In file mode, the loader accepts a file as data to load. The follo wing subsections describe these modes. Specify only one mode for each -device argument. There are two basic modes for the loader argument: file mode and single transaction mode.

#QEMU SYSTEM C SOFTWARE#

You can use a combination of -device loader arguments to load software and setup the CPUs. In Zynq Ultrascale+ MPSoC, by default, the six ARM CPUs (four ARM- A53 and two ARM-R5) are in reset by their respective reset controllers w hen no software is loaded. Load software or da ta into RAM sections.

#QEMU SYSTEM C DRIVER#

The loader driver can perform the following tasks: This (repeatable) argument confi gures the QEMU machine for boot. If building DTBs from source, the single-arch and multi-arch device trees will appear under path/to/dts-repo/LATEST/SINGLE_ARCH and path/to/dts-repo /LATEST/MULTI_ARCH respectively.

Multi-arch: zynqmp-qemu-multiarch-arm.dtb, zynqmp-qemu-multiarch-pmu.dtb.

The following DTBs are available in PetaLinux project: Zynq UltraScale+ MPSoC QEMU DTS are different for Zynq Ultrascale+ MPSoC and Versal ACAP single and multi-architecture models. This procedure is applicable onl y when -kernel is passed on QEMU command line.įor Zynq Ultrascale+ MPSoC and Versal ACAP in a multi-architecture environment, the QEMU DTB is different from the kernel system.dtb. If both -hw-dtb and -dtb are used in multi-arch environments, the DTB passed in with -dtb is ignored.įor standalone (single-arch) flows, these two arguments are fully interchangeable specify only one or the other. Xilinx Linux kernel device tree binaries are typically named system.dtb.įor booting Linux on multi-arch platforms, such as Zynq Ultrascale+ MPSoC and Versal ACAP, we use the -hw-dtb option, since guest device tree loading is skipped by QEMU. With the DTB passed in with -dtb option, QEMU removes the nodes that it cannot emulate and later copies them to RAM for the kernel.

-dtb is generally a Linux device tree binary used for Linux kernel boots.

For example, board-versal-ps-vc-p-a2197-00.dtb is for Versal and zcu102-arm.dtb for the ZCU102 board. Hardware device tree binaries will have the name of the device it represents.

-hw-dtb is used for the hardware device tree binary that QEMU uses to generate the model.

Xilinx QEMU supports two device tree options:

#QEMU SYSTEM C SERIAL#

serial nullĭon't connect this serial device -serial chardev:pmu-consoleĬonnect this serial device to the chardev pmu-console. Typically this is used with the gdb option to debug the boot sequence of your machine.Ĭonnect this serial device to the QEMU monitor and STDIO. Pauses the machine on the first instruction. Specifies there's no graphics and passes in -serial stdio as well. This machine will have no graphic output. net user,id=eth0,tftp=/host/path/for/tftpĬreates a network back-end with the ID eth0 that has TFTP access to the host path When user is specified, this option configures a host network back-end and connects it to the emulated default hub.Ĭreates an on-board NIC. When nic is specified, this option configures or creates an on-board network interface card and connects it either to the emulated hub, or to the netdev nd. Specifies that / tmp/qemu-shm is where QEMU shared memory and UNIX sockets will be created. PetaLinux and Yocto tools do this for you. It is recommended you clear the -machine-path directory between boots. Specifies that this is a microblaze-fdt machine. Specifies that this is an ARM-generic-fdt machine. This machine will have 512MB of RAM allocated This machine will have 4GB of RAM allocated -m 512M Specifies the image pmu_rom_qemu_sha3.elf.Īllocates memory size bytes of RAM for the virtual machine. kernel /path/to/kernel/pmu_rom_qemu_sha3.elf Specifies an image, such as a kernel or bare-metal image. Specifies the QEMU hardware description to be zynqmp-qemu-multiarch-arm.dtb. hw-dtb /path/to/dtb/zynqmp-qemu-multiarch-arm.dtb See: -dtb vs -hw-dtb for how this differs from the -dtb parameter. The hardware description for the QEMU machine. Sets driver properties for devices created by the machine model. Speficies the QEMU hardware description to be system.dtb and passes it to the Linux Kernel (if present). If a Linux kernel is present, the dtb is passed to it through a memory buffer. Anything that QEMU cannot emulate is discarded. drive file=/path/to/img/qemu_boot.img,if=sd,format=raw,index=1Ĭreates an SD drive at index 1 with the image qemu_boot.img. When writing data to an address, the order must be addr=,data=,data-len=
