| 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> \ |
| 36 | -append "earlycon" |
