Create a single firmware build based on CCGx Host SDK v3.2.1 example project

[ShifangZ_26]

1. New created CCGx project based on example code. (Use CCGx Host SDK, since the CCGx project in the Host SDK have includes i2c-boot project.)

• File >> New >> Project…
• Select project type >> Target kit: EZ-PD CCGx HOST SDK (CCG3)

• Select project template >> Code example

• Select a code example >> CYPD3125-40LQXI_notebook

• Create Project>> name workspace/specify location/name project name.

• Add i2c_boot project into workspace: right click “Workspace”, select Add>> Existing Project…

2. Boot-loader Project Changes.

• Open TopDesign.cysch of i2-boot project. And then double click Bootloader_1 component to Make sure that the “Dual-application bootloader” option is unchecked.

• Open config.h file from i2c-boot project head files. Enable define CCG_DUALAPP_DISABLE (CCG_DUALAPP_DISABLE is set as 0u for dual images by default.)

• Compile the project to generate the customized single bootloader binary (.hex & .elf).

3. Application Project Changes (notebook example).

• Pre-build CYPD3125-40LQXI_notebook. cyprj project and generate all relates files.
• Open the CYPD3125-40LQXI_notebook. cyprj project using PSoC Creator 4.2 (the latest version). Double click Bootloadable_1 component and updates the. hex file and .elf file from above process.

• Update Project -> Build Settings -> Debug -> Debug Target from Application Code and Data 2 to Application Code and Data.

• Update linker script for single image build.

• Open the “Project -> Build Settings -> ARM GCC -> User Commands” section and add the following pre-build command.

cmd /c "copy .\Bootloader\CYPD3125-40LQXI_i2c_boot_1_0_3_461_0_0_0_nb.c Generated_Source\PSoC4\cybootloader.c & copy .\Bootloader\CYPD3125-40LQXI_i2c_boot_1_0_3_461_0_0_0_nb.icf Generated_Source\PSoC4\cybootloader.icf"

-----------------------------------------Make sure first step was completed----------------------------------------------

• Build All project

Thanks for creating and posting a detailed Step by Step example.

Step by step examples are helpful.

Please update this example to clarify where the i2c_boot project comes from

Bottom of step 2; after "right click “Workspace”, select Add>> Existing Project…", PSoC Creator 4.3 opens a file explorer window in the project directory on my PC. If I need to first create an i2c_boot project, where does it come from?

If I need to create a Boot Code Example first, please explain or add a link. I was able to find are associated with PSoC 6 such as CE213903 and CE221984.

Again, I really appreciate step by step instructions and I understand there are some steps that become intuitive and aren't described in detail. Unfortunately, some of those intuitive steps aren't intuitive for everyone.

Thanks for your support.
