[Yocto][mickledore-6.1.36][iMX8MP] MIPI-CSI2 CRC Error

khang_letruong · ‎10-12-2024

Dear Forum,

We have a custom design of dual cameras using iMX8M Plus. So far, the first camera pipeline works acceptably:

But we are having weird image output on the second pipeline as below :

Enabling the MIPI-CSI2 debugging of the buggy pipeline gave :

The configuration of the 2 camera nodes in the device-tree is the same :

                        csis-wclk;
                };
        };
};

Both share the same MCLK (GPIO01_IO15) as in the reference EVK.

Do you think that this is a hardware related issue?

do you use dual ISI ? if you disable the first camera, is it ok for second camera?

if you disable the first camera, is it ok for second camera?

Do you mean to completely/physically remove the first camera and/or to disable the first ISP node in the device-tree for my use-case ?

I mean that you disable the first camera in the dts, only test the second camera

khang_letruong · ‎10-20-2024

Hi,

We found an issue on the hardware side.

Best Regards,

ok, I will close this thread since you find the root cause
