我们使用UPD720201进行pcie转usb的功能，如下是原理图，接在PCIe C1，重新刷系统之后，系统一直启动失败

img_v3_02ec_7fd89df5-cf03-497d-a8cc-992ff9e5965g1196×597 155 KB

如下是启动失败的dmesg
一直重启.txt (18.4 KB)
只有当我禁用如下配置，系统才能正常启动，如何配置UPD720201，才能实现pcie转usb,并且系统正常启动
pcie@14100000 {
status = “disabled”;

	nvidia,disable-aspm-states = <0xc>;
	nvidia,enable-power-down;
	nvidia,disable-clock-request;

	nvidia,max-speed = <2>;
	max-link-speed = <2>;

#if TEGRA_PCIE_VERSION >= DT_VERSION_2
phys = <&p2u_hsio_0>;
phy-names = “p2u-0”;
#else
phys = <&p2u_0>;
phy-names = “pcie-p2u-0”;
endif
};

这是启动失败的dmesg日志信息

開機失敗的log看起來是卡在UEFI.

常用的一招是你在UEFI dtb裡面把pcie C1關掉. 但在kernel dtb把C1打開
(請參考board config 裡面的 TBCDTB_FILE欄位)

這樣的話應該就能用了

5

@WayneWWW 你好，关于(Please refer to the TBCDTB_FILE field in the board config)这部分的链接在那里，我是在tegra194-p2888-0000-a00.dtsi文件修改，disabled pcie@14100000 ，如下，板子可以正常开机，但是修改为status = “okay”;就开不了机了

	pcie@14100000 {
		status = "disabled";

		nvidia,disable-aspm-states = <0xc>;
		nvidia,enable-power-down;
		nvidia,disable-clock-request;

		nvidia,max-speed = <2>;
		max-link-speed = <2>;
#if TEGRA_PCIE_VERSION >= DT_VERSION_2
		phys = <&p2u_hsio_0>;
		phy-names = "p2u-0";
#else
		phys = <&p2u_0>;
		phy-names = "pcie-p2u-0";
#endif
	};

@WayneWWW ，我现在参考的修改是https://docs.nvidia.com/jetson/archives/r35.6.0/DeveloperGuide/HR/JetsonModuleAdaptationAndBringUp/JetsonAgxXavierSeries.html?highlight=pinmux#the-jetson-agx-xavier-devkit-default-pcie-configuration， Pinmux也修改了

7

Xavier的話需要額外的patch 作法類似以下

8

@WayneWWW ,你好，谢谢你的指导，我想问一下uefi的dtb和dts使用的是那一个文件

9

跟你的kernel dtb一樣 只是它會被燒去不同partition.

我上一個comment給你的patch就是在講這件事

TBCDTB_FILE那個欄位是給你的UEFI dtb用的

10

那按照你的意思，就是kernel dtb和uefi dtb使用的设备树配置都一样，只是烧去不同的partition，所以需要修改两次，UEFI dtb把pcie C1关掉，kernel dtb把pcie C1打开，都是基于同一个文件就行，是这个意思吗？修改flash.sh 文件的补丁之后，下面是我使用的jetson，烧录命令是：sudo ./flash.sh -r -k bootloader-dtb jetson-xavier mmcblk0p1 ？是这个吗？

11

是的 你的理解是對的

flash command也正確

12

@WayneWWW ,你好，我更新到最新的jetpack5.1.4版本，在烧录bootloader-dtb遇到一些错误，错误如下：

 Writing partition bootloader-dtb with tegra194-p2888-0001-p2822-0000-uefi_sigheader.dtb.encrypt [ 532544 bytes ]

13

这个partition size 在Linux_for_Tegra 目录下那个文件修改的
