Part Number: TDA4VM

Now we have some TDA4VM/J721EX boards and "psdk_rtos_auto_j7_06_02_00_21" sdk.

I can run single_camera usecase well with the config RIN0 and MIPI CSI0_D0.

How can i change the config to RIN1 and MIPI CSI0_D1?

Hello Guokai,

6.02 is very old. I strongly recommend you to switch to 7.2 SDK.

To select IN1, the simplest change is to set deserializer configuration to map the camera output to CSI VC #0. You will also need to set I2C slave aliases for sensor and serializer. Please refer to UB960 datasheet for register level details.

Regards,

Mayank

Thank you for your answer.

1.I have changed to 7.2 SDK.

2.I have mapped IN1 camera output to CSI VC #0 by setting the value of UB960 register 0x20 to 0x00.But there is not any output.

OK. Can you please probe CSI2 Rx pins and confirm that clock and data is received?
