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

Configurations
==============

Each KwikStik-K40 configuration is maintained in a sub-directory and
can be selected as follow:

    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_ARMV7M_TOOLCHAIN_BUILDROOT=y : Buildroot (arm-nuttx-elf-gcc)
       CONFIG_ARMV7M_OABI_TOOLCHAIN=y      : The older OABI version
       CONFIG_RAW_BINARY=y                 : Output formats: ELF and raw binary
