Move boards to boards folder
* boards: rename configs folder to boards
This is the proposed layout after the change:
boards: - folder containing board folders
<board>: - name of each board
drivers: - extra drivers specific for platform
include: - header files for the boars
scripts: - extra scripts specific for platform
src: - board specific code
tools: - extra tools specific for platform
<config>: - board specific configuration(s)
Note:
<xxx> names are dependent on platform
This is a logical change to aim to the arch layout but this is a
huge change it should be done in several steps to lower the risk.

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
|
