CFDP Utilities

Overview

This directory contains CFDP utility classes used by the F' Framework.

Contents

  • Checksum/: CCSDS CFDP-compliant 32-bit checksum implementation

Where is CfdpManager?

The main CFDP protocol implementation is located at:

Svc/Ccsds/CfdpManager/

If you're looking for the CFDP file transfer component, you'll find it there.

Why is Checksum here?

The Checksum utility is used by the F' Framework's FilePacket class (Fw/FilePacket/FilePacket.hpp), which predates the CfdpManager component and supports legacy file transfer components (FileUplink, FileDownlink). To maintain framework independence, Checksum cannot be moved into CfdpManager.

Future

A long-term solution would be to relocate Checksum to a framework utilities directory (e.g., Fw/Utils/), further clarifying the architectural separation.
