Use webcam in BF-609 to show images on WVGA\LCD EI3 Extender Board

I want to use webcam (Logitech C170) in ADSP-BF609 (ez-kit) to show images on WVGA/LCD EI3 Extender Board. At first, I thought I can add USB driver and WVGA/LCD Board driver in my kernel.

Thus, I followed this website (http://docs.blackfin.uclinux.org/doku.php?id=developing:blackfin_live_sources) to build the kernel.

I used :

$ mkdir ~/blackfin-sources

$ cd ~/blackfin-sources

$ git clone git://git.code.sf.net/p/adi-toolchain/blackfin toolchain

$ git clone git://git.code.sf.net/p/adi-u-boot/code u-boot

* the uclinux sources are no longer available

$ svn checkout svn://blackfin.uclinux.org/uclinux-dist/trunk uclinux-dist

( ** I didn't use this command with strikethrough. **)

$ git clone git://git.code.sf.net/p/adi-linux/code uclinux-dist/linux-2.6.x

$ git clone git://git.code.sf.net/p/adi-buildroot/code buildroot

$ git clone git://git.code.sf.net/p/adi-linux/code buildroot/linux/linux-kernel

Build the toolchain:

$ ~/blackfin-sources/toolchain/buildscript/BuildToolChain -p

$ mkdir ~/blackfin-sources/build

$ ~/blackfin-sources/toolchain/buildscript/BuildToolChain \

  -b ~/blackfin-sources/build \

  -k ~/blackfin-sources/buildroot/linux/linux-kernel \

  -s ~/blackfin-sources/toolchain \

  -u ~/blackfin-sources/u-boot

Setting my path:

$ export PATH=~/blackfin-sources/build/bfin-elf/bin:~/blackfin-sources/build/bfin-uclinux/bin:~/blackfin-sources/build/bfin-linux-uclibc/bin:${PATH}

and build the kernel (website: http://docs.blackfin.uclinux.org/doku.php?id=basic_compilation)

bash$ make menuconfig

I edited these sections as follows:

Then, i got a error are

perl: warning: Falling back to the standard locale ("C").

I’ve not yet added webcam or usb driver and WVGA/LCD EI3 driver to my kernel coz I had two errors when I tried to add WVGA/LCD driver in my kernel.

The following are the errors:

arch/blackfin/mach-bf609/boards/ezkit.c:1123: error: 'bfin_capture_data' undeclared here (not in a function)

arch/blackfin/mach-bf609/boards/ezkit.c:1263: error: 'bfin_display_data' undeclared here (not in a function)

make[1]: *** [arch/blackfin/mach-bf609/boards/ezkit.o] Error 1

make: *** [arch/blackfin/mach-bf609/boards] Error 2

Can anyone nicely help me to solve these errors? After solving the first problem when I built the kernel, I will provide the drive error information. Thank you for your kind assistance.
