NuttX-5.7

This is the 54th release of NuttX. This release adds basic support for one new ARM Cortex-M3 architecture:

• Added support for NXP LPC1768 MCU as provided on the Nucleus 2G board from 2G Engineering (http://www.2g-eng.com).

• Some initial files for the LPC17xx family were released in NuttX 5.6, but the first functional release for the NXP LPC1768/Nucleus2G occurred with NuttX 5.7.

• That initial basic release included timer interrupts and a serial console and was verified using the NuttX OS test.

• That release includes a verified NuttShell (NSH) configuration (see the https://nuttx.apache.org/docs/latest/components/nsh/index.html).

• Also included are unverified SPI and USB device drivers.

Further efforts include: (1) development of a DMA support library (2) SPI-based MMC/SD support (3) verification of the USB driver

Watch for announcement of the completed LPC1768 port expected in NuttX-5.8.
