The LPC40xx family is very similar to the LPC17xx family except that it features a Cortex-M4F versus the LPC17xx’s Cortex-M3. Architectural support for the LPC40xx family was built on top of the existing LPC17xx by jjlange in NuttX-7.31. With that architectural support came support for two boards also contributed by jjlange:

LX CPU. Pavel Pisa add support for the PiKRON LX CPU board. This board may be configured to use either the LPC4088 or the LPC1788.
