Compiling drivers

Users may need to compile the driver for the peripherals. There are
usually two ways: 1) Put the driver source code into the kernel source
code to compile. 2) For the convenience of users, we also provide the
DEB package of"Linux header"and"Linux image"to facilitate users to
compile the"ko"file of the driver directly on the device.

Install

Go to the resource

download page

 and download the DEB packages of "Linux header" and "Linux image":

   linux-4.4.185_4.4.185-8_arm64.changes
   linux-headers-4.4.185_4.4.185-8_arm64.deb
   linux-image-4.4.185_4.4.185-8_arm64.deb
   linux-image-4.4.185-dbg_4.4.185-8_arm64.deb
   linux-libc-dev_4.4.185-8_arm64.deb

Copy all the files to the device and install them through "dpkg"：

   dpkg -i ./*.deb

Compile

Because 'DEB' is compiled on the "x86" host, so some tools need to be
compiled on the device

   cd /usr/src/linux-headers-x.x.xxx/
   make headers_check
   make headers_install
   make scripts
   # It may go wrong, but it doesn't matter

In addition, "module" also needs to be executed：

   depmod -a

If the driver is compiled on the board, after "make install", you also
need "depmod - a"
