How Can I control Sensor I2C(Sysclk2) to DM388(DM385)?

coby Park

Hello.

I'm Coby.

I have Refernce Kit DM388IPNC + IMX136.

I Changed Camera Image Sensor insted of IMX136.

Image Sensor(Camera) does not operate. The reason is "CAM_EXT_CLK" not operate.

So I2C does not operate.

How Can I control "CAM_EXT_CLK" to Mclk operate?

i am not quite understand your question.

You mentioned that you have changed the sensor, so what is the part number and what modification you have made to the software ??

Changing the sensor module should no affect the I2C clock I think, unless there is something changed but you didnt noticed.

BR,

Eason

Pin 7 EXT_CLK is not operate. Level is low.

Can I control EXT_CLK (CLKOUT0) operate?

I assume that you are not modifying any software, that the ext_clk should keeping output the clk.

However, to isolate this issue, I will suggest you disconnect the sensor board and check if there will be the signal.
