试图弄清楚为什么我的Raspberry Pi在Qemu中运行Buster OS时出现空白屏幕,但是具有CLI功能吗?这是我的跑步方式:
$ qemu-system-arm -M versatilepb -cpu arm1176 -m 256 -hda ./raspbian-buster-full.qcow -net nic -net user,hostfwd=tcp::5022-:22 -dtb ./versatile-pb.dtb -kernel ./kernel-qemu-4.19.50-buster -append 'root=/dev/sda2 panic=1 rootfstype=ext4 rw' -no-reboot -serial stdio
最后出现一些失败消息:
vpb_sic_write: Bad register offset 0x2c
...
Welcome to Raspbian GNU/Linux 10 (buster)!
systemd[1]: Set hostname to <raspberrypi>.
systemd-fstab-generator[41]: Mount point file is not a valid path, ignoring.
...
[FAILED] Failed to start Load Kernel Modules.
See 'systemctl status systemd-modules-load.service' for details.
...
[FAILED] Failed to start rng-tools.service.
See 'systemctl status rng-tools.service' for details.
不确定vpb_sic_write: Bad register offset 0x2c
与[FAILED] Failed to start Load Kernel Modules.
有什么关系,但是我对[FAILED] Failed to start rng-tools.service.
表示满意,因为我认为rng-tools
与随机数的产生有关,而我没有不需要。
起初我以为显示不足是由于未在append选项中指定控制台,但在启动脚本中确实看到了以下内容,这使我认为这不是问题。
clocksource: arm,sp804: mask: 0xffffffff max_cycles: 0xffffffff, max_idle_ns: 1911260446275 ns

有什么建议吗?谢谢!
