[Buildroot] Beaglebone build broken ?

[Buildroot] Beaglebone build broken ?

[Vineet Gupta]

Hi,

I'm using the tip of buildroot, to build for beaglebone (using
beaglebone_defconfig) and running into a couple of issues:

1. The hard FPU settings cause uClibc build to break (intermixing of
soft and hard) and an equivalent of below needs to be made to top level
config file.

-BR2_EXTRA_GCC_CONFIG_OPTIONS="--with-fpu=vfpv3 --with-float=hard"
+BR2_EXTRA_GCC_CONFIG_OPTIONS="--with-float=soft"
-# BR2_SOFT_FLOAT is not set
+BR2_SOFT_FLOAT=y

If this is a must, can this be committed to buildroot itself. I can't
propose a patch myself because I'm not sure why it must or must-not be
built with software float.

2. Next, it's failing when trying to get the custom kernel.

A few months back I could successfully build bone image so obviously
this kernel issue was not present then.

Hi Vineet,

Since I originally submitted the patches for the Beaglebone, the
project that I was using this for decided to go with a different
processor. I'll try to post with what I know, but it may be dated.

I don't know enough to comment on this one, but it really doesn't seem
like this should have happened. It seems like if you specify hard
float that you should be able to get it. I haven't been following the
list closely enough to know whether the beaglebone_defconfig needed to
be updated to still use hard float.

I remember having an intermittent issue with getting this kernel a
couple months back and then it went away. This might be transient.

Having said this, the Beaglebone guys changed how they manage their
kernel code. Instead of having the whole kernel on GitHub, they now
just store patches. See
https://github.com/beagleboard/kernel/tree/beaglebone-3.2. I haven't
looked into how this would fit into Buildroot, though. Unfortunately,
once we switched processors, I haven't had time to keep this up to
date.

We are using the git repo of koen kooi here:

https://github.com/koenkooi/linux.git

If you desire, I can share my buildroot configuration.

That would be handy ! I presume that only top level config file has changed.

BTW not sure if I can/should be suggesting, but is there any reason for
not posting that patch to upstream buildroot itself. As it stands the
current bone support in there is broken !

TIA,

It is not done yet by lack of time. I'll try to do it ASAP but don't
expect anything before this week end.
