How do I cross compile a single module?

问题

What I need to cross compile is the USB gadget serial driver (g_serial.ko). I have my toolchain installed and checked out the sources from kernel.org. Now what to do to just compile that single module? Thanks in advance!!

回答1:

From the kernel source directory

make ARCH=arm CROSS_COMPILE=/your/cross/compile/prefix M=path/to/module/directory

or

make ARCH=arm CROSS_COMPILE=/your/cross/compile/prefix path/to/module/directory
