elf:
Demonstrates execution of ELF file from a file system using
apps/examples/elf. This is a very simple configuration so there is not
really much that needs to be said.
NOTES:
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.
