Buildroot

Postby frgodzilla » Thu Jul 19, 2012 5:05 am

I just got Buildroot working on the RPi. If anyone's interested in the .config file, I can post it along with the external CT-NG configuration.

Did you manage to make the target with VFP and hardfloat ?

So, i added --with-float=hard Additional gcc options together with disabling prefer soft float and
marking VFP in toolchain options and that worked 8-)

Here are my configs. GCC+glibc+hard float, but not optimized for VFP. Should be trivially add-able via the ctng config.

I am very new in this Raspberry matter, although have some experience with Buildroot. As much as I can see, you have bult text mode only and kernel altogether. Also, I think kernel compiling results in uImage file. So, where did you put it (instead of kernel.img ?) ? Have you tried (if it is possible) to boot via NFS - I consider it to be good for development. If so, can it be done without u-boot ?
I hope I can add Qt to your config to achieve graphic.
