   6 Use the executable ``qemu-system-rx`` to simulate RX target (GDB simulator).
   7 This target emulated following devices.
   8
   9 -  R5F562N8 MCU
  10
  11    -  On-chip memory (ROM 512KB, RAM 96KB)
  12    -  Interrupt Control Unit (ICUa)
  13    -  8Bit Timer x 1CH (TMR0,1)
  14    -  Compare Match Timer x 2CH (CMT0,1)
  15    -  Serial Communication Interface x 1CH (SCI0)
  16
  17 -  External memory 16MByte

  21 Download ``<u-boot_image_file>`` from
  22 https://osdn.net/users/ysato/pf/qemu/dl/u-boot.bin.gz
  23
  24 Start emulation of rx-virt::
  25   qemu-system-rx -M gdbsim-r5f562n8 -bios <u-boot_image_file>
  26
  27 Download ``kernel_image_file`` from
  28 https://osdn.net/users/ysato/pf/qemu/dl/zImage
  29
  30 Download ``device_tree_blob`` from
  31 https://osdn.net/users/ysato/pf/qemu/dl/rx-virt.dtb
  32
  33 Start emulation of rx-virt::
  34   qemu-system-rx -M gdbsim-r5f562n8 \
  35       -kernel <kernel_image_file> -dtb <device_tree_blob> \
  36       -append "earlycon"
