armv7-lpae-x: lpae = https://en.wikipedia.org/wiki/ARM_architecture#Large_Physical_Address_Extension It was added with the Cortex-A15, The Cortex-A7,A12,A15,A17 all have it.. Devices which don't have it, Cortex-A5,A8,A9 will NOT boot with it enabled.. Right now, this only supports the omap5_uevm, BeagleBoard-X15... armv7-x: general image that'll work with most boards... bone: tweaked config for the BeagleBone family (am335x), which enable a few things we can't enable on the general image due to errata on the older Cortex-A8 used on the BeagleBoard/Beagleboard-xM.. (Which allow us to get a little more performance out of the am335x) Regards, -- Robert Nelson http://www.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.
