Zxdb is a console debugger for native code compiled with DWARF symbols (C, C++
and Rust). The frontend runs on the host computer and connects to the on-device
debug_agent. This document describes how to set up these processes.
Connecting the client
The zxdb client program is run on the host computer. It can be connected to
the debug_agent via the interactive connect debugger command or it can
automatically connect based on a command-line flag. Both IPv4 and IPv6
addresses are supported (see ffx to find
the address).
zxdb -c "[f370::5051:ff:1e53:589a%qemu]"
Connecting via a script
Scripts may want to automatically launch the agent and client automatically. The script should wait for the port to be open on the target system before launching the client. Automatic retry is not yet implemented in the client.
To clean up the debug agent gracefully when the client exits, pass the
--quit-agent-on-exit command-line flag to the client.
Specifying symbol paths
The debugger expects unstripped ELF files to be available on the local host
system. Symbols on the target are not used. The location where the local build
stores symbols must be passed to the zxdb client.
