Yes, indeed. Selecting the right kernel to start from is already a non-trivial task, given the plethora of options (we have at least: official Freescale/NXP kernels, community kernels, vendor kernels from board/SOM manufacturers, and the upstream kernel). > >> Re. toolchain: Any recommended version of OSELAS.Toolchain?

Some things that draw my attention, though: - VFPv3-D16 selected whereas iMX6 can do VFPv3-D32 (or just "VFPv3") - NEON not enabled (supported by iMX6) - Thumb mode used by default (not sure why -- wouldn't it be more appropriate to use arm mode by default unless there is an explicit intent to optimize size over speed ?)
