The standard TI351 software release uses a World Wide (WW) configuration that is compliant in all countries supported by the TI351. See the regulatory release notes for a list of supported countries. Configurations optimized for use in specific countries are available from Ezurio upon request.

Regulatory compliance testing should use the optimized country specific values instead of the WW configuration. This ensures that the product has been validated with the fully optmized values that could be used in a future update. The regulatory package contains optimized country specific configurations for use in regulatory testing only. These files are copied to the firmware directory during installation. These optimized configurations should not be used in end product images.

The optimized country specific configuration file must be manually selected in place of the WW configuration file during testing. The cc33xx-conf.bin symbolic link in the ti-connectivity firmware directory points to the configuration file to be used. Whichever file this link points to when the driver loads is the one used.

Note: If you have worked with Ezurio to use a production level optimized country configuration you do not need to perform this step. Use the optimized country configuration file already on your product.

See the following for an example of changing the configuration file link:

cd /lib/firmware/ti-connectivity
ln -sf cc33xx-conf_US.bin cc33xx-conf.bin

Reboot the device and then perform testing.

Note that the link must be changed back to cc33xx-conf_WW.bin after testing is complete.
