Greetings, I successfully built and booted Linux 3.1 for the beaglebone (TI am335x) using the 4.5.2 toolchain. I rebuild the same kernel using the same config with the 4.6.3 toolchain, but the board hangs at "Uncompressing Linux... done, booting the kernel." I halt the beaglebone at the U-Boot prompt and have it download and run uImage from an NFS mounted RFS. The Linaro 4.5.2 toolchain was installed in my Ubuntu 11.04 distro using aptitude. The Linaro 4.6.3 toolchain binaries, downloaded via Launchpad, were installed into my own tools directory. *4.5.2 INFO:* ./gcc-linaro-arm-linux-gnueabi-2012.01-20120125_linux/bin/arm-linux-gnueabi-gcc --version arm-linux-gnueabi-gcc (crosstool-NG linaro-1.13.1-2012.01-20120125 - Linaro GCC 2012.01) 4.6.3 20120105 (prerelease) Copyright (C) 2011 Free Software Foundation, Inc.
