I new working Linux on board which isn't supported to that moment in Buildroot, I think - AT91SAM9G45 on Ronetix board. Is it possible to build for it? Moreover I will use external Kernel which support 9g45 - Kernel version 2.6.30. That version isn't supported from the Kernel headers, I think? Can you help me build the Linux again? Thanks, Martin.
