Find your kernel source tree, and edit src/Makefile. Locate the following line:
KERNEL_PATH = /usr/src/linux-headers-*.*.*-**-generic`
Modify this line so that it points to the correct source tree.
After that, run make to create fl2000.ko and run insmod fl2000.ko to load the driver.
In the sample folder, run make to create fltest. If you you are using a
cross compiler to build the binary for specific platforms, you need to specify that specific
compiler in src/Makefile.
Run ./fltest 0 as superuser to run the test. The driver provides several
user mode buffer access methods (e.g copy to kernel internal buffer, or
directly locking down user buffer). Look at fl2000_ioctl.h for detailed
information.
