推荐答案

您没有控制台。使用'-append控制台= tty1上，如下图所示。追加提供命令行参数的内核。同时，控制台问题被固定后，你可能会看到需要一个根文件系统;许多选项存在那里，我用的是previously安装的磁盘映像，我已经展示了一个命令行既之下。

You have no console. Use '-append "console=tty1"' as shown below. Append gives command line arguments to kernel. Also, after the console issue is fixed, you will probably see a need for a root filesystem; many options exist there, I use a previously-mounted disk image, I have shown a commandline with both below.

qemu-system-arm -M versatilepb -m 128M -kernel /home/<name>/linux-3.10.10/arch/arm/boot/uImage -append "console=tty1 root=/dev/mmcblk0p1 rootfstype=ext3" -drive file=disk.img,if=sd
