Building kernel for beaglebone black

Hi All,

I have tried using angstrom toolchain from link below,

http://www.angstrom-distribution.org/toolchains/angstrom-2011.03-i686-linux-armv7a-linux-gnueabi-toolchain-qte-4.6.3.tar.bz2

it is giving this error …

Error: unrecognized option -mauto-it

Can you give the build procedure, where I can find the toolchain?

Thanks & Regards,

Anil Kolli.
