Transfer and Run "Hello World!" application to LCDK problem in minicom

Can you please tell me what you are trying to do ?
Want to run helloworld code on OMAPL138 LCDK ?
If yes, how did you compile ?
If you compile it using arago toolchain you should boot Linux and run the code.
If you compile the code using CCS then run the code using emulator.
What is the hello world code and where did you get from ?
Please clarify me what you are trying to do.

i just want to cross compile helloword code in arago tool chain, i got it
but i am stucked in building deconfig and makeconfig that i have posted in last post please help me through it

NOTE: The --enable-* parameters unconditionally force options on, completely
skipping autodetection. This behavior is unlike what you may be used to from
autoconf-based configure scripts that can decide to override you. This greater
level of control comes at a price. You may have to provide the correct compiler
and linker flags yourself.
If you used one of these options (except --enable-gui and similar ones that
turn on internal features) and experience a compilation or linking failure,
make sure you have passed the necessary compiler/linker flags to configure.
If you suspect a bug, please read DOCS/HTML/en/bugreports.html.
