HopeRun HiHope RZ/G2M
The HiHope RZ/G2M (hihope-rzg2m) is manufactured by Jiangsu HopeRun Software Co., Ltd. and uses the Renesas RZ/G2M MPU. More information about the platform can be found on the HiHope RZ/G2M product page.
The HiHope RZ/G2M platform consists of four parts:
- Renesas RZ/G2M (r8a774a1) MPU - HopeRun HiHope RZ/G2M platform - HopeRun expansion board for HiHope RZ/G2 platforms (optional)
From HopeRun:
The HiHope RZ/G2M microprocessor (MPU) features a 64-bit multi-core architecture with advanced graphics capabilities and a high-bandwidth memory interface to support systems with enhanced human-machine interfaces.
More information about the Renesas RZ/G2M MPU can be found on the Renesas website.
Building for the hihope-rzg2m Platform
Instructions on building the CIP SLTS Linux Kernel, the Renesas Yocto BSP and the Renesas SDK for the hihope-rzg2m platform can be found here.
Using the hihope-rzg2m Platform
This section provides information on using this reference platform.
The instructions assume that you are using the optional expansion board. If you are not, please use change the device tree you use accordingly:
| Device Tree Blob | Platform Makeup |
|---|---|
| r8a774a1-hihope-rzg2m.dtb | r8a774a1 hihope-rzg2m |
| r8a774a1-hihope-rzg2m-ex.dtb | r8a774a1 hihope-rzg2m hihope-rzg2-ex |
Switch Settings
On the hihope-rzg2m there are three sets of switches - SW1001, SW1002 and SW1003 (BOOT CONFIG SW).
Default switch positions for SPI Flash boot are as follows:
| SW Bits | SW1001 | SW1002 | SW1003 |
|---|---|---|---|
| 1 | OFF | ON | OFF |
| 2 | ON | ON | ON |
| 3 | ON | ON | ON |
| 4 | ON | ON | ON |
| 5 | ON | ON | ON |
| 6 | ON | OFF | ON |
| 7 | ON | ON | ON |
| 8 | ON | ON | ON |
Connect to the board

Power Supply
Use the 12V power supply that comes with the platform and connect it to J2401 (POWER JACK).
Serial Console
Use a microUSB cable to connect the host PC to the hihope-rzg2m, using CN2201 (DEBUG PORT). It is routed to SCIF2 on the RZ/G2M via UART to USB convertor CP2102.
Virtual COM port (VCP) Windows drivers are available from the Silicon Labs website. Unless using a very old Linux distribution, CP210x should be supported.
Serial settings:
- Baud rate: 115200
- Data: 8 bit
- Parity: None
- Stop: 1 bit
- Flow control: None
Any standard terminal emulator program can be used.
Notes
J8 (SATA connector) on the expansion board is not supported on hihope-rzg2m because of RZ/G2M specification. This is reserved for other MPU.
Booting the Kernel
To boot the board, flip SW2402 (next to DC Jack) to the 'ON' position (1-pin side, outside of the board). The following bootloader output should be seen on the debug serial console:
