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).
