Raspberry pi QEMU

Kernel Build Notes

QEMU ARM Emulator

Use the script 'build-kernel-qemu' to build a kernel image that can be used to boot QEMU.

Script will download kernel 4.1.7 sources and toolchain used to compile it. A precompiled kernel version is available with the script

Assumptions

Your system is able to execute 32 bit binaries, and you have git tool

Tests

Tested by booting Raspbian 8 (Jessie) kernel 4.1.7 system in QEMU

You also need to mount raspbian image file and edit /etc/fstab by commenting out mmcblk entries. also on /etc/ld.so.preload you need to comment out all entries

after that, you can boot iamge using qemu:

qemu-system-arm -kernel kernel-qemu -cpu arm1176 -m 256 -M versatilepb -hda 2015-09-24-raspbian-jessie.img -append "root=/dev/sda2 rootfstype=ext4"

raspberry-qemu's Issues

qemu returns a black screen emulating on a raspberry pi 2 (rasbian)

I used the kernel in your repo kernel-qemu . nothing returned but a black window by qemu.

here's the log

WARNING: Image format was not specified for '/path/to/pi2-16gb.img' and probing guessed raw.
        Automatically detecting the format is dangerous for raw images, write operations on block 0 will be restricted.
        Specify the 'raw' format explicitly to remove the restrictions.

It even didn't try to uncompress the kernel...

Here's the full issue for this scenario.

Thank you a million if you can help!
