| Supported Features |
| ================== |
| |
| .. zephyr:board-supported-hw:: |
| |
| Programming and Debugging |
| ************************* |
| |
| Applications for the ``rzg2ul_smarc`` board can be built in the usual way as |
| documented in :ref:`build_an_application`. |
| |
| Console |
| ======= |
| |
| By default, `J-Link RTT Viewer`_ is used by Zephyr running on CM33 for providing serial console. |
| The only serial port (SER3_UART micro-USB) is reserved for CA55 to run Linux. |
| |
| .. note:: |
| |
| Set SW1-1 on the board to "OFF" to select JTAG debug mode, which is required for |
| RTT to work. |
| |
| There are two ways to use the RTT Viewer on this board. The basic steps for each method are |
| described below: |
| |
| 1. Using with Ozone |
| ------------------- |
| |
| After the Zephyr application has been built successfully, open J-Link RTT Viewer and configure the |
| connection as follows: |
| |
| - **Connect to J-Link**: Existing Session (enable Auto Reconnect) |
| - **RTT Control Block**: Auto Detection |
| - Click **OK** |
| |
| Next, open `Ozone Debugger`_ and choose "Create New Project". Inside the "New Project Wizard" |
| configure the settings as follows: |
| |
| - **Device**: R9A07G043U11 |
| - **Register Set**: Cortex-M33 |
| - Click **Next** |
| - **Target Interface**: SWD |
| - **Target Interface Speed**: 4MHz |
| - **Host Interface**: USB |
| - Click **Next** |
| - Set the full path of ``zephyr.elf`` file. The path should resemble ``zephyrproject/zephyr/build/zephyr/zephyr.elf`` |
| - Click **Next**, leave all options by default, and click **Finish** |
| - Press **F5** to download and reset program |
| |
| 2. Using with U-Boot |
| -------------------- |
| |
| After the Zephyr application has been built successfully, open the ``zephyr.map`` file located in |
| ``zephyrproject\zephyr\build\zephyr\zephyr.map``. Locate the symbol ``_SEGGER_RTT`` and copy its |
| address value in hexadecimal. |
| |
| Then, perform the "Flashing" steps described below to run the Zephyr application using U-Boot. As soon as the |
| application is invoked, open J-Link RTT Viewer and configure the connection as follows: |
| |
| - **Connect to J-Link**: USB |
| - **Specify Target Device**: R9A07G043U11 (enable Force go on connect) |
| - **Target Interface & Speed**: SWD @ 4000 kHz |
| - **RTT Control Block**: Select "Address", then paste the address of the ``_SEGGER_RTT`` symbol copied earlier. |
| - Click **OK** |
| |
| .. note:: |
| |
| When using RTT Viewer with a Zephyr application launched by U-Boot, it is important to connect |
| the RTT Viewer immediately after executing the U-Boot command sequence. This helps avoid losing |
| early log output. |
| |
| Debugging |
| ========= |
| |
| It is possible to load and execute a Zephyr application binary on |
| this board on the Cortex-M33 System Core from |
| the internal SRAM, using ``JLink`` debugger (:ref:`jlink-debug-host-tools`). |
| |
| Here is an example for building and debugging with the :zephyr:code-sample:`hello_world` application. |
| |
| .. zephyr-app-commands:: |
| :zephyr-app: samples/hello_world |
| :board: rzg2ul_smarc/r9a07g043u11gbg/cm33 |
| :goals: build debug |
| |
| Flashing |
| ======== |
| |
| RZ/G2UL-EVKIT is designed to start different systems on different cores. |
| It uses Yocto as the build system to build Linux system and boot loaders |
| to run Zephyr on Cortex-M33 with u-boot. The minimal steps are described below. |
| |
| 1. Follow "2.2 Building Images" of `SMARC EVK of RZ/G2L, RZ/G2LC, RZ/G2UL Linux Start-up Guide`_ to prepare the build environment. |
| |
| 2. At step (4), follow step "2. Download Multi-OS Package" and "3. Add the layer for Multi-OS Package" |
| of "3.2 OpenAMP related stuff Integration for RZ/G2L, RZ/G2LC and RZ/G2UL" of `Release Note for RZ/G Multi-OS Package V2.2.0`_ |
| to add the layer for Multi-OS Package. |
| |
| .. code-block:: console |
| |
| $ cd ~/rzg_vlp_<pkg ver> |
| $ unzip <Multi-OS Dir>/r01an5869ej0220-rzg-multi-os-pkg.zip |
| $ tar zxvf r01an5869ej0220-rzg-multi-os-pkg/meta-rz-features_multi-os_v2.2.0.tar.gz |
| $ bitbake-layers add-layer ../meta-rz-features/meta-rz-multi-os/meta-rzg2l |
| |
| 3. Start the build: |
| |
| .. code-block:: console |
| |
| $ MACHINE=smarc-rzg2ul bitbake core-image-minimal |
| |
| The below necessary artifacts will be located in the build/tmp/deploy/images |
| |
| +---------------+------------------------------------------------------+ |
| | Artifacts | File name | |
| +===============+======================================================+ |
| | Boot loader | bl2_bp-smarc-rzg2ul.srec | |
| | | | |
| | | fip-smarc-rzg2ul.srec | |
| +---------------+------------------------------------------------------+ |
| | Flash Writer | Flash_Writer_SCIF_RZG2UL_SMARC_DDR4_1GB_1PCS.mot | |
| +---------------+------------------------------------------------------+ |
| |
| 4. Follow "4.2 Startup Procedure" of `SMARC EVK of RZ/G2L, RZ/G2LC, RZ/G2UL Linux Start-up Guide`_ for power supply and board setting |
| at SCIF download (SW11[1:4] = OFF, ON, OFF, ON) and (SW1[1:3] = ON, OFF, OFF) |
| |
| 5. Follow "4.3 Download Flash Writer to RAM" of `SMARC EVK of RZ/G2L, RZ/G2LC, RZ/G2UL Linux Start-up Guide`_ to download Flash Writer to RAM |
| |
| 6. Follow "4.4 Write the Bootloader" of `SMARC EVK of RZ/G2L, RZ/G2LC, RZ/G2UL Linux Start-up Guide`_ to write the boot loader |
| to the target board by using Flash Writer. |
| |
| 7. Follow "4.5 Change Back to Normal Boot Mode" with switch setting (SW11[1:4] = OFF, OFF, OFF, ON) and (SW1[1:2] = ON, OFF) |
| |
| 8. Follow "3. Preparing the SD Card" of `SMARC EVK of RZ/G2L, RZ/G2LC, RZ/G2UL Linux Start-up Guide`_ to write files to the microSD Card |
| |
| 9. Copy zephyr.bin file to microSD card |
| |
| 10. Follow "4.4.2 CM33 Sample Program Invocation with u-boot" from the beginning to step 4 of `Release Note for RZ/G Multi-OS Package V2.2.0`_ |
| |
| 11. Execute the commands stated below on the console to start zephyr application with CM33 core. |
| Here, "N" stands for the partition number in which you stored zephyr.bin file. |
| |
| .. code-block:: console |
| |
| Hit any key to stop autoboot: 2 |
| => dcache off |
| => mmc dev 1 |
| => fatload mmc 1:N 0x00010000 zephyr.bin |
| => fatload mmc 1:N 0x40010000 zephyr.bin |
| => cm33 start_normal 0x00010000 0x40010000 |
| => dcache on |
| |
| Troubleshooting |
| =============== |
| |
| By default, the only valid serial port (SER3_UART micro-USB port) controlled by SCIF0 is used by Linux to |
| print Linux console output. Therefore, in order to use it from Zephyr, the Linux console must first be disabled. |
| To do this, run the following command in the Linux console to unbind the SCIF0 driver: |
| |
| .. code-block:: console |
| |
| $ echo 1004b800.serial | tee /sys/bus/platform/drivers/sh-sci/unbind |
| |
| This allows the SCIF0 to be accessed from the Zephyr side in debug mode for providing serial console. |
| Please note that the SCIF0 driver is disabled by default on the Zephyr side to prevent conflicts. |
