I'm buiding images for LS2088ardb by using Yocto command "bitbake fsl-image-networking"

Now I load the dtb in the QEMU but can't boot into kernel and step by step SOP as below:

  1.  Open 2 terminals in my host PC (Ubuntu 20.04)
  2.  Use the command to run QEMU in first terminal:
    $ qemu-system-aarch64 \
        -smp 8 \
        -machine type=virt,gic-version=3 \
        -m 2048 \
        -cpu cortex-a72 \
        -kernel Image \
        -serial tcp::4446,server,telnet \
        -drive if=none,file=fsl-image-networking-ls2088ardb.rootfs-20240711074828.ext4,id=foo,format=raw \
        -device virtio-blk-device,drive=foo \
        -append 'root=/dev/vda rw console=ttyAMA0,115200 rootwait earlyprintk' \
        -monitor stdio
    Output as below
    QEMU 4.2.1 monitor - type 'help' for more information
    (qemu) qemu-system-aarch64: -serial tcp::4446,server,telnet: info: QEMU waiting for connection on: disconnected:telnet:0.0.0.0:4446,server
  3. Use the command to connect QEMU in second terminal:
    telnet 0.0.0.0 4446
    I can success to boot into kernel
    Trying 0.0.0.0...
    Connected to 0.0.0.0.

  4. Trying to use the command to load device tree in first terminal
    $ qemu-system-aarch64 \

You cannot emulate the device in a PC. This would need to create a new QEMU image that works with all the modules of the LS2088A and we do not have any image like that.

 

What I understood was to simulate an Arm OS with QEMU in the board and you can for sure do that.
