This page provides information on how to use the SDK for Custom Boards

BSP

Board Specific drivers

The rz_bsp configuration file "mcu_board_select.h" set up both the TARGET_MCU and TARGET_BOARD for the rz_bsp and some on the Azure middleware. This section discuss how to configure the BSP for custom boards.

...

• BOARD Selection

  -The TARGET_BOARD is not required for custom board configuration. This setting is for the middleware( Audio Codec, Phy, Camera modules, LCD) and some drivers ( led, switches, SCI ( TTY), and I2C(touch)). By setting the TARGET_BAORD to 0 these middleware and drivers are disabled.

VDC5 Graphic Drivers

• -The VDC5 configuration files are located tin the rz_bsp .\src\renesas\application\graphics\inc

• lcd_panel.h

  - This configuration file selects what board LCD is supported and number of supported LCD. RZA1H and M support 2 LCD panels or one LVDS all other support one LCD. FOr custom board you an override the number of supported LCDs here.

• .\lcd\rsk_tft_ch0.h

  - Configuration control signals for RZA1H/M VDC5 channel 0.

• .\lcd\rsk_tft_ch1.h

  - Configuration control signals for RZA1H/M VDC5 channel 1.

• .\lcd\rsk_tft_clk.h

  - RZA1H/M VDC5 defines macros for the above signals

• .\lcd\stream2_tft_ch0.h

  - Configuration control signals for RZA1L/LU/LC VDC5 channel 0.

• .\lcd\stream2_tft_clk.h

  - RZA1L/LU/LC VDC5 defines macros for the above signals

GUIX Drivers

The rz_bsp provides three drivers for the 16bpp (RGB565), 24bpp (RBG888), and 32bpp (RGB8888). The rz_bsp mcu configuration file allows for selection of these three drivers. This section shows how create a custom driver.

GUIX Application Port

The GUIX sample projects include a GUIX Studio Project (GXP). This sections describes settings in the GXP project and how to port these changes to a RZA.

USBX Drivers

The USB hardware is the same for all RZA1 parts.

1. Set the MPU board, and GUI Driver( see Renesas RZA1 BSP Board Configuration ).
2. Full Build of the rz_bsp project.
3. In the USBX library set the USB channel. For USB Device open "\common\usbx_device_controllers\ux_dcd_rz.h". For USB Host open "\common\usbx_host_controllers\ux_hcd_rz.h"
4. Set the preprocessor define UX_RZ_USB_BASE to the desired channel. Note: The setting in the file "ux_hcd_rz.h" has condition compilation depending on the board selected, so it may not be required to make additional settings.

   #define UX_RZ_USB0_BASE 0xE8010000#define UX_RZ_USB1_BASE 0xE8207000....#define UX_RZ_USB_BASE UX_RZ_USB0_BASE

5. Rebuild the USBx library. This is required because the RZ USB drivers are part of the USBX library. These drivers have conditional compilations for the selected board ( not MPU).
6. In the USB Sample demo select the build configuration that matches the selection in step 1.
7. Download and Run demo.
