The platform is composed of two main hardware components: the talos-evk-som and the talos-evk carrier board. The talos-evk-som is a compact System on Module that integrates the QCS615 SoC, PMIC, and essential GPIO connectivity. It follows the SMARC standard, which defines a modular form factor allowing the SoM to be paired with different carrier boards for varied applications. The talos-evk is one such carrier board, designed for evaluation and development purposes. It provides additional peripherals such as UART, USB, and other interfaces to enable rapid prototyping and hardware bring-up. This initial device tree provides the basic configuration needed to boot the platform to a UART shell. Further patches will extend support for additional peripherals and subsystems. The initial device tree includes basic support for: - CPU and memory - UART - GPIOs - Regulators - PMIC - Early console - AT24MAC602 EEPROM - MCP2515 SPI to CAN QCS615 talos-evk uses a Quectel AF68E WiFi/BT module (PCIe for WiFi and UART for Bluetooth), which is different from the RIDE platform. Plan to enable these in a follow-up patch series.
