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:
- Open 2 terminals in my host PC (Ubuntu 20.04)
- Use the command to run QEMU in first terminal:
$ qemu-system-aarch64 \Output as below
-smp 8 \
-machine type=virt,gic-version=3 \

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.
