Sunplus Loader Tool Exclusive [ Simple × FULL REVIEW ]

The Sunplus Loader Tool is an essential utility for technicians and satellite enthusiasts who work with set-top boxes (STB) powered by Sunplus chipsets. Whether you are dealing with a "boot loop," a "stuck on Logo" error, or simply want to upgrade your receiver’s firmware via a serial connection, having the right loader is critical.

Feature Proposal: "SunPlus Loader Tool — Exclusive Mode"

Goal

Add an "Exclusive Mode" feature to the SunPlus Loader Tool that ensures a single host process has sole access to target devices during critical operations (flashing, partitioning, secure erase) to prevent conflicts, data corruption, and device bricking in multi-client or automated environments. sunplus loader tool exclusive

Key Behaviors

• Single-client lock: When Exclusive Mode is enabled for a session, the tool acquires an OS-level and tool-level lock preventing other instances or clients from accessing attached devices until the session ends.
• Device reservation: Locks are per-device (by serial/UID) and support reserving multiple devices in one session.
• Timeout & heartbeat: Optional lease timeout with heartbeat from the client. If heartbeat missing beyond threshold, lock auto-releases and optionally performs safe rollback.
• Administrative override: Admins can forcibly release stale locks with a justification log entry (requires elevated credentials).
• Safety checks before lock: Tool runs pre-lock checks (device health, battery level, in-use flags from device) and refuses exclusive lock if unsafe.
• Graceful teardown: On normal or interrupted exit, the tool performs cleanup (stop flashing, restore device state, unlock) and emits machine-readable status.
• Audit logging: All lock/unlock events (user, host, PID, timestamps, device IDs, operation types, reason) stored locally and optionally synced to a secure server.
• User notifications: Real-time CLI/GUI notifications when lock acquired, renewed, about to expire, or forcibly released.
• API and CLI support: Programmatic endpoints and CLI flags:
