ODM Data for Cfg#5

What is the ODM Data for cfg#5? I have gone through PLATFORM ADAPTATION AND BRING-UP GUIDE but was not able to determine the data.

Kindly suggest a solution.

Update

I was able to get the ODM data as 0x2090000 and here is my code modification

gpio@2200000 {
		sdmmc-wake-support-input {
			status = "okay";
		};

		sdmmc-wake-support-output {
			status = "okay";
		};
		pcie0_lane2_mux {
			status = "okay";
		};
	};



	fixed-regulators {
		regulator@1 {
			gpio = <&tegra_main_gpio TEGRA_MAIN_GPIO(P, 6) 0>;
                };
	};

	sdhci@3400000 {
		cd-gpios = <&tegra_main_gpio TEGRA_MAIN_GPIO(P, 5) 0>;
		nvidia,cd-wakeup-capable;
	};

	i2c@3160000 {
		ina3221x@40 {
			channel@0 {
				ti,shunt-resistor-mohm = <10>;
			};
			channel@1 {
				ti,shunt-resistor-mohm = <10>;
			};
		};
		ina3221x@41 {
			channel@0 {
				ti,shunt-resistor-mohm = <20>;
			};
			channel@1 {
				ti,shunt-resistor-mohm = <10>;
			};
			channel@2 {
				ti,rail-name = "VDD_SYS_DDR";
				ti,shunt-resistor-mohm = <10>;
			};
		};
	};

	ahci-sata@3507000 {
		gpios = <&spmic 7 0>;
	};

pcie-controller@10003000 {
		pci@1,0 {
			nvidia,num-lanes = <2>;
			status = "okay";
		};
		pci@2,0 {
			nvidia,num-lanes = <1>;
			status = "okay";
		};
		pci@3,0 {
			nvidia,num-lanes = <1>;
			status = "okay";
		};
	};


xhci@3530000 {
		phys = <&tegra_xusb_padctl TEGRA_PADCTL_PHY_UTMI_P(0)>,
			<&tegra_xusb_padctl TEGRA_PADCTL_PHY_UTMI_P(1)>,
			<&tegra_xusb_padctl TEGRA_PADCTL_PHY_USB3_P(1)>;
		phy-names = "utmi-0", "utmi-1", "usb3-1", "usb3-1";
	};


pinctrl@3520000 {
	    pinmux {
		usb3-std-A-port2 {
			nvidia,lanes = "usb3-1";
			nvidia,port-cap = <TEGRA_PADCTL_PORT_HOST_ONLY>;
			status = "okay";
		};
		e3325-usb3-std-A-HS {
                    status = "okay";
		};
	};
      };

I was able to compile and flash my device but was not successful.
Is there any issue or am i missing something?

What do you means not successful?

vishwanath.nm,

Please do not write a phy name that does not have matched phys.

xhci@3530000 {
		phys = <&tegra_xusb_padctl TEGRA_PADCTL_PHY_UTMI_P(0)>,
			<&tegra_xusb_padctl TEGRA_PADCTL_PHY_UTMI_P(1)>,
			<&tegra_xusb_padctl TEGRA_PADCTL_PHY_USB3_P(1)>;
		phy-names = "utmi-0", "utmi-1", <b>"usb3-1", "usb3-1";</b>
	};

@ShaneCC I was able to compile and flash the device but was not able to see any of the changes.
I have a custom carrier board which is designed for cfg#5. I could not detect any of the PCIe or USB lanes.

@WayneWWW I realized that mistake and corrected it, still no results.

You could check the runtime dtb by checking /proc/device-tree.
