Supported color depths

The reference port for this board supports 16bpp color depth.

PSRAM support

You can enable Qt Quick Ultralite to initialize and use PSRAM for asset preloading by doing one of the following:

• Add QUL_PLATFORM_PRIVATE_ENABLE_PSRAM compiler definition to the ModusToolbox CM55 project.
• Open proj_cm55/QtMCUs/platform/boards/cypress/psoc-edge-e84-freertos/platform_config.h in the ModusToolbox project and modify it to have the following:

  #ifndef QUL_PLATFORM_PRIVATE_ENABLE_PSRAM
  // Initialize and enable external PSRAM memory.
  #define QUL_PLATFORM_PRIVATE_ENABLE_PSRAM
  #endif

• Rebuild the platform library with -DQUL_PLATFORM_PRIVATE_ENABLE_PSRAM CMake flag. For more information on how to build the platform library, see building Qt Quick Ultralite from sources.

You can also modify the PSRAM size Qt Quick Ultralite can use by changing the value of QUL_PLATFORM_PRIVATE_PSRAM_SIZE definition in proj_cm55/QtMCUs/platform/boards/cypress/psoc-edge-e84-freertos/platform_config.h. Changing the value has no effect if QUL_PLATFORM_PRIVATE_ENABLE_PSRAM is not defined.

LLVM support

You can enable the LLVM support by building the Qt Quick Ultralite libraries using the LLVM toolchain. Follow the instructions in Building Qt Quick Ultralite from sources topic and use the following values in the CMake configuration phase:

-DCMAKE_TOOLCHAIN_FILE=$QUL_ROOT/lib/cmake/Qul/toolchain/llvm-arm.cmake \
-DQUL_TARGET_TOOLCHAIN_DIR=/path/to/LLVM-ET-Arm-19.1.5-Linux-x86_64

-DCMAKE_TOOLCHAIN_FILE=%QUL_ROOT%\lib\cmake\Qul\toolchain\llvm-arm.cmake ^
-DQUL_TARGET_TOOLCHAIN_DIR=C:\path\to\LLVM-ET-Arm-19.1.5-Linux-x86_64

After building the Qt Quick Ultralite libraries, you can export a Qt Quick Ultralite application using the built libraries by following the instructions here.
