| .. _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" |
