The Renesas EK-RZ/A3M board is an evaluation kit for the RZ/A3M MPU. It is an MPU but it has a focus on baremetal and RTOS applications. It boasts a mighty 1 GHz Cortex-A55 CPU and 128 MB of DDR3L-SDRAM. It is easy to use the low-level IO, of which it provides a lot. The board offers connectivity to many ecosystems like Arduino, Qwiic, Grove, mikroBUS, and Pmod. A 1280x720 display is included in the kit. It mounts to the board via a board-to-board connector.

- Audio codec with i2s and ADC
- Micro-SD Card slot
- USB host or device
- Two 40 pin native pin headers
- MIPI display connector (connects to included display board)
- Ecosystem connectors (Arduino, Qwiic, Grove, mikroBUS, and Pmod)
- Mount the graphics expansion board to the mainboard. Two of the standoffs on the mainboard should be replaced with shorter ones and then the graphics board can be mounted underneath the mainboard. The shorter standoffs can be secured with the included screws.
- Set all the DIP switches to OFF.
- Connect a USB C cable to DEBUG1 (J10) and your PC.
- Install e2 studio for your OS.
- When prompted, choose "Custom Install".
- Ensure "RZ" is included in your selection of "Device Families" to install.
- Ensure "Renesas FSP Smart Configurator Core" and "Renesas FSP Smart Configurator ARM" are included in your selection of "Customize Features".
- Ensure "GCC ToolChains & Utilities" is selected and "GCC ARM A-Profile (AArch64 bare-metal) 13.2 rel1" under that tab is also selected in "Additional Software".
- Install FSP Packs. It was tested with v3.4.0, which was the latest version at the time.
- On Windows, simply download RZA_FSP_Packs_vX.X.X.exe from here under "Assets" for the desired release. Run the installer and follow the prompts.
- On Linux, download RZA_FSP_Packs_vX.X.X.zip
from here under "Assets" for the desired release.
Locate the e2 studio install location. If it is
~/.local/share/renesas/e2_studioand the ZIP download is~/Downloads/RZA_FSP_Packs_v3.4.0.zip, unzip the file with the following commands:The directory structure of the ZIP structure may overlap with some of the structure of the e2_studio install loction. This is expected. Thecd ~/.local/share/renesas/e2_studio unzip ~/Downloads/RZA_FSP_Packs_v3.4.0.zip
unzipprocess will update the directory structure with the new FSP files from the ZIP and preserve any existing FSP packs. Refer to "2.2.3 Installation of FSP Packs using Package Zip file" in this guide for more details.
- Clone the repository
git clone --recurse-submodules https://github.com/lvgl/lv_port_renesas-ek-rz_a3m.git
- Open e2 studio and go to File > Open Projects from File System.... Click "Directory" and navigate to the cloned project and then click "Finish".
- Click the hammer to build the project. If it is greyed-out, first single-click the project "lv_ek_rza3m" in the left sidebar and the hammer should become clickable.
- To upload and run the project, click the bug (debug) icon. The debugger will break (stop execution) at the beginning. Click the "Resume" button to continue execution.
- In the previous section, the project was run using the debugger. Simply continue using the interactive debugger in e2 studio to debug your program. Set breakpoints, continue, step, etc. as with any other Eclipse-based IDE.
