Example of @file{qemu-system-mipsel} usage for nanoMIPS is shown below:



Download @code{<disk_image_file>} from @url{https://mipsdistros.mips.com/LinuxDistro/nanomips/buildroot/index.html}.

Start system emulation of Malta board with nanoMIPS I7200 CPU:

@example

qemu-system-mipsel -cpu I7200 -kernel @code{<kernel_image_file>} \

    -M malta -serial stdio -m @code{<memory_size>} -hda @code{<disk_image_file>} \
