cape-universal is also enabled by default with u-boot overlays.. To switch between the 3 different cape-universal overlays, utilize these 4 variables: To Disable eMMC: disable_uboot_overlay_emmc=1 To Disable HDMI VIDEO & AUDIO: disable_uboot_overlay_video=1 To Disable HDMI AUDIO: disable_uboot_overlay_audio=1 To Disable WL1835: disable_uboot_overlay_wireless=1 ps, if you plug in a usb-serial adapter, you'll see exactly what u-boot is loading. ;) 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.
