1.2 TI NDK

The Network Development Kit (NDK) https://software-dl.ti.com/processor-sdk-rtos/esd/docs/latest/rtos/index_Foundational_Components.html#ndk is a platform for development and demonstration of network enabled RTOS applications on TI processors and includes demonstration software showcasing capabilities across a range of network enabled applications.

The NDK provides an IPv6 and IPv4 compliant TCP/IP stack working with the TI-RTOS Kernel. It primarily focuses on providing the core Layer 3 and Layer 4 stack services along with additional higher-level network applications. The NDK itself does not include any platform or device specific software. The NDK interfaces through well-defined transport interface, Network Interface Management Unit (NIMU), to the PDK and platform software elements needed for operation.
