A Couple Reasons: TI actually dropped "official" support for OMAP3/DM37xx devices after v3.14.x, so we just use a mainline generic kernel (4.4.1 in that image's case for the xM).. Whereas the 4.1.x-ti based kernel has official support from TI for am335x/am4x/am5x devices.. THUMB2: The omap3/dm37xx, have an early r1pX Cortex-A8 core, this has lots of fun thumb2 errata. So the 4.4.1 based kernel was built in non-thumb2 mode.. Whereas the v4.1.x-ti based kernel has THUMB2 enabled by default.. http://cateee.net/lkddb/web-lkddb/THUMB2_KERNEL.html Regards, -- Robert Nelson https://rcn-ee.com/ -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
