- .. _RX-System-emulator:
- RX System emulator
- --------------------
- Use the executable ``qemu-system-rx`` to simulate RX target (GDB simulator).
- This target emulated following devices.
- - R5F562N8 MCU
- - On-chip memory (ROM 512KB, RAM 96KB)
- - Interrupt Control Unit (ICUa)
- - 8Bit Timer x 1CH (TMR0,1)
- - Compare Match Timer x 2CH (CMT0,1)
- - Serial Communication Interface x 1CH (SCI0)
- - External memory 16MByte
- Example of ``qemu-system-rx`` usage for RX is shown below:
- Download ``<u-boot_image_file>`` from
- https://osdn.net/users/ysato/pf/qemu/dl/u-boot.bin.gz
- Start emulation of rx-virt::
- qemu-system-rx -M gdbsim-r5f562n8 -bios <u-boot_image_file>
- Download ``kernel_image_file`` from
- https://osdn.net/users/ysato/pf/qemu/dl/zImage
- Download ``device_tree_blob`` from
- https://osdn.net/users/ysato/pf/qemu/dl/rx-virt.dtb
- Start emulation of rx-virt::
- qemu-system-rx -M gdbsim-r5f562n8 \
- -kernel <kernel_image_file> -dtb <device_tree_blob> \
- -append "earlycon"
