ov5640_mipi not found ?

[wenmingfeng]

When I connect the ov5640_mipi camera with imx6dl customized board, kernel can not found the camera.

I got below log. I am using the fsl yocto imx-4.1-krogoth rlease.

galcore: clk_get vg clock failed, disable vg!

Does someone else encounter this issue?

Thanks!

Hi igor,

Thanks for your document. Question here is that what we used the same camera and sensor as the reference sabresd board, the only change is we use I2C1 and changed the RST,PWN pin no other change. I already modified the DTS file for the pin change and move the ov564x_mipi from i2c2 to i2c1 node. the log shows operation to i2c bus error.

The I2C1 bus we already assign with eeprom, sdcard control, it works.

Anyone has same issue or I am missed something?

Thanks!
