Daniel P. Carvalho 82f78ddaa0 arch/mips/pic32mz: add Ethernet support for PIC32MZ-W1.
- PIC32MZ-W1 only has the RMII interface and no DEVCFG3, so hide the
  PIC32MZ_FMIIEN and PIC32MZ_FETHIO options and define
  CONFIG_PIC32MZ_FMIIEN as 0 (RMII), matching DEVCFG1.FMIIEN.  The
  default of 1 (MII) made the driver skip the RMII reset and speed
  setup, so the MAC ran its RMII logic at 10 Mbps.
- Enable ETH_CLK_OUT (EWPLLCON.ETHCLKOUTEN), the 50 MHz RMII reference
  clock for the MAC and the PHY, only when the Ethernet MAC is enabled.
- Add PIC32MZ_W1_ETH_EXTREFCLK for boards that clock the PHY and the
  MAC from an external 50 MHz oscillator; ETH_CLK_OUT is then left
  disabled.

Apache NuttX is a real-time operating system (RTOS) with an emphasis on standards compliance and small footprint. Scalable from 8-bit to 64-bit microcontroller environments, the primary governing standards in NuttX are POSIX and ANSI standards. Additional standard APIs from Unix and other common RTOSs (such as VxWorks) are adopted for functionality not available under these standards, or for functionality that is not appropriate for deeply-embedded environments (such as fork()).

For brevity, many parts of the documentation will refer to Apache NuttX as simply NuttX.

Getting Started

First time on NuttX? Read the Getting Started guide! If you don't have a board available, NuttX has its own simulator that you can run on terminal.

Documentation

You can find the current NuttX documentation on the Documentation Page.

Alternatively, you can build the documentation yourself by following the Documentation Build Instructions.

The old NuttX documentation is still available in the Apache wiki.

Supported Boards

NuttX supports a wide variety of platforms. See the full list on the Supported Platforms page.

Contributing

If you wish to contribute to the NuttX project, read the Contributing guidelines for information on Git usage, coding standard, workflow and the NuttX principles.
