Hi friends;
I am trying to cross compile (on ubuntu vbox) a wifi device driver for raspberry pi platform.
I plan to copy rasbian OS files from raspberry pi to Ubunutu PC (since module building process needs rasbian OS related files).
- But i amnot sure which folder should i copy (/lib and /usr/src ?).
- Is this convenient way? Some forums, it is said it is needed to rebuild rasbian kernel from source on Ubuntu PC via cross compiler tool chain.
After that i need to edit below scrip piece to set env.
- How should i point for KERNELDIR, LINUXDIR and ROOTDIR.
Thanks
