1+.. _RX-System-emulator:
2+
3+RX System emulator
4+--------------------
5+
6+Use the executable ``qemu-system-rx`` to simulate a Virtual RX target.
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
18+
19+Example of ``qemu-system-rx`` usage for RX is shown below:
20+
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 -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 -kernel <kernel_image_file> -dtb <device_tree_blob> \
35+ -append "earlycon"
