Debugging Jetson nano with qemu Unable to Mount Root File System

Hello?? I am a novice. I have a Nvidia board Jetson nano B01 4GB. I want to debug my kernel driver with qemu. But I encountered a problem using QEMU. After installing qemu, I execute sudo qemu-system-aarch64- machine virt - cpu cortex-a57- geography - smp 4- m 2048- kernel/home/yhai/kernel-4.9/arch64/boot/zImage - initrd/home/yhai/initrd - append "quiet root=/dev/sdc1 rw rootwait rootfstype=ext4" - drive file=/dev/sdc, format=raw, and the Linux kernel has boot information, but the root file system cannot be mounted later. I tried different commands and changed parameters, but all failed. I feel very confused. I suspect that my parameter settings were incorrect, or that there were some areas that were not selected during kernel compilation, but I don't know exactly where the error was.Could you please help me see what's going on? I have used two commands, and I have attached these two commands and the execution results to you. By the way, I am using Ubuntu, version 20.04.My QEMU version is 6.2.92. The Linux kernel is the BSP package kernel of Nvidia's Jetson nano. The version is 4.9.253. Thank you!
