The command for the QEMU boot is as follows:

petalinux-boot --qemu --prebuilt <BOOT_LEVEL>
Note: The QEMU boot does not support BOOT_LEVEL 1.
  • Level 1: Download the prebuilt FPGA bitstream.
    • It boots FSBL and PMU firmware for Zynq® UltraScale+™ MPSoC.
    • It boots FSBL for Zynq-7000 devices.
  • Level 2: Download the prebuilt FPGA bitstream and boot the prebuilt U-Boot.
    • For Zynq-7000 devices: It boots FSBL before booting U-Boot.
    • For Zynq UltraScale+ MPSoC: It boots PMU firmware, FSBL, and TF-A before booting U-Boot.
    • For Versal® devices: It loads the required cdo files from .pdi file, PLM, PSM firmware, and TF-A before booting U-Boot.
  • Level 3: Download and boot till prebuilt Linux
    • For MicroBlaze™ processors: Downloads the prebuilt FPGA bitstream and boots the prebuilt kernel image on target.
    • For Zynq-7000 devices: Downloads the prebuilt FPGA bitstream and FSBL, boots the prebuilt U-Boot, and boots the prebuilt kernel on target.
    • For Zynq UltraScale+ MPSoC: Downloads prebuilt FPGA bitstream, prebuilt FSBL, prebuilt PMU firmware, prebuilt TF-A, prebuilt u-boot and prebuilt kernel on target.
    • For Versal devices: It loads the required cdo files from .pdi file, PLM, PSM firmware, TF-A, and U-Boot before booting Kernel.
