Qemu-system-arm-M vexpress-a9-serial stdio-kernel u-boot-sd rootfs ext-nographicOptions:
  1. Yes it’s perfectly fine, it should run u-boot
  2. No the kernel image is not provided, so it will crash
  3. No the rootfs image has ext format, so this shoudn’t
  4. Looks like some other issue which is not mentioned here
