Teensy LC README
================
This is the README file for NuttX on the PJRC Teensy LC. The Teensy LC
is a DIP style breakout board for the MKL25Z64 and comes with a USB
based bootloader. Contributed by Michael Hope.
Development Environment
=======================
All testing was done with the GNU ARM Embedded 4.9 toolchain on
Linux. See https://developer.arm.com/open-source/gnu-toolchain/gnu-rm to download.
Once you've configured and built NuttX, flash the resulting
nuttx.hex file to the board using the Teensy Loader Application.
LEDs
====
The Teensy LC has a single LED. If CONFIG_ARCH_LEDS is defined, then
NuttX will update the LED as the board boots. The summary is:
* LED off: board booting
* LED on: initial stack created
* LED flashing: panic.
See `include/board.h` for details.
Serial Console
==============
The serial console is mapped to UART0 and appears on pins 0 (RX) and
1 (TX). Consider using a 3.3 V USB to serial adapter such as the
Sparkfun #9717 FTDI cable.

This is the NuttX port for the PJRC Teensy LC board. The Teensy LC is a
DIP-style breakout board for the MKL25Z64 and includes a USB-based
bootloader.
Development Environment
=======================
Testing was done with the GNU ARM Embedded 4.9 toolchain on Linux. See
https://developer.arm.com/open-source/gnu-toolchain/gnu-rm for toolchain
downloads.
Once you have configured and built NuttX, flash the resulting ``nuttx.hex``
image to the board with the Teensy Loader application.
LEDs
====
The Teensy LC provides a single LED. If ``CONFIG_ARCH_LEDS`` is enabled, NuttX
updates that LED during boot:
* LED off: board booting
* LED on: initial stack created
* LED flashing: panic
See ``include/board.h`` for the board-specific definitions.
Serial Console
==============
The serial console is mapped to UART0 and appears on pins 0 (RX) and 1 (TX).
Use a 3.3 V USB-to-serial adapter, such as the Sparkfun ``#9717`` FTDI cable.
