New camera ISP bring up for IMX8MP

Dear NXP.

We need help for Camera Bring up.

We use PI6008K (ISP), PK5210N(CMOS). But do not work camera preview.

We attached files.(Datasheet, dts and mipi csi clk waveform).

we not received frame  sync and rx interrupt , guess Dphy does not working

1. frame format is YUV422 8bit 

2. 

          data-lanes = <4>;

          csis-hs-settle = <13>;

          csis-clk-settle = <2>;

 

3. Master send mipi clock is 148M

 

We log :

 mxc-mipi-csi2.0: Frame End events: 0

 mxc-mipi-csi2.0: Frame Start events: 0

 mxc-mipi-csi2.0: Non-image data after odd frame events: 0

 mxc-mipi-csi2.0: Non-image data before odd frame events: 0

 mxc-mipi-csi2.0: Non-image data after even frame events: 0

MIPI clk output of PI6008K (ISP) is continuous mode like below picture.

Please give us solution.

ISP MIPI CLOCK is only continuous mode. So ,Do not test non-continuous mode.

Let me know the AP setting for continuous mode.

Please refer to the https://www.nxp.com.cn/docs/en/application-note/AN13573.pdf section 2.5 about the mode transitions.

in continuous clock mode, there may only be one LP state at the very beginning, and clock lane will always work in HS mode later. So it's better to make sensor work in LP state before enable 8MP DPHY. otherwise, DPHY may not detect the HS mode, then it can't receive data from sensor.
