Target setup for RZA1H
This document describes the setup required to build and run CGI Studio applications with RZA1H device package on Renesas RZA1H hardware.It is explained how to run the RZA1H target demo application part of the release package, how to setup the build environment and how to build own applications for RZA1H target (Renesas RZA1H).

RZA1H BSP

Prerequisites
Hardware: Renesas RZA1H 
 CGI Studio has been tested on Renesas RZA1H custom board. 
 CMake 
 In order to build Candera, the Meta build system CMake needs to be installed with at least version mentioned here . 
 CMake is able to create the cross compilation make files that can be used with various compilers. 
 Ninja 
 To allow cross compilation with makefiles, MinGW 4.2.1 (Ninja 1.9.0) was used for this release. 
 GCC Toolchain 
 The build tool chain is not part of the delivery. gcc-arm-none-eabi-9-2020-q2-update-win32.exe and the according Renesas BSP and RGL driver have to be obtained from customer and installed according to their installation guide. 
 CGI Studio was tested with gcc-arm-none-eabi-9-2020-q2-update-win32.exe 
 Debugging was done over J-LINK 10.1 in Renesas e² studio. 
 Renesas RGA Library 
 The graphics driver is not part of this release. CGI Studio was integrated and tested with the libraries received from customer

Running the CGI CourierSampleAppLight Demo Application on RZA1H
Download the Application 
 To download and debug the application you need Renesas e 2 Studio, a sample project and a J-Link probe. 
 Include "cgi_studio_courier_apps\src\CourierSampleAppLight\AppPlatform\Target_FreeRTOS_ARM\SampleAppConnector.h" in the main.c og the sample application. Declare extern function SwapRequiredBuffers  "extern void SwapRequiredBuffers();" Initialize the App with SampleAppInit(); In a loop call SampleAppRun(); and SwapRequiredBuffers(); 
 Start SEGGER J-Flash lite and download the asset file to the address defined in linker_settings.ld as __graphics_data_start. 
 Compile the project and use Renesas e 2 Studio to download and debug the binary to the target.　

Building Own Application for the RZA1H
Generate Makefiles with CMake 
 For general information about CGI Studio Build System and CMake properties available to configure Candera applications refer to CGI Studio Build System . 
 To configure and generate makefiles for compiling the CGI CourierSampleAppLight, follow below steps: 
 
 
 
 
 Point CMake to source directory
 
 Folder containing top-level "CMakeLists.txt", e.g.
 /cmake/Apps/Courier/CourierSampleAppLight
 
 
 
 
 Point CMake to build directory
 
 May not exist, create folder with CMake if necessary 
 Root directory for generated makefiles / solutions 
 Root directory for build artifacts 
 
 
 Configure
 
 Specify MinGW Makefiles (Ninja) as generator for the project 
 Specify tool-chain file for cross-compiling 
 
 
 Select the toolchain-file from the delivery (adapt for your toolchain installation and application specific needs)
 /cgi_studio_devices/src/RZA1H/ToolchainFiles/GCC-toolchain-RZA1H_Native2D.txt
 
   
 
 Adapt the CMake settings if necessary, e.g.:
 
 CMAKE_BUILD_TYPE-> Debug or Release 
 Press Configure 
 
 
 
 Press Generate 
 
 
 
 
 
 Building Application 
 After generating your cmake files, in Command Prompt simply navigate to the specified build directory and type "mingw32-make" ("ninja") to start the build. 
 The output executable file can be found in your build directory. 
 Open this file with the Green Hills MULTI IDE debugger and load it to RAM as described in the previous chapter.

Various Device Specific Content

RZA1HBitmapConverter
Description 
 This document provides a complete list of bitmap formats supported by the RZA1H Target. 
 These formats define how pixel color and alpha data are stored in memory. The RZA1H extended bitmap formats support alpha-only , RGB , ARGB , and JPEG compressed images formats to address different memory, performance, and visual quality requirements. 
 These bitmap converters are supported only on the target. Windows simulation uses the default bitmap converter. 
 Alpha Only Formats 
 Alpha formats (A1/A4/A8) are primarily used for masking and blending operations.
