Linux/AM5728: AM5728

Hello,

Just to confirm you are using mt9t11x based camera module right?
Will be nice if you let me know the PSDK version that you are using.

Thank you for your reply

it seems that problem with sensor board (camera sensor is connected tightly with screws), their is no loos connection and orange LED on sensor module is also ON

Please suggest me how to proceed

You do not see nothing because you must load the dtb file.

You could load the dtb file by following this guide:
http://processors.wiki.ti.com/index.php/How_to_Change_dtb_File

but load the dtb file for mt9t111(am57xx-evm-reva3-cam-mt9t111.dtb). You do not need to cp(copy) the dtb files on the board since prebuild - images are already included.
When you add fdtfile=xxx.dtb you must restart the board.
Run ls /dev/video* you must see /dev/video1 if you don't execute dmesg | grep mt9t again and let me know.

This line mt9t11x 4-003c: Product ID error ffffff87 indicates that your sensor board has either gone bad or the sensor has turned loose.You can try snapping the sensor board tightly to the base board.
Please, try reconnect the module and use the screws to fix the camera module also.
If you have ov10635 based sensor board, you could try with it also.

I tried Connecting sensor tightly with screws, but still facing same issue

the .dbt file mentioned is already avilable in mmcblk0p1, we did restarted board but still facing same issue with SDK version 5

Hello,

Just to confirm now on PSDK 5.x you have output when you execute this : dmesg | grep mt9t
and you are observing the same error as on psdk 4.3 right?

if i am executing same on PSDK Version 4.3 i am getting above error

Have you edited uEnv.txt? You must see prints when you are loading the correct dtb file.

Please, check the thread in my first answer. There is explanation what you must load on psdk5.0 and how was solved.
