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 linux-menuconfig

Armadeus specific drivers --->

[...]
[*] virtual components

[*] Board designs
[...]
<M> board driver for sp_vision fpga loader
then
[ ]$ make linux [...] [ ]$ 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:
# load_fpga apf51_spvision_loader.bin
- Once the first FPGA configured, just do :
# modprobe sploader # modprobe sploader_prober # dd if=your_sp_vision_bitstream.bit of=/dev/sp_loader
Communicate with sp_vision
