Runtime Trace Mode is a specialized operational state within advanced flash tools (notably SP Flash Tool for MediaTek) that enables real-time logging of execution paths, register values, interrupt requests, and memory access patterns while the target device is running its low-level firmware or bootloader stages. Unlike a simple debug log, which records events after they happen, Trace Mode captures a chronological, instruction-level stream of activity as it occurs. This mode is activated by selecting specific trace options—e.g., “UART Trace,” “USB Trace,” or “Memory Dump”—before initiating a flashing or booting sequence. The output is a continuous data stream saved to a .bin or .log file, which can later be parsed with companion software (like a debugger or trace analyzer).
The Smartphone Flash Tool is a software utility used to flash firmware on smartphones. To enhance its debugging capabilities, we introduce a new feature: . This feature allows developers and advanced users to monitor and analyze the flashing process in real-time, providing valuable insights into the tool's operations. These logs are crucial for troubleshooting complex "BROM"

: It enables automated screenshots to capture the exact UI state when a memory conflict or transfer failure occurs.
For a holistic view, run adb logcat -b all simultaneously while trace is active. Align timestamps (ensure both use CLOCK_MONOTONIC) to correlate userspace logs with kernel traces.
