Thanks for your quick responses always. I've tried the Instructions to build the Kernel git clone https://github.com/RobertCNelson/bb-kernel.git cd bb-kernel/
git checkout origin/am33x-v3.8 -b tmp but if use the command ./build_kernel.sh . i get this message after the "resolving deltas process". I've tried several times but it always freezes at 96%. Do you have any Idea what went wrong? this is what i get in the commandshell: root@beaglebone:/bb-kernel# ./build_kernel.sh + Detected build host [Debian GNU/Linux 7.5 (wheezy)] + host: [armv7l] + git HEAD commit: [e496a19d1fed586a7e82c3cd74f0571491a526ca] ----------------------------- scripts/gcc: Using: gcc (Debian 4.6.3-14) 4.6.3 Copyright (C) 2011 Free Software Foundation, Inc.
