Sources directory

The sources directory is organized as follow :

There are mainly two sub-directories “Samples” and “WizeCore”. “WizeCore” is the stack implementation, while “Samples” contains some required libraries by the Wize stack. The WizeCore is split in four folders, each one corresponding more or less to an abstraction layer.

CRC_sw

CRC_sw library provides functions to compute and check the CRC16 (Cyclic Redundancy Check) as specified by Wize Lan Protocol Specifications v1.2.

Crypto

Crypto library provides interface functions to cipher, uncipher, compute AES-CMAC and SHA256. This module relies on tinycrypt library located in “third-party/libraries/Tinycrypt” directory (https://github.com/intel/tinycrypt.git).

ReedSolomon

ReedSolomon library implement Reed-Solomon code correction algorithm RS(255,223). This module is a port of the http://www.eccpage.com/rs.c

ImgStorage

ImgStorage library provides an interface for storing downloaded firmware block on physical memory.

Parameters

Parameters library provides interfaces to set and get parameters.

TimeEvt

TimeEvt module provides event to the task at the required time.

Logger

Logger module provides a way to log out messages (info, warning, error, debug).

WizeCore sub directory

proto

proto implement all necessary to treat the link and presentation layer from the Wize protocol, that is :

  • build/extract the Link and Presentation Layers information

  • cipher/un-cipher the application message

  • compute and check the authentication hash

  • compute and check the confidentiality hash

  • compute and check the CRC

  • compute and check the Reed-Solomon code and correct the frame when possible (Download layer only)

proto depends on the “CRC_sw”, “Crypto” and “ReedSolomon” libraries.

net

net implements a kind of low-level driver to :

  • drive the protocol in proto

  • provide an abstract layer to higher level, with function like “send(…)” or “recev(…)”.

  • provide an interface to the phy driver implementation

net depends on proto

mgr

mgr implements four managers :

  • adm_mgr, inst_mgr and dwn_mgr manage respectively the administration, installation and download sessions. Their role is mainly to ensure the session timing correctness.

  • net_mgr is a kind of high level driver for the net module. In particular, it manages the net+phy resources in thread-safe manner and ensure the timing correctness in the “send” and “listen” windows.

mgr depends on net, TimeEvt, Logger and FreeRTOS.

app

app implements application layer of the Wize protocol and provide an API to the rest of application firmware.

  • provide API to send DATA message and execute an installation (PING/PONG) session

  • open/close administration, installation and download sessions.

  • build/extract generic administration layer (aka DATA, COMMAND, RESPONSE)

  • build/extract installation layer (aka PING/PONG)

  • deal with downloaded firmware image (store, validate)

app depends on mgr, TimeEvt, ImgStorage, Parameters, Logger and FreeRTOS.
