about MIPI CSI2 of i.mx6

Hello,Community

I have some questions about MIPI CSI2 of i.MX6.

Q1)

According to Figure 19-6. RGB666 data reception in IMX6DQRM(Rev.3), MIPI CSI2 can receive data in RGB666 format.

But according to register of IPUx_CSI0_SENS_CONF, it looks like that the IPU CSI cannot receive RGB666 data.

Could you explain it for me?

Q2)

According to Table 19-1. Input signals to CSI2IPU ,data_type for RGB data is 0x20~0x27.So when data format is RGB666,the data_type is what? And how to set it?

Thank you!

Hi ZongbiaoLiao

1. you are right, not all MIPI CSI2 formats are supported by IPU.

2. according to MIPI-CSI2 specification (Version 1.01.00 9-Nov-2010) Table 16

RGB666 data_type =0x23 . These data is set by transmitter (sensor) in packet header .

Hi, Igor

Thank you for your reply!

1. you are right, not all MIPI CSI2 formats are supported by IPU.

Does it mean that we cannot use a MIPI Camera sensor that output RGB666?

Thank you!

Hi ZongbiaoLiao

I believe it can be used, with IPU could handle it

as generic format.

Hi igor

Thank you for your reply!

About generic data, I have two questions.

Q1)

If set CSI0_SENS_DATA_FORMAT to generic data, then how to set CSI0_DATA_WIDTH?

Q2)

If RGB666 input is received as generic data ,then how to resolve it back to RGB666 format(Need I write some custom code)?

Thank you!
