Qemu显示黑屏

Question

When the run following command on the teriminal

qemu-system-arm -M versatilepb -m 128M -kernel /home/<name>/linux-3.10.10/arch/arm/boot/uImage

A window with black screen will be opened and remain blank with no messages, but I am expecting Kernel messages on this screen. Please suggest a solution.

Answer 1

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

如果您正在尝试模拟Raspberry Pi，请按照Joe Kul的回答中的建议使用，但不要使用tty1而是使用ttyAMA0 。
