README:

NVidia's fork of OpenOCD

This repository contains NVidia's forks of various versions of OpenOCD modified to support NVidia's chips and platforms.

Overview

The versions of OpenOCD available on this repository can be used to attach and debug various NVidia chips including:

-Grace (branch openocd-0.12.0)

-Thor (branch openocd-0.12.0)

-Vera (branch releases/strata(stable) and openocd-0.12.0(dev))

OpenOCD is used in this context to act as a gdb server and convert GDB commands into debug requests to the various debug agents built into NVidia's chips then transmit them over JTAG or CSWP to the part.

Origin of this derivative work

The work in this repository is based on the Open Source project OpenOCD.

Getting Started

See each branch README for instructions on how to build and run that specific version of OpenOCD.

Quick

In general the following instructions should work:

./bootstrap
mkdir build
cd build
../configure --prefix=$DEST
make install -j8

With CSWP support

To enable CSWP support you must first clone the CSWP repository, build and install the code into $DEST. Then in your clone of the appropriate branch of this repository run:

./bootstrap
mkdir build
cd build
../configure --prefix=$DEST --enable-cswp --enable-ftdi CFLAGS="-I$DEST/include"
make install -j8
mkdir -p $DEST/share/openocd/contrib/nvidia
cp $DEST/lib/libcdebug_client.so $DEST/lib/libcstrace_client.so $DEST/share/openocd/contrib/nvidia/

Requirements

Building is supported on x86_64 Linux host only (tested on Ubuntu 18.04+, CentOS 7+ and Rocky Linux 8+). Supported OS: Ubuntu 18.04+, CentOS 7+, Rocky Linux 8+ and OpenBMC.
