Hi nvidia team: When I use Orin debug sensor(imx390)+max96717+max96712. On phy_mode is “DPHY”, Orin can get video; but On phy_mode is “CPHY”, Orin not get anything. On “DPHY” foundation, I set mode0 “phy_mode = “CPHY”;” [图片] On max96712 driver: I set 96712 work on c-phy , and set lane_polarit…

The configure set the BCA should be correct but don’t know why still have problem. Could you try lower speed like 1 or 1.5G

Hi ShaneCCC : Can you tell me where to set “POLARITY_SWIZZLE_CPHY” up？ I think it look like set “brick_config.lane_polarity” , so I set it from NVCSI_CPHY_POLARITY_ACB to NVCSI_CPHY_POLARITY_CBA, but Orin can not get mipi data. switch(lane_pol) { case NVCSI_CPHY_POLARITY_ACB: dev_info(csi->dev…

If you follow the design guide that could be compatible for CPHY and DPHY that shouldn’t need to configure the “brick_config.lane_polarity” Beside the index should be from 0 - 3

[image] ShaneCCC: brick_config.lane_polarity Is “POLARITY_SWIZZLE_CPHY1_A (control for lane 1): 010 = ABC to BCA” line to "brick_config.lane_polarity[1] " ? But where I can do set NVCSI_PHY_0_NVCSI_CIL_A_POLARITY_SWIZZLE_CTRL_0 bit 13:11.

brick_config.lane_polarity[0 -1] for POLARITY_SWIZZLE_CPHY0_A brick_config.lane_polarity[2 -3] for POLARITY_SWIZZLE_CPHY1_A

Hi ShaneCCC: I use next to set "NVCSI_PHY_0_NVCSI_CIL_A_POLARITY_SWIZZLE_CTRL_0 " bit [13:8] ; brick_config.lane_polarity[3] = NVCSI_CPHY_POLARITY_BCA; brick_config.lane_polarity[3] = (brick_config.lane_polarity[3] << 3) + NVCSI_CPHY_POLARITY_ABC; dev_info(csi->dev, “ncs:: CPHy mode: default 0…

Hi ShaneCCC Thank you for your help！ Next pdf file is my hardware design. ORIN_cpy_2.pdf (28.0 KB) help me to set Orin polarity swizzel, thanks!

Dose it connect to CSI0? What’s the port-index? Does it 3 lane configure?

[image] ShaneCCC: port-inde Yes connect CSI0 and port-index is “0” , 3lane(trio) . { 1trio: csi0_D0_P csi0_D0_N csi0_CLK_P 2trio: csi0_D1_P csi0_D1_N csi0_CLK_N 3trio: csi1_D0_P csi1_D0_N csi1_CLK_P } this is my sensor dtsi tegra234-p3737-0000-camera-ncs-cphy-ov5640_imx390.t…

Could you remove below those configure to use default to confirm. brick_config.lane_polarity[1] = NVCSI_CPHY_POLARITY_ACB; brick_config.lane_polarity[2] = NVCSI_CPHY_POLARITY_ACB; brick_config.lane_polarity[3] = NVCSI_CPHY_POLARITY_ACB;

CPHY does not work , but DPHY can work ON same Hardware environment

Which trio need polarity swizzle for your design?
