SP VISION

Introduction

The SP_Vision board is an extension of APF27Dev and APF51Dev with a Spartan6 and two DDR. It is designed for real-time video processing.

Configure the sp_vision fpga

SP_Vision FPGA configuration is done through APF* FPGA, then to configure the SP_Vision FPGA you will need a configuration virtual component called sp_vision_configure under the APF*'s onboard FPGA. This virtual component is available in POD library, but if you don't want to make special design just for configuration, a standard design is provided in armadeus tree.

On the APF*_Dev

• First select the driver for sp_vision_configuraton under linux-menuconfig :

[ ]$ make linux26-menuconfig

Device Drivers  --->       
    Armadeus specific drivers  --->
        FPGA Drivers   --->
            [...]
            [*]   virtual components
            [...]
            [*]   Board designs
            [...]
            <M>     board driver for sp_vision fpga loader

then

[ ]$ make linux26
[...]
[ ]$ make
[...]

The configuration bitstream can be found under the directory firmware/pod_scripts/ and it's named apf27_spvision_loader.bit for APF27 and apf51_spvision_loader.bin for APF51. To configure the second (sp_vision) FPGA, first FPGA on APF* must be configured with this bitstream.

• Configure the first fpga (if you transfer files by nfs):

 # modprobe fpgaloader

On APF27:

 # load_fpga apf27_spvision_loader.bit

On APF51:

 # dd if=apf51_spvision_loader.bin of=/dev/fpgaloader

• Once the first FPGA configured, just do :

 # modprobe sploader
 # modprobe sploader_prober
 # dd if=your_sp_vision_bitstream.bit of=/dev/sp_loader
