Yeah, don't share v4.4.x-ti kernel dtbs with ti-u-boot v2017.01... It took a long time to get the tiodelay driver into upstream kernel. At one point, the plan was to "everything" in u-boot and the kernel would not touch the iodelay/pinmuxing.. btw, once v2017.11-rc1 get's tagged, i'm moving the x15 based targets to mainline u-boot. ;) 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.
