing an issue that for me it's more likely a hardware issue, camera sensor is just not visible on the I2C bus as if it wasn't connected when the AM5728 EVM board is cold, so communication can't be done and the device can't get probed and registered successfully. I'm using TI's image and the output log is the following:

#) mt9t11x 4-003c: input-clock-freq: 32000000
#) mt9t11x 4-003c: pixel-clock-freq: 96000000
#) vip 48990000.vip: loading firmware vpdma-1b8.bin
#) vip 48990000.vip: VPDMA firmware loaded
#) mt9t11x 4-003c: Product ID error ffffff87

After heating the board externally with air at 140°F for around 30 minutes or more if no luck the camera starts being visible on the I2C bus and the device driver gets probed and registered successfully as shown in the following output log:

#) mt9t11x 4-003c: input-clock-freq: 32000000
#) mt9t11x 4-003c: pixel-clock-freq: 96000000
#) mt9t11x 4-003c: mt9t111 chip ID 2680
#) vip2-s0: Port A: Using subdev mt9t11x for capture
#) vip2-s0: device registered as video1
#) mt9t11x 4-003c: mt9t11x sensor driver registered !!

I have seen the same behavior with different combinations of three AM5728 EVM boards and two AM57xx EVM Camera boards. It seems that some strange physical phenomenon is occurring on the I2C lines that makes communication successful only when those lines are heated.

Has anyone experienced something similar? I would like to get this issue solved.

Regards,

Carlos Gomez

    Hi,

    Thanks for your answers! Hope the factory team can provide a solution for this issue. The camera sensor should be detected on the I2C bus the first time that I turn on the  AM5728 EVM. I'll be waiting for a response.

    Thanks again,

    Carlos

    hi Carlos,
    I use the same evm board, and get the same erro info (mt9t11x 4-003c: Product ID error ffffff87) ,but I did not get right I2C info anytime,

    have you fixed this problem?

    thanks.

    Hi Panxi,

    No, I haven't fixed this problem. The way I found to get it working is to heat the board externally with air at 140°F or by running applications with high CPU or GPU load for several minutes or even hours and rebooting the board during that process until get the I2C bus detecting the camera sensor.

    Regards,

    Hi Carlos,

    I got the same issue with the video capture device on AM5728 EVM. I tested it deeply and finally I conclude that the error is caused by something wrong with the TMDSCM572x camera module itself. I test the issue with 3 cameras, one camera works fine with no errors each time I tested it. The other two cameras fails 16 times of 20 tries in average. The test consist in boot the board 20 times with each camera and look if the device is recognized by the system, I repeat the test with other EVM to discard another possible source of error. The error is completely aleatory, with a big tendency to failure. 

    I think that maybe this camera modules have a production error or low quality control, because from 3 new brand cameras, only one works fine (This can´t be only bad luck). 

    I hope that helps you, because I spend a lot of time figuring out this issue.

    Hello,
    I am using AM57x SDK 3.02.00.05 on GP EVM. I cannot get the camera to work? I did some cursory searching and it looks like it is registered during boot but i'm not sure if i need to run 'insmod'. I am still looking for 'vip driver users guide for this SK'.

    I am using 'AM57xx EVM Camera Board Revision A1'.

    Thanks for any guidance.
    Marc
