Note: The steps on this page show screen shots and description based on Windows. However the steps in Linux would remain the same, unless mentioned otherwise.; In Linux, use make instead of gmake; The screen shots shown on this page are for AM64x MCU+ SDK v7.3.0. You would see your specific SOC and SDK version that is installed. However the instructions and steps mentioned remain the same, unless mentioned otherwise.

Introduction

All the SDK examples can be configured using a GUI tool called SysConfig. Users can choose and configure various modules using this tool. The SysConfig tool will generate the boilerplate code for initializing these modules. Each example will have an example.syscfg file to which the configuration will be saved to. When creating an example for the first time, this can be an empty file.

SysConfig Features used in the SDK

In this SDK, SysConfig is used to:

Generate configurations for driver modules, board modules and networking modules
Generate clock and power configurations
Generate pinmux for various peripherals

Opening SysConfig GUI from command line and makefiles

For example, if you wanted to configure the dpl hello_world example for r5fss0-0 from the command line, you can run the below commands to do so:
cd ${SDK_INSTALL_PATH}

gmake -s -C examples/hello_world/{board}/r5fss0-0_freertos/ti-arm-clang syscfg-gui
Running the command should open a GUI like below:

Using the SysConfig GUI

The SysConfig GUI is majorly divided into three parts
- A left column (this is hideable) shows a list of modules which can be selected from
- A main column shows the description and various configurable parameters available with the selected module
- A right column showing the generated files (this is also hideable)

SysConfig GUI Columns

If you are seeing only left and main column and right column (generated files) is hidden. You can unhide it by clicking on "<>" menu on main column. Below is snapshot to do this when SysConfig is launched in CCS.

SysConfig GUI Columns

To add an instance of a module, click the (+) sign next to the module name in the left pane. Alternatively, once the module is clicked, a greyed out details show up on the main right column along with an "ADD(+)" button. This can also be clicked to add an instance of a module. You can add more than one instance of a module if that is permitted for the module in the same way

Adding module instance from left column

Adding module instance from main column

Once a module instance is added, you can configure the various attributes shown. If multiple instances are permitted for a module, there will be a "Name" attribute which will be needed later in the application code to identify and distinguish between module instances.

Name Attribute
While configuring the instance using the attributes shown, the C code which corresponds to the configurations is generated in real time. You can see the file list on the right most column, and clicking on a file will open it in the right column.

Files generated by SysConfig

Generated file contents

You can also use the SysConfig GUI to select the PINMUX for a particular module. There will be a default pinmuxing scheme chosen when you add a module, but you can change this according to your needs.

Pinmux in SysConfig

Once all the changes has been done, you can choose File->Save or Ctrl-S if the GUI was invoked from the command line or simply save the example.syscfg file if opened via CCS.
The files are generated using SysConfig whenever we build the example using command line and makefiles.
- Run the following command from command line to generate the the example files:
  - make -sj -C <path_to_the _example> syscfg
  - For example make -sj -C examples/hello_world/j722s-evm/main-r5fss0-0_freertos/ti-arm-clang/ syscfg

Understanding Generated Files

Generated file	Description
ti_dpl_config.c	Source file containing the configurations of various DPL modules like the AddrTranslate, MPU, Clock, Timer etc. This will also contain definitions of Dpl_init() and Dpl_deinit() functions
ti_dpl_config.h	Header file containing declarations of Dpl_init() and Dpl_deinit() functions. This will also include the dpl interface header file, so that the application need not explicitly include that
ti_drivers_config.c	Source file containing the configurations of various driver modules like UART, I2C, OSPI etc. This will also contain definitions of System_init() and System_deinit() functions. These functions will internally call init and deinit functions of respective drivers
ti_drivers_config.h	Header file containing definitions of various macros related to the configuration of driver modules and declarations of System_init() and System_deinit() functions. This will also include the interface header files for the driver modules applicable, so that the application need not explicitly include that
ti_drivers_open_close.c	Source file containing the open parameters of various driver modules like UART, I2C, OSPI etc. This will also contain definitions of Drivers_open() and Drivers_close() functions. These functions will internally call open and close functions of respective drivers. This file will also have the definitions of the handles of respective driver modules
ti_drivers_open_close.h	Header file containing externs of handles and open params related to the configuration of driver modules and declarations of Drivers_open() and Drivers_close() functions
ti_pinmux_config.c	Source file containing pinmux configuration data structures
ti_power_clock_config.c	Source file containing power and clock configuration data for all the modules in the example and definition of PowerClock_init() and PowerClock_deinit() functions and other internal functions required to configure power and clock for the modules
ti_board_config.c	Source file containing the configurations of various board modules like Flash, EEPROM, LED etc. This will also contain definitions of Board_init() and Board_deinit() functions. These functions will internally call init and deinit functions of respective board modules
ti_board_config.h	Header file containing definitions of varios macros related to configurations of various board modules and declarations of Board_init() and Board_deinit() functions
ti_board_open_close.c	Source file containing the open parameters of various board modules like Flash, EEPROM, LED etc. This will also contain definitions of Board_driversOpen() and Board_driversClose() functions. These functions will internally call open and close functions of respective modules. This file will also have the definitions of the handles of respective board modules
ti_board_open_close.h	Header file containing externs of handles and open params related to the configuration of board modules and declarations of Board_driversOpen() and Board_driversClose() functions
example.syscfg	Configuration file to which all the changes made in the GUI is saved

Tips and Tricks for SysConfig

Changes made on SysConfig GUI will be saved in the example.syscfg file. If you need to quickly check what was the value configured for some parameter, you can open this file in an editor instead of opening the GUI.
