Emulating Jessie image with 4.x.xx kernel https://github.com/dhruvvyas90/qemu-rpi-kernel/wiki/Emulating-Jessie-image-with-4.x.xx-kernel 2. Change Screen Resolution? https://www.raspberrypi.org/forums/viewtopic.php?f=66&t=136280 3. CONFIG.TXT https://www.raspberrypi.org/documentation/configuration/config-txt/README.md 二、下载内核: https://github.com/dhruvvyas90/qemu-rpi-kernel三、下载树莓派系统: 1. https://downloads.raspberrypi.org/raspbian_lite_latest 2. https://downloads.raspberrypi.org/raspbian_latest四、操作流程: 1. 文件系统修改: 1. fdisk -l <树莓派系统镜像> zengjf@zengjf:~/rpi$ sudo fdisk -l 2017-03-02-raspbian-jessie-lite.img [sudo] password for zengjf: Disk 2017-03-02-raspbian-jessie-lite.img: 1.3 GiB, 1393557504 bytes, 2721792 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disklabel type: dos Disk identifier: 0xb2455b06 Device Boot Start End Sectors Size Id Type 2017-03-02-raspbian-jessie-lite.img1 8192 137215 129024 63M c W95 FAT 2017-03-02-raspbian-jessie-lite.img2 137216 2721791 2584576 1.2G 83 Linux 2. 磁盘偏移计算:137216 * 512 = 70254592 3. mount -v -o offset=70254592 -t ext4 your-image-file.img /mnt 4. cd /mnt 5. sudo vim ./etc/ld.so.preload 注释掉所有的内容就可以了,一般里面只有一行,直接注释掉就OK了。 6. sudo vim ./etc/fstab 看到和/dev/mmcblk有关的都可以注释掉。 7. cd ~ 8. sudo umount /mnt 2. 参考运行命令: 1. lite版参考执行命令 qemu-system-arm -kernel kernel-qemu-4.4.26-jessie -cpu arm1176 -m 256 -M versatilepb -serial stdio -append "root=/dev/sda2 rootfstype=ext4 rw" -hda 2017-03-02-raspbian-jessie-lite.img 2. desktop版参考执行命令 qemu-system-arm -kernel kernel-qemu-4.4.26-jessie -cpu arm1176 -m 256 -M versatilepb -serial stdio -append "root=/dev/sda2 rootfstype=ext4 rw" -hda 2017-04-10-raspbian-jessie.img 树莓派系统镜像>
