Gdb for Embedded Systems: REMOTE DEBUGGING, JTAG, AND KERNEL DEVELOPMENT: Debug ARM, RISC-V, and Microcontrollers with gdbserver, Cross-Compilation, a

Master remote GDB debugging for real embedded failures, not toy examples.

When an ARM or RISC V board hangs, reboots, or deadlocks under load, ad hoc breakpoints and guesswork are not enough. You need a way to prove which core you halted, which image you loaded, why execution stopped, and how to get back to that same state on demand.

GDB for Embedded Systems: Remote Debugging, JTAG, and Kernel Development gives you a complete, evidence driven workflow for controlling real hardware through gdbserver, OpenOCD, and KGDB. You will learn how to move from ＂it kind of works＂ sessions to repeatable transcripts, proof artifacts, and recoverable crash investigations across firmware, embedded Linux, and kernel space.

• Map your debug topology so you know exactly which GDB stub, transport, and target remote endpoint controls each core.
• Stabilize OpenOCD sessions with reproducible .gdbinit entry sequences, reset and halt behavior, and multi TAP target selection.
• Route gdbserver connections reliably across TCP, SSH tunnels, supervisors, and multi process setups without attaching to the wrong image.
• Normalize symbols with sysroot, solib-search-path, and substitute-path so shared libraries, PIE binaries, and container builds resolve to the right source files.
• Bring KGDB and vmlinux into play for kernel panics, deadlocks, and module reloads, including post reboot symbol resync.
• Budget hardware breakpoint and watchpoint resources to catch stack overflows, DMA corruption, and first bad stores without exhausting comparators.
• Control Remote Serial Protocol (RSP) behavior, vCont packets, and interrupt delivery so stepping and break requests remain predictable under stress.
• Capture proof artifacts for every stage, from initial connection transcripts and crash entry triads to recovery logs and replayable session packages.
• Apply the same control and evidence pipeline across board bring up, firmware crash hunts, embedded Linux integration, and kernel deadlock chase scenarios.

The guide is code heavy in a practical way, with working GDB command files, Shell and Systemd snippets, OpenOCD scripts, and RISC V specific setups that you can adapt directly to your own boards and targets.
