* NuttX cmake * px4_macros:Pass the stringified predicate as second arg to static assert CC_ASSERT mapes to the c++ static_assert or provides the same funtionality for c via the other macros. The c++ static assert takes 2 argumants the prdicate and a message. This fixes the lacking second argument. * Updated nuttx and apps submodule to upstream nuttx 7.21+==master This is the latest uptake of upstream nuttx and apps. * ROMFS generate with xxd instead of objcopy * delete nuttx-patches * NuttX update submodules to latest px4_nuttx-master * fix nuttx apps and board dependency * docker_run update to latest container 2017-08-29 * cmake ROMFS portable sed usage * NuttX update submodules to latest px4_nuttx-master
