If pixman is missing when the following prompt appears, configure –target-list=arm-softmmu –audio-drv-list= In order to prevent the files from being messy after compilation, create the builder directory as the intermediate target path for compilation.ĥ.3 Configure QEMU to support all boards under the arm architecture # apt install libglib2.0-0 libglib2.0-dev * cd qemu-4.2.0 5.2 Install dependent packages before configuring QEMU If running menuconfig shows that the ncurses package is missing, just run the following command to install it)Įnter the menu configuration and make the following settingsĪfter successful compilation, Generate a kernel image file under the directoryĪrch/arm/boot, zImage and dtb can be copied into a separate folder for convenient use Make CROSS_COMPILE=arm-linux-gnueabi- ARCH=arm menuconfig

The host processor is the one running the emulator, and the target processor is what’s being emulated. QEMU takes the approach of providing a minimal translation layer between the host and target processor. It’s available for Linux and Windows hosts and emulated PowerPC, ARM, MIPS, and SPARC targets. Emulating Embedded Linux Systems with QEMUĮmbedded software development relies on embedded hardware devices, such as development boards, external module devices, etc., but if the debugging work has nothing to do with peripherals, only the kernel debugging can be simulated using QEMU without purchasing hardware.
