嗨，我使用了Jetpack5.1.4的版本，参照着上次Jetson 5.1.1的更改方法更改了设备树，然后将生成的dtb文件替换到源码里，同时使用表格内的文件生成了pinmux.dtsi等3个文件，更改了配置文件，我发现配置文件中相比于5.1.1多了一行
“OVERLAY_DTB_FILE="${OVERLAY_DTB_FILE},tegra234-p3768-overlay.dtbo”我不知道这一行是否会对结果有帮助？
DEFAULT_EMC_FUSE="0";
PINMUX_CONFIG="pinmux.dtsi";
PMC_CONFIG="padvoltage.dtsi";
BPFDTB_FILE="tegra234-bpmp-3767-0000-a02-3509-a02.dtb";
DTB_FILE="tegra234-p3767-0000-p3768-0000-a0-modify.dtb";
TBCDTB_FILE="${DTB_FILE}";
EMMC_CFG="flash_t234_qspi_sd.xml";
OVERLAY_DTB_FILE="${OVERLAY_DTB_FILE},tegra234-p3768-overlay.dtbo";
ODMDATA="gbe-uphy-config-9,hsstp-lane-map-3,hsio-uphy-config-0";
然而开机后PCIE C9 1-Line无法使用，以下是我的开机日志和反编译生成的文件，我注意到一个错误：Failed to get slot regulators: -517
能帮我看看是什么原因吗？
