Week-1 @RTEMS-GSoC-2025

Overview

This week is the first week working with RTEMS as a GSoC Contributor. this week lies in the Community Bonding Period - a time when we start diving deeper into the codebase of our project and become more familiar with it. This week, I majorly studied existing GRETH Network Driver in RTEMS Legacy Networking Stack

Work completed this week

1. Studied the GRETH Network Driver in RTEMS Legacy Networking Stack in detail :

   • GRETH Hardware initialization
   • Working of some of the registers of PHY and GRETH MAC (Media Access Controller)
   • Autonegotiation process
   • GRETH Interrupt Handler
   • Relationship between memory buffers and ring descriptors as well as their working
   • Packet transmission and reception mechanism in the driver

2. Created Doxygen comments for all the functions of this GRETH Driver at my fork of Legacy Networking Package as well as a Doxyfile, currently only for GRETH driver for simplicity and organizaion for creating GRETH specific documentation.

This week mostly was a study phase for my project.

Plans for next week

1. Study RTEMS lwIP Package in depth
2. Create blogs till Week-1
