Instructions to build the driver for petalinux /yocto:

Petalinux Flow

These instructions assume you have already built a petalinux project for your system

Navigate to the petalinux project and source the petalinux settings.

Create a template module for your petalinux project.
	$ petalinux-create --type modules --name vsidriver

The name must be lowercase and must not contain special characters, we suggest you call is vsidriver

Within the created module template make a symbolic link to driver files

	$ rm <name>.c
	$ rm Makefile
	$ mkdir xdma
	$ ln -s ~/<<VSI_FPGA_DIR>>/driver/*.c .
	$ ln -s ~/<<VSI_FPGA_DIR>>/driver/*.h .
	$ ln -s ~/<<VSI_FPGA_DIR>>/driver/Makefile .
	$ ln -s ~/<<VSI_FPGA_DIR>>/driver/xdma/*.c xdma/.
	$ ln -s ~/<<VSI_FPGA_DIR>>r/driver/xdma/*.h xdma/.

Modify the recipe_name.bb as shown below (or use vsidriver.bb as and example):

	SRC_URI = "file://Makefile \
			file://*.c \
			file://*.h \
			file://xdma/*.c \
			file://xdma/*.h \
			file://COPYING \
		"

And append the following to the end:

	inherit module
	EXTRA_OEMAKE = 'KERNEL_SRC="${STAGING_KERNEL_DIR}" \
				O=${STAGING_KERNEL_BUILDDIR} \
				'

Clean, build, install the module and build petalinux:

	$ petalinux-build -c vsidriver -x do_clean
	$ petalinux-build -c vsidriver -x do_build
	$ petalinux-build -c vsidriver -x do_install

The driver will now be in the filesystem at:

	/lib/modules/<version>-xilinx/extra/vsi_driver.ko
