PPI and I2C on BF548 EZ-KIT

Hello,

We want to enable PPI and I2C (functions like i2c-detect).

 

Initially we downloaded the toolchains:

1) blackfin-toolchain-2012R2-RC2.i386.tar.bz2

2) blackfin-toolchain-elf-gcc-4.3-2012R2-RC2.i386.tar.bz2

3) blackfin-toolchain-uclibc-default-2012R2-RC2.i386.tar.bz2

from http://blackfin.uclinux.org/gf/project/toolchain/frs/?action=FrsReleaseView&release_id=588

 

We followed all the steps specified in http://docs.blackfin.uclinux.org/doku.php?id=buildroot:build-system:build_a_target#build_a_package for building "buildroot source" from GIT.

Then we did "make bf548-ezkit-fdpic_defconfig" without any errors and followed it up with "make menuconfig" . Then we do"make linux-menuconfig" and  "make". It generates uImage, but we are not able to generate the files related to I2C or PPI(bfinppi.c/Generic blackfin ppi driver).

 

I am attaching the config file generated at /home/abc/BF548-2013/BuildRoot/buildroot/output/build/linux-custom for your further reference.

Are there any other options that I need to select in Menuconfig?

 

Thanks,

Nikhil
