PI 5 bsp implementation

[Erick_Karanja]

Hello, I am sharing my current progress in the development of the raspberry pi5 BSP.My current work is based on @lostux current mvp implementation and his guidance has been of great help.
’m currently focusing on validating the early boot sequence. At this stage, I am testing and debugging the platform to ensure the system successfully initializes and transfers control to the Init function, confirming that basic bring-up is functioning correctly.
Tools used: Raspberrypi5 development board, OpenOCD, GDB and a raspberrypi debugger

OUTCOME:

The BSP bring-up was successful, with the system reliably booting to and executing the Init function, confirming correct early-stage initialization and control flow

WHAT NEXT?
Run tm27 test and clock based tests on the current implementation
Start up on the SMP implementation for raspberry pi5

Hi @Erick_Karanja, glad to know the notes helped and your system boots.

I might be wrong, but since there’s already a running thread on this project, maybe it would be better to keep the discussions there? It will make things easier to follow and would avoid confusions about the current state of the work for anyone wanting to work on this.

Hello @lostux , for sure. Thank you

BSP for the Raspberry Pi 5 [GSOC'26]

This post should serve as a thread for the work I am doing to add a bsp for the raspberry pi 5. My introduction for GSOC’26: GSOC'26 Introduction & Proof - Preetam. Data and findings: pi5 rtems bsp - Google Docs I am testing this on a physical Raspberry Pi 5 4GB using OpenOCD & GDB. Here’s the update so far: Started with understanding the difference/similarities between the memory & peripheral map of Pi4 and Pi5. I used the following references: bsps/aarch64/raspberrypi/include/bsp/rasp…
