I want to set Camera I/O of IMX8QXP to 10-bit.

Hello,

#I want to set Camera I/O of IMX8QXP to 10-bit.

So I want to know how to use 10-bit parallel CSI of IMX8QXP.
 
I can understand usage of 8-bit pallael CSI from the IMX8QXP Datasheet, 
but 10-bit parallel CSI is not mentioned.

Are there any information about 10-bit parallel CSI of IMX8QXP?

Thanks

Takahashi

Hi Takahashi,

The i.mx8QXP has 10-bit parallel CSI interface.

for a 12-bit camera.

you can connect the Camera D11-> D09 of imx8QXP and Camera D2-> D0 of imx8QXP.

leave the D0 and D1 of camera floating or to GND.

Hope this can do help for you.

Have a nice day

Hi b45499,

Let me confirm the signal mapping for 10bit mode of parallel CSI.

Is it correct?

also, we should be set the CSI_CTRL_REG[DATA_TYPE_IN] register as "0001b - UYVY bt656 10bit".

Is it right?

Hi Rita

Thanks for your reply.

I understand your advice.

According to the datasheet below, there are 8-bit parallel CSI from CSI_PI.CSI_D02 to CSI_PI.CSI_D09.

But I don't find CSI_PI_CSI_D00 and CSI_PI_CSI_D01.

https://www.nxp.com/docs/en/data-sheet/IMX8QXPAEC.pdf (page 123 , 140)

Could you tell me how to connect lower 2bit.

Camera D00 ->  floating or GND 

Camera D01 ->  floating or GND

Camera D02 ->  ?

Camera D03 ->  ?

Camera D04 ->  D02 of imx8QXP

Camera D05 ->  D03 of imx8QXP

Camera D06 ->  D04 of imx8QXP

Camera D07 ->  D05 of imx8QXP

Camera D08 ->  D06 of imx8QXP

Camera D09 ->  D07 of imx8QXP

Camera D10 ->  D08 of imx8QXP

Camera D11 ->  D09 of imx8QXP

Best regards

Takahashi
