==========
This is the README file for the port of NuttX to the Freescale Kinetis
KwiStick K40. Refer to the Freescale web site for further information
about this part:
http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=KWIKSTIK-K40
The Kwikstik is used with the FreeScale Tower System (mostly just to
provide a simple UART connection)

TWR-SER Serial Board Connection
===============================
The serial board connects into the tower and then maps to the tower pins to
yet other functions (see TWR-SER.pdf).
For the serial port, the following jumpers are required:
J15: 1-2 (default)
J17: 1-2 (default)
J18: 1-2 (default)
J19: 1-2 (default)
The two connections map as follows:
A41 RXD0 - Not connected
A42 TXD0 - Not connected
A43 RXD1 - ELE_RXD (connects indirectory to DB-9 connector J8)
A44 TXD1 - ELE_TXD (connects indirectory to DB-9 connector J8)
Finally, we can conclude that
UART5 (PTE8/9) is associated with the DB9 connector

by CONFIG_LCD_MAXPOWER. Requires CONFIG_KINETIS_TIM1.
Configurations
==============
Each KwikStik-K40 configuration is maintained in a sub-directory and

tools/configure.sh kwikstik-k40:<subdir>
Where <subdir> is one of the following:
ostest:
------
This configuration directory, performs a simple OS test using
examples/ostest.
NOTES:
1. This configuration uses the mconf-based configuration tool. To
change this configuration using that tool, you should:
a. Build and install the kconfig-mconf tool. See nuttx/README.txt
see additional README.txt files in the NuttX tools repository.
b. Execute 'make menuconfig' in nuttx/ in order to start the
reconfiguration process.
2. Default platform/toolchain:
CONFIG_HOST_LINUX=y : Linux (Cygwin under Windows okay too).
CONFIG_ARM_TOOLCHAIN_BUILDROOT=y : Buildroot (arm-nuttx-elf-gcc)
CONFIG_ARM_TOOLCHAIN_BUILDROOT_OABI=y : The older OABI version
CONFIG_RAW_BINARY=y : Output formats: ELF and raw binary
