Hi, is it on your own custom carrier board? Which option of below do you use? Do you know how to set the dts?
是在我们定制的载板上，我们选的是选项2，把x2改成2个x1，dts不知道怎么修改
please refer to the post here for C7 and C9.
And also the document

你好，p3767.conf.common这个文件是在源码目录下的哪里？
在你的host BSP 目錄下面.
是的 還要調整phys跟phy-names.
pcie@141e0000 {
/*
* C7 x1
*/
status = "okay";
phys = <&p2u_gbe_0>;
phy-names = "p2u-0";
};
pcie@140c0000 {
/*
* C9 x1
*/
status = "okay";
phys = <&p2u_gbe_1>;
phy-names = "p2u-0";
phys与phy-names是在哪里调整？也是在pcie dtsi中嘛，在这个文件里面我没有看见这2个名字，是要自己添加嘛？
soc底下的東西是所有t234 soc共同用的
platform底下是各個平台(Orin AGX/Orin NX/Nano).
platform會被包在soc後面生效.
所以你在soc那包的dtsi找不到東西的時候, 請去platform那邊找
p3768是Orin Nano/NX系列
concord是Orin AGX
common是全部共用的一些dtsi
其實正常的流程是你要先知道你的板子到底在用哪個device tree.
你再用那個device tree回去trace code.
flash to nvme
sudo ./tools/kernel_flash/l4t_initrd_flash.sh --external-device nvme0n1p1 -c
tools/kernel_flash/flash_l4t_external.xml -p "-c
bootloader/t186ref/cfg/flash_t234_qspi.xml" --showlogs --network usb0 p3509-
a02+p3767-0000 internal
因为我们用的烧写程序命令是这个，所以我判断我们所使用的dts文件是图片所示
okok. 那就加吧
没事了，搞定了，没有更新原来的设备树
