Coding & Compiling C++ source is very easy.
You must get the file "dev-img" means develop image file.
That image is mounted with squashfs file system.
first,
you must install squashfs kernel support module
and next you get dev_img and decompress the file in your cf/sd card.
in decompressed directory, run script install_image.sh
that's all
but, install_image.sh script's contents must be modified for your environment...
