[WayneWWW]

Device tree looks correct. Better checking on newer release.

[chengcheng2015]

application only support in jetpact4.2.2. so must solve this issue.

[kayccc]

The JetPack 4.2.2 was released at 2019-Aug, that’s really too old to support by now.

[chengcheng2015]

pls help me, maybe need check anywhere?

[chengcheng2015]

先后验证了jetpack4.2、4.3、4.4版本，验证方法如下：1、把对应jetpack版本 kernel 源码使能pcie c4: pcie@14160000 {
status = “okay”;

            vddio-pex-ctl-supply = <&p2888_spmic_sd3>;
            nvidia,disable-aspm-states = <0xf>;
            nvidia,enable-power-down;
            nvidia,disable-clock-request;

            nvidia,max-speed = <4>;

            phys = <&p2u_8>,
            <&p2u_9>;

            phy-names = "pcie-p2u-0", "pcie-p2u-1";
    };

然后编译出kernel dtb，然后sudo ./flash.sh jetson-xavier mmcblk0p1烧到模组，启动后从串口可以看到卡在：

2、最后尝试到jetpack4.5版本后（包括4.6.1），同样使能pcie c4后就不存在上述问题了。在4.5版本应该解决了上述问题，还请RD开放有关在jetpack4.5
