embedded-debug-skill

Systematic debugging skills for real embedded devices. Focus on STM32/ARM Cortex-M + FreeRTOS scenarios, and use Serial Agent/MCP capabilities to complete the closed loop of "obtain现场→analysis→modification→compilation→burning→running→verification". Used when users mention STM32, FreeRTOS, HardFault, I2C/SPI/UART/CAN, DMA, RTOS task exceptions, crashes, intermittent faults, serial port logs, SWD/JTAG, GDB, logic analyzers, oscilloscopes, firmware burning, or need to connect a real development board for debugging.
