Tools and Software

Tools

    LM5157EVM-BSTThe LM5157EVM-BST evaluation module showcases the features and performance of the LM5157 device as a wide input voltage boost converter with dual random spread spectrum. The standard configuration is designed to provide a regulated output of 12V at 1.6A from an input of 3V to 9V (load derated by half from < 6V input), switching at 2.1MHz.
    AWR2544LOPEVMThe AWR2544LOPEVM is an easy-to-use evaluation board for the AWR254x mmWave sensing device, with direct connectivity to the DCA1000EVM. This EVM can be powered via PoDL. Refer to the AWR2544LOP User's Guide for the instructions how to use PoDL on this board.

Software

    ETHERNET-SWThe Linux™ drivers for Texas Instruments' Ethernet physical layer (PHY) transceivers support communication through the serial management interface (MDC/MDIO) to configure and read PHY registers.
    The USB-2-MDIO software lets you directly access the registers during debug and prototyping. This tool supports all TI Ethernet PHYs releases of the DIEP GUI installer, packaged with device description files for automatic connection and detection of Ethernet EVMs.
    PROCESSOR-SDK-LINUX-J721EProcessor SDK RTOS (PSDK RTOS) can be used together with either Processor SDK Linux (PSDK Linux) or Processor SDK QNX (PSDK QNX) to form a multiprocessor software development platform for TDA4VM and DRA829 SoCs within TI’s Jacinto™ platform. The SDK provides a comprehensive set of software tools and components to help users develop and deploy applications on supported J7 SoCs. PSDK RTOS and either PSDK Linux or PSDK QNX can be used together to implement various use cases in robotics, vision, factory and building automation, and automotive ADAS and gateway systems.
