4 SysConfig Tool

TI provides an offline resource management tool called SysConfig. SysConfig can be used to auto generate generic code that can then be used in the SDK for programming of firewalls. General usage for the firewalls would be as listed below:

  1. Use the TI SysConfig tool to define the various firewalls that are to be programmed
  2. The SysConfig tool will generate a .c file.
  3. Integrate the contents from the autogenerated .c file into the boot flow of choice

For instructions on installing and using the SysConfig, reference the embedded link.

The output format from SysConfig can be re-used in the sample code included in this document.
