[OpenRISC] GSoC 2018: Create a generic debug interface for soft-CPU core (or1k) and connect it to GDB- Shivam Aggarwal

[SHIVAM AGGARWAL]

Hi everyone,

I am Shivam Aggarwal and have been selected for Google Summer of Code 2018
to work with TimVideos. for the project “Create a generic debug interface
for soft-CPU core (or1k) and connect it to GDB”.

Project Description

The aim of this project is to create a run-control debug system for soft
CPU core (or1k) used in HDMI2USB/LiteX firmware and add GDB to the system
using Open SoC Debug Project.

The Open SoC Debug (OSD) is an extensible, modular specification which
enhances SoCs with debug and tracing functionality. Currently, it supports
trace debugging and provides internal system access. As part of this
project, run-control debugging specific module, i.e. CDM module and
gdb-server bridge will be added to OSD. This will allow us to temporarily
suspend the software execution on the SoC. The control over the execution
flow is then handed over to GDB (GNU Debugger).

The second phase of the project is to integrate the OpenSoCDebug into
HDMI2USB/Litex firmware. It will help in debugging the running code on
Litex firmware, eg. issues encountered while running Linux on the real
hardware.

Hi Shivam,

Good luck with your project. You may find some of the Embecosm
Application Notes on interfacing hardware to GDB useful (in particular
EAN4)

  https://www.embecosm.com/resources/appnotes

You should think in particular about how multicore debug will work,
and the implications for your GDB server implementation. You'll need
to be able to support all-stop and non-stop modes, and hence
asynchronous debugging.

Best wishes,


Jeremy
