LemonIDETM Chapter 4.
LemonIDETM Chapter 5. Using IDE Chapter 5. Using IDE IDE features of LemonIDE will be explained in this chapter. We will create, build and execute a source file named hello.c on Eddy. Procedures for making a firmware image will be outlined. 5.1 LemonIDE Views LemonIDE IDE(Integrated Development Environment) is based on Eclipse and supports C/C++ source editing, cross compile, remote execution, and GUI builder integration.
LemonIDETM Chapter 5. Using IDE Project View Displays project lists included in Workspace. Make View Displays headers, functions, structures and classes of editing source code Edit View Used for source code editing. Composed of multiple tabs for multiple source code edit. Message View Display messages during project buid and LemonIDE supported Target Browers 5.2 Creating & Editing Source Codes Create a new source file or open an existing source file.
LemonIDETM Chapter 5. Using IDE Sample program “hello.c” is shown below to provide a better understanding on use of LemonIDE. #include void sub (int value); int main (int argc, char *argv[]) { sub (1000); return 0; } void sub (int value) { int sum=0, i; for (i=1; i<=value; i++) { sum += i; } printf ("SUM (1 ~ %4d) = %7d\n", value, sum); return; } 5.3 Compile Environment Settings & Build Compile refers to process of compiling and linking source files and making binary image executable for Eddy.
LemonIDETM Chapter 5. Using IDE 5.3.1 Creating & Updating Makefile If new source file is created or an existing source file in Project View has been altered, a makefile to compile source file must be created. Makefile provide in DK Source can be reference to create a new makefile. Below displays an example of creating a compile environment for makefile for source file, “hello.c” in “src” project, under “Eddy_APPs”folder.
LemonIDETM Chapter 5. Using IDE 5.3.2 Adding to Make Target , If source file and makefile are created, next step is to add makefile to Make Target. Make Target pane can be found in Make View. Select folder where source file and makefile exists, right click and select “Add Make Target”. As new source file “Hello.c”was created on “5.2 Creating & Editing Source Codes”and compile environment on “Hello.c “ was made on “5.3.1 Creating & Updating Makefile”, add compile environment as shown below.
LemonIDETM Chapter 5. Using IDE 5.3.3 Source Compile Source file is compiled to Eddy executable binary file. Compile is carried out by clicking Make Target created in “5.3.2 Adding to Make Target”. (Double click “Hello” on “MakeView”) Compiling process can be observed in “Console” of “Message View”. Make Targets provided in DK Source are “All” and “Clean”. “All” Make Target compiles all application sources associated to makefile, and “Clean” Make Target initializes all compiled applications.
LemonIDETM Chapter 5. Using IDE 5.4.1 Registering Method name and binary file Select “Main” tab and add name & path for executable binary file. Name : Method’s alias Project : The name of the project which binary file is located C/C++ Application : Binary file to be executed As shown in the image above, folder under the project directory may be added with executable binary file name (“Eddy_Apps/hello”), or “Browse” may be used to add its absolute path (“C:\eddy_DK_2xx\src\Eddy_APPs\hello”). 5.4.
LemonIDETM Chapter 5. Using IDE 5.4.4 Configuring Debugger Select “Debugger” tab and add debugger to be used. Debugger : Select debugger type. Select “Esto GDB Server”for LemonIDE Windows and “LemonIDE GDB Server”for LemonIDE Linux. GDB Debugger : Assign path of the selected debugger execution file. Select “c:\cygwin\opt\lemoix\lib\arm-linux-estogdb.
LemonIDETM Chapter 5. Using IDE 5.4.5 Configuring Common Select “Common” tab and check Debug and Run checkboxes to display Debug and Run result information. Normally both Debug and Run options are checked for full display of information. After configuring all options on “Hello” method, click “Close” to finish registor. 5.4.
LemonIDETM Chapter 5. Using IDE 5.5 Executing Run Method Procedures for uploading executable(built) binary files and its executing on Eddy will be introduced in this section. There are two ways to upload & execute binary file on Eddy. One is through LemonIDE’s GDB Server where upload, execution and debug processes can all be carried out automatically. Another way would be to upload the binary file using FTP and manually executing and debugging the binary file through Telnet.
LemonIDETM Chapter 5. Using IDE 5.5.2 Executing Run Method (with results to Serial Port) By default, Eddy’s Target Agent prints out its results through Eddy’s serial console port. Therefore, in order to verify the results printed out to Eddy’s serial console port, a serial communication emulator program is required. Steps on “5.5.1 Configuring Eddy’s Target Agent” must be followed first for this method.
LemonIDETM Chapter 5. Using IDE Click on the icon left to execute last executed Run Method. Clicking on the arrow would allow you to select a Run Method of your listing. The image below shows the result of executing hello.c (of 5.2 Creating & Editing Source Codes) from Telnet.
LemonIDETM Chapter 5. Using IDE 5.6 Creating a Firmware Image Application program which has been compiled and executed on the target (with the instructions of previous chapters) will now be made into a firmware image to be loaded to the target. This chapter will outline the process of creating a firmware image and loading it to its target. 5.6.1 Changing Makefile Changes to Makefile will be made to make a firmware image.
LemonIDETM Chapter 5. Using IDE install: #@echo "Making ramdisk image..." #$(TOOL) -b 8192 -d root -D device_table.txt ramdisk #../tool/genext2fs -U -b 5110 -d root -D device_table.txt ramdisk #../tool/genext2fs -U -b 7158 -d root -D device_table.txt ramdisk #../tool/mkcramfs -q -D device_table.txt root ramdisk ../tool/genext2fs.exe -U -b 10240 -d root -D device_table.txt ramdisk Æ Set Ramdisk size to 10,240K and refer to Device_table.txt to enlist device in Eddy/dev. gzip -vf9 ramdisk test -f ramdisk.
LemonIDETM Chapter 5. Using IDE 5.6.2 Adding to Make Target After creating/changing Makefile for firmware image, it must be added to Make Target. Make Target can be found in Make View pane on right side of LemonIDE. Select Ramdisk project and right click and select “Add Make Target”. cfg, release and install in DK source is already added to Make Target and need not be added again. Refer to “5.3.2 Adding to Make Target” for details on adding procedures to Make Target.
