1 | .. _RX-System-emulator: |
| 2 | ||
| 3 | RX System emulator | |
| 4 | -------------------- | |
| 5 | ||
| 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 | |
| 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 -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> \ | |
