GSoC 2026/Cibi P: Hello World Completion on RTEMS (SPARC erc32 BSP) – Introduction

Programs Google Summer of Code
1

Hello everyone,

My name is Cibi P, and I am an Embedded Software Engineer with 2.4 years of experience. I am interested in participating in Google Summer of Code 2026 with RTEMS to improve my knowledge of RTEMS, contribute to open-source development, and collaborate with the RTEMS community.

As part of the GSoC preparation tasks, I have successfully completed the RTEMS Quick Start using RTEMS 7 and built the SPARC erc32 BSP on a GNU/Linux system.

I modified the Hello World example located at:

rtems/testsuites/samples/hello/init.c

by adding an additional print statement (e.g., “Hello from the Dark Side!”). After rebuilding the BSP using waf, I verified the output using the erc32 simulator.

I have attached:

I really enjoyed working with RTEMS and look forward to contributing more and learning from the community as I prepare for GSoC 2026.

It looks like your git config user.name may not be correct, please ensure you are using the correct name.

Add yourself to tracking/2026 · main · RTEMS / Programs / Google Summer of Code · GitLab

Have a look at last year’s directory for some idea how to structure your personal page if you’d like some inspiration.
