5.  OTA and Development Guide 

If an application’s ack_user_config.h contains

 #define 

ACK_HOST_FIRMWARE_UPDATE

, ImplCore is configured for OTA, and OTA support 

is enabled. 

To prepare an OTA image, customers use the Python scripts in the ota\utility directory 
(Python3 required). Those scripts prepend the header expected by ImplCore’s state 
machine, to a .hex file created by building an MCU application.
