Zeratul - themactep/thingino-firmware GitHub Wiki

The Ingenic Zeratul, Atlas, and Tassadar platforms are a series of System-on-Chip (SoC) solutions designed primarily for battery-powered IoT cameras and smart home devices. The platforms emphasize low power consumption while maintaining persistent Wi-Fi connectivity.

Zeratul Features

• Persistent Wi-Fi Connectivity: Maintains a stable network connection even in low-power states
• Extended Battery Life: Power management design allows devices to operate for 6+ months on battery power
• Remote Access: Always-available remote viewing capabilities
• Power Management: Uses external micro-controllers for sophisticated power management

Hardware Architecture

The platform typically employs a two-chip design:

1. Main Ingenic Zeratul SoC
2. External micro-controller for power management (sometimes integrated in the Wi-Fi module)

Product Lines

• T31 (Codename: Archon)
• T20 (Codename: Immortal)

Power Management

Power efficiency is achieved through:

• Dynamic frequency scaling
• Multiple power states
• Sophisticated wake-up mechanisms
• External micro-controller management of power states

Third-Party Support

Due to the wide variation in:

• Power management micro-controller choices
• Wi-Fi module integrations
• Custom hardware designs

Third-party firmware like Thingino cannot currently provide universal support for Zeratul-based devices. Each device requires specific power management micro-controller code tailored to its hardware configuration.
