ETA, hopefully next week. > Dovetail and EVL ports to v6.8 are now available from the usual repos for all the supported architectures. Only lightly tested so far, but things look good (arm64/fpsimd is back on track). If CONFIG_NET_OOB is set, there are some warnings about missing function declarations in the net/ core which are now turned on for ARM. We may have to live with them until the generic changes required for enabling the UDP support in the xenomai4 netstack are merged. Significant changes are pending in this area. -- Philippe.
