JTAG/SWD Debug Skill
Overview
This skill provides deep integration with JTAG/SWD debug probes for hardware-level debugging, flash programming, and real-time firmware analysis. It enables direct hardware interaction through industry-standard debug interfaces.
Capabilities
Debug Probe Operations
- Execute OpenOCD, J-Link, and ST-LINK commands
- Configure debug probe connections and interfaces
- Manage multiple debug probe types and adapters
- Handle transport protocols (JTAG, SWD, cJTAG)
Memory Operations
- Read/write memory-mapped registers
- Direct memory inspection and modification
- Real-time memory watch and modification
- Flash programming and verification
- Memory dump and analysis
Debugging Features
- Set hardware breakpoints and watchpoints
- Core state inspection (registers, stack, PC)
- Single-step execution control
- Fault handler analysis and debugging
- Call stack unwinding
Trace and Output
- Semihosting input/output support
- SWO trace output configuration
- ITM stimulus port configuration
- Real-time trace buffer analysis
Target Processes
hardware-bring-up.js- Initial board validation and debug setupbootloader-implementation.js- Bootloader debugging and flash operationsdevice-driver-development.js- Driver debugging with hardware accessfield-diagnostics.js- Field debugging and analysis
Dependencies
- OpenOCD (Open On-Chip Debugger)
- J-Link software (Segger)
- ST-LINK utilities (STMicroelectronics)
- Debug probe hardware (J-Link, ST-LINK, CMSIS-DAP)
Usage Context
This skill is invoked when tasks require:
- Direct hardware debugging through JTAG/SWD
- Flash memory programming operations
- Low-level register and memory inspection
- Fault analysis and crash debugging
- Hardware breakpoint management
Configuration
debug_probe:
type: jlink | stlink | openocd | cmsis-dap
interface: swd | jtag
speed: 4000 # kHz
target: cortex-m4 | cortex-m7 | etc.
Example Operations
Flash Programming
openocd -f interface/stlink.cfg -f target/stm32f4x.cfg \
-c "program firmware.elf verify reset exit"
Memory Read
JLinkExe -device STM32F407VG -if SWD -speed 4000 \
-CommanderScript read_memory.jlink
Register Inspection
openocd -f board/stm32f4discovery.cfg \
-c "init; halt; reg; resume; exit"
