NOTES:
Since this configuration is based on the ELF configuration, all of
the notes for that configuration also apply.
NOTES:
1. This configuration is based on the elf configuration. Primary
differences between the two configurations are noted below:
1. This configuration uses the the USART3 for the serial console
which is available at the "DBGU" RS-232 connector (J24). That
is easily changed by reconfiguring to (1) enable a different
serial peripheral, and (2) selecting that serial peripheral as
the console device.
2. By default, this configuration is set up to build on Windows
under either a Cygwin or MSYS environment using a recent, Windows-
native, generic ARM EABI GCC toolchain (such as the CodeSourcery
toolchain). Both the build environment and the toolchain
selection can easily be changed by reconfiguring:
CONFIG_HOST_WINDOWS=y : Windows operating system
CONFIG_WINDOWS_CYGWIN=y : POSIX environment under windows
CONFIG_ARMV7A_TOOLCHAIN_CODESOURCERYW=y : CodeSourcery for Windows
If you are running on Linux, make *certain* that you have
CONFIG_HOST_LINUX=y *before* the first make or you will create a
corrupt configuration that may not be easy to recover from. See
the warning in the section "Information Common to All Configurations"
for further information.

5. General build directions:
$ cd nuttx/tools : Go to the tools sub-directory
$ ./configure.sh sama5d4-ek/kernel : Establish this configuration
$ cd .. : Back to the NuttX build directory
: Edit setenv.sh to use the correct path
$ . ./setenv.sh : Set up the PATH variable
$ make : Build the kernel
: This should create the nuttx ELF
$ make export : Create the kernel export package
: You should have a file like nuttx-export-*.zip
$ cd apps/ : Go to the apps/ directory
$ tools/mkimport.sh -x <zip-file> : Use the full path to nuttx-export-*.zip
$ make import : This will build the file system
STATUS:
2014-9-4: The kernel works up to the point where the nsh 'init'
is started from the file system then fails. This is good,
however, because I do not yet have the file system in place yet.
