Does i.MX6 MIPI-CSI I/F can support non-continuous clock LPS mode ?

Danube · ‎10-08-2015

Hi

Yellow ---> MIPI_CSI_CLK

Green ---> MIPI_D0

Base on Debug steps for customer MIPI sensor.docx

3. Check every register of MIPI CSI-2 with MIPI_CSI_N_LANES ~ MIPI_CSI_DATA_IDS_2.

Tips:

In ov5640_mipi case (2 data lanes are used), the correct MIPI_CSI_PHY_STATE is 0x330 (and the bit 11 is jumping between 0 and 1, the value is jump between 0x330 and 0x300.

I think 0x330 and 0x300 is base on continuous clock LPS mode. Right ?

If non-continuous clock LPS mode , the value is 0x300 , 0x630 , Right ?

Hi Appolo

I think you are right, non-continuous clock is supported and

clock lane supports stop state.

Best regards

We had connect to ISP.

We had set color bar command to ISP , and it had output.

We had check some iMX6Q MIPI_CSI Registetr

It is "0" in MIPI_CSI_ERR1/2.

MIPI_CSI_PHY_STATE : 0x300 , 0x630

IPUx_INT_STAT_1 is 0x00800000. (It is not the same as OV5640 , 0x00001000)

We can't see color bar in i.MX6 Display. (Just only block color in Display)

(System just only one MIPI_CSI. No parallel camera)

(My test command is

./mxc_v4l2_overlay.out -di /dev/video0 -iw 1920 -ih 1080 -ow 1024 -oh 768 -fr 30 -m 5 -r 0 -fg

IPU1_CSI1_DI , IPU1_CSI1_SENS_CONF , IPU1_CSI1_SENS_FRM_SIZE , IPU1_CSI1_ACT_FRM_SIZE is the same as demo board.

Does any register need to check ?

Hi Appolo

sorry, I got updated info:

IC designer confirmed: The Non-continue clock transmission can’t be support by our DSI in i.mx6 series
