Now you are ready to explore the raspberry pi without actually needing one. In this menu, you can “Expand filesystem” to make use of the increased image size (need to reboot afterwards). The last thing we need to do to get our virtual Raspberry Pi up and running is: pi$ sudo ln -snf mmcblk0p2 /dev/root Now we can stop the emulator and make one final change, the image file is a bit small and we need to increase the size before we continue: osx$ qemu-img resize -wheezy-raspbian.img +8Gįrom now on we can do a normal boot (save this command) by removing the “init=/bin/bash” part: osx$ qemu-system-arm -cpu arm1176 -m 256 -M versatilepb -no-reboot -serial stdio -append "root=/dev/sda2 panic=1 rootfstype=ext4 rw" -kernel kernel-qemu -hda -wheezy-raspbian.img Now create the following file: pi$ vi /etc/udev/rules.d/lesĪnd put in the following content: les KERNEL="sda", SYMLINK+="mmcblk0" We need to add a comment to this file: pi$ vi /etc/ld.so.preloadĬomment this line by placing a # in front of the line: #/usr/lib/arm-linux-gnueabihf/libcofi_rpi.so This is because we need to make two changes to the system: This first boot is a bit special because we only initialize /bin/bash. Now it is time to start the image in the emulator: osx$ qemu-system-arm -cpu arm1176 -m 256 -M versatilepb -no-reboot -serial stdio -append "root=/dev/sda2 panic=1 rootfstype=ext4 rw init=/bin/bash" -kernel kernel-qemu -hda -wheezy-raspbian.img In our case: -wheezy-raspbian.img First boot Now we’ve downloaded the latest version of the raspbian image. Use the following file to get the working version 1.7.1 (other versions had SCSI problems): qemu.rb require 'formula' I’m using the osx$ prefix for commands that are executed on your OS X machine, pi$ for commands on the virtual Raspberry Pi.
Now we need to modify the Homebrew formula (which downloads and install qemu) to the correct version: osx$ vi /usr/local/Library/Formula/qemu.rb
This dongle this is a DVB-T USB stick, but can be turned into full software defined radio. This can than be combined with the amazing RTL-SDR dongle. Today a colleague and I wanted to install gnuradio on a Raspberry Pi. But if you really want speed you’ll have to set up a cross compiler environment or try this other cross compiler setup.Īlso: Links in the article below seem to be broken and it might not work anymore. There is a slightly faster method involving chroot. : 0 comments Raspberry Pi emulation on OS X Disclaimer/spoiler:īuilding for a Raspberry Pi in an emulator is just as slow as on the actual Pi.
