Contributions are not currently accepted. If the intended contribution is not related to NXP specific code, consider contributing directly to the upstream lwIP project. Once this lwIP fork is synchronized with the upstream project, such contributions will end up here as well. If the intended contribution is a bugfix or improvement for NXP porting layer or for code added or modified by NXP, please open an issue or contact NXP support.

This fork of lwIP contains specific modifications and enhancements for NXP MCUXpresso SDK integration, including:

• Adaptation layers for some of the network interfaces found on NXP MCU platforms.
• Adaptation layer supporting compilers used with MCUXpresso SDK.
• Operating system abstraction layers for FreeRTOS and bare-metal.
• NXP implementation of HTTP server.
• Bugfixes and modifications of upstream code, which could not be upstreamed directly.
• CMake and Kconfig files for integration with MCUXpresso SDK build system.

See changelog for details.
