The binaries consumed in the Particle ecosystem should include "module info" descriptors that appear at fixed locations in the binary. There are 2 module info structures:

• start info: appears at the start of the binary, this defines the platform, version, module type, module dependencies
• end info: appears at the end of the binary. Defines product ID and version, as set in user code and provides storage for the SHA256 and CRC32 hashes that are added after the binary is built.

Compiling Module Info

The module info structures are defined in dynalib/inc/module_info.h. The structures are instantiated in dynalib/inc/module_info.inc which defines the default values for all platforms.

The main project compiles the module info structure instances into a module_info.o object file - main/src/module_info.c simply includes module_info.inc from dynalib so the instance declarations become static data.
