Troubleshooting OTA Updates with the Texas Instruments CC3220SF Launchpad

The CC3220SF Launchpad platform provides a software tamper-detection mechanism. It uses a security alert counter that is incremented whenever there is an integrity violation. The device is locked when the security alert counter reaches a predetermined threshold (the default is 15) and the host receives the SL_ERROR_DEVICE_LOCKED_SECURITY_ALERT asynchronous event. The locked device then has limited accessibility. To recover the device, you can reprogram it or use the restore-to-factory process to revert to the factory image. You should program the desired behavior by updating the asynchronous event handler in network_if.c.
