As we have discussed, the environment for embedded development usually involves two systems—a build system and a target system (or emulator). Sometimes, interactive debugging on the target system is impractical because of the high latency of remote communication.
In such situations, developers can use remote debugging support provided by GDB. In this setup, an embedded application is launched on the target system using gdbserver. Developers run GDB on a build system and connect to gdbserver over the network.
In this recipe, we will learn how to start debugging an application using GDB and gdbserver.
