I go through the forum, did not find answer about this.
I am using arm-linux-gnueabi to try to build a kernel for beaglebone. I get the source from git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-oamp.git. The system boot and stopped after loading the kernel.
Can anyone tell me what kernel source I need to use?
I would recommend you try the kernel from the Sitara Linux SDK at http://software-dl.ti.com/dsps/dsps_public_sw/am_bu/sdk/AM335xSDK/latest/index_FDS.html.
There is also a GCC toolchain in that SDK
I did download and install the TI SDK system.
Then I setup the environment and make the kernel with the GCC cross tool come with it. I have a compaining of shared library libz.so.1. How can I build this or get from somewhere?

Never mind, I found it.
It also looks like you sourced the environment-setup script. You do NOT want to do that when building the kernel because it will cause some of the host tools the kernel uses to be cross-compiled for the ARM instead.
I still have the same complain from the compiler.
I tried to guess to set the library path EXTRALDFLAGS := /linux-devkit/arm-arago-linux-gnueabi/usr/lib in file /script/Makefile.build
It still failed to find the libz.so.1 in /linux-devkit/arm-arago-linux-gnueabi/usr/lib . can you tell me what I am missing?
It turns out I have 64bit machine, I am missing 32bit library lib32lz.1
Now it compiles.
Now the system is up with the kernel and u-boot I built based on your source. Thank you!
Do you have a git site I can directly get the kernel and u-boot source without all the install things?
Also can I disable the power management unit. What is the purpose of am335x-pm-firmware.bin?
run into the same problem. Where I cn get this lib32lz.1 library?
Thanks in advance
Sorry for the typo. You should install the lib32z1 library in your machine. For Debian I use apt-get to install it.
