This technical User’s Guide describes the hardware architecture of the SK-AM64B. The SK-AM64B (henceforth referred as AM64x SKEVM or simply SKEVM). The AM64x processor comprises of a Dual-Core 64-bit Arm-Cortex A53 microprocessor, 2x Dual core Arm® Cortex®-R5F MCUs and an Arm Cortex-M4F MCU. The AM64x starter kit is a stand-alone test and development platform that is ideal for accelerating the prototype phase of your next design. The kit includes: wired and wireless connectivity, three expansion headers, multiple boot options and flexible debug capabilities.

The starter kit is equipped with AM64x processor from TI and an optimized feature-set to allow the user to create commercial and industrial solutions using Ethernet-based, USB, and serial wired interfaces plus 2.4-GHz and 5-GHz wireless communications. Two 1-Gbps Ethernet Ports for wired connectivity are on-board, in addition to three expansion headers (PRU, MCU, User) headers to expand the board’s functionality. Using standard serial protocols such as UART, I2C, and SPI, the starter kit can interface with a multitude of other devices, acting as a communications gateway. Receiving 5-V power from a standard USB-C port, the starter kit allows the user to access the R5F cores of the AM64x, making it suitable as a programmable logic controller (PLC) or motor controller, processing sensor inputs and managing peripherals in real-time while running Linux on the A53 cores, making it the central engine in a remote industrial communication network. The embedded emulation logic allows for emulation and debugging using standard development tools such as Code Composer Studio™ from TI.
