TX2 3130000.serial cannot use after updating JP version

[suchb]

Hi,
TX2 runing JP4.2 3130000.serial- ttyTHS3 is working, and when JP version upgrade to JP4.6 3130000.serial- ttyTHS3 can’t recvice any data.
dmesg about uart is the same:

nvidia@nvidia:~$ dmesg |grep serial

could someone please help me?

Thanks.

hello suchb,

I don’t see any changes to update serial@3130000.
however,
could you please have a try to modify the device tree sources as following.

        serial@3130000 {
                compatible = "nvidia,tegra186-hsuart";
+               dma-names = "rx", "tx";
                status = "okay";
        };

Hi,JerryChang

change tegra186-quill-common.dtsi as below,

        serial@3130000 {
                compatible = "nvidia,tegra186-hsuart";
-               dma-names = "tx";
+               dma-names = "rx", "tx";
                status = "okay";
        };

serial@3130000 still can’t work.

update

    gpio@2200000 {
		wifi_over_pcie {
			gpio-hog;
			gpios = <TEGRA_MAIN_GPIO(R, 4) 0>;
			output-low;
			label = "wifi-over-pcie";
-			status = "disabled";
+			status = "okay";
		};
