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.

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* fpga. This virtual component is available in POD library, but if you don't want to make special design for configuration a standard configuration design is provided in armadeus tree.

Configure the sp_vision Spartan6 with apf27-Dev

First select the driver for sp_vision_configuraton under linux-menuconfig :

[ ]$ make linux26-menuconfig

            <M>     board driver for sp_vision fpga loader

then

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

For apf27 the configuration bitstream can be found under the directory firmware/pod_scripts/ and it's named apf27_spvision_loader.bit. To configure the second (sp_vision) FPGA, first (apf27) FPGA must be configured with this bitstream.

Once the first fpga configured, just do :

Configure the sp_vision Spartan6 with apf51-Dev
