[Buildroot] 2011.02, BeagleBoard-xM, linux-2.6.37 does not boot

[Torsten Mohr]

Hi,

i configured and compiled buildroot-2011.02, which comes with 2.6.37 as the 
default kernel setting.  I chose this one and "omap2plus" as the defconfig 
name.

u-boot.bin boots fine, but the kernel does not show any output.  All i see is:

reading uImage

Uncompressing Linux... done, booting the kernel.

There's nothing more after this.  I also tried "omap3" as defconfig (and 
copied that 0map3_defconfig from a previous kernel, same result).

Not sure if i missed something, some questions came up:

- does buildroot use the correct kernel for BeagleBoard-xM?
- do i need to apply patches?
- what configuration file do i need to chose?
- does u-boot need special options to boot that kernel?

It would be great if anybody had some hints for me.


Best regards,
Torsten.

Maybe you need setenv console=/dev/ttyO2

Hello,

thank you for your hints,

When configuring the kernel i found out that this is actually set as the 
internal CMDLINE.

Also (other hint), the kernel debugging options in the kernel are set.

I compiled a kernel today and i can boot it, it does not boot using the 
standard scripts that came with the Angstroem distro.

When interrupting standard boot and giving:

mmc init
mmc rescan 0
loaduimage
bootm 0x82000000

Then the kernel starts to boot.


Thanks for your hints,
Torsten.

[Buildroot] build without linux, busybox, - just buildroot internal toolchain

[Steve Calfee]

Hi

I am trying buildroot partitioned into systems. In my toolchain only 
tree, I disable both kernel, busybox, and all packages. This works, but 
for some reason the entire linux kernel is unpacked in the 
output/toolchain/linux-2.6.37.2. I am not clear on why the toolchain 
needs linux headers, but ok, why does it need the full source?

Here is my buildroot .config

[Buildroot] build without linux, busybox, - just buildroot internal toolchain

Hi Steve,

Any toolchain that generates binaries running under Linux needs header files 
from the Linux kernel. These headers define the kernel ABI (Application Binary 
Interface), such as system call numbers, structs, etc. Userspace programs 
include these headers either directly (from the linux/ directory), or 
indirectly via you libc of choice.

The Linux headers are not supplied in a separate package. You need to generate 
them from the Linux source.

Hope this helps.
