checked the linked config from fhunleth, it seems in the used kernel
tree (
), the usb and the ethernet support is broken (or, as it always
possible, i failed something).
 So to get a working kernel, i used the patchset from
https://github.com/RobertCNelson/linux-dev/tree/am33x-v3.8 ,
( which patches are extracted from the Angstrom build tree ), applied
them manually on the mainline tree, created a tarball, and used that to
build with Buildroot.
So far everything works well (UART,USB host/gadget, ethernet, GPIO
tested). I wondering, would it be possible to apply those subdir-style (
https://github.com/RobertCNelson/linux-dev/tree/am33x-v3.8/patches )
patches automatically in Buildroot on an elegant way? Or better to
create a git tree with applied patches somewhere online and use that in

Thanks, best regards,
