You haven't specified a CPU type, and virt defaults
to cortex-a15. Try "-cpu cortex-a57".

You haven't specified a memory size, and QEMU defaults
to 128MB, which (given the start address of RAM) means
there won't be any RAM at the load address you're trying to
load your test program at. Try "-m 3G", and/or make your
ELF file load at an address closer to the start of RAM.
