NVMe enumeration order

Orin Nano，R36.4.3（Jetpack6.2）环境，在自制载板上，PCIe的C1 和C7，各自连接到一个NVMe硬盘接口。两个NVMe位置，都能正常启动系统。

因为硬件结构上，将C7定义为系统盘，C1为数据盘。导致了系统盘符会有发生变化的情况，如下：

在单接系统盘时，C7→nvme0，

当接两个硬盘时，C1–>nvme0，C7–>nvme1

我想更改枚举顺序，让C7排到C1前面枚举，从而能固定编号为nvme0，请问应该怎样设置？

Hi,

We do not provide such a setting.
Please flash the system using the specific NVMe device number.
For example, replace nvme1n1p1 with nvme0n1p1 if that is your system disk.

sudo ./tools/kernel_flash/l4t_initrd_flash.sh --external-device nvme1n1p1 \
  -c tools/kernel_flash/flash_l4t_t234_nvme.xml \
  --showlogs --network usb0 jetson-agx-orin-devkit external

Thanks
