Thank you for the reply. I tried on a first BeagleBone and it did not work.
I tried on a second BeagleBone Green (transferring the SD Card) and last night it worked all the times I tried. This morning, however, it does not work anymore Da: Robert Nelson Inviato: venerdì 3 novembre 2017 19:50 A: Beagle Board; Claudio La Rosa Oggetto: Re: [beagleboard] Trouble disabling HDMI + EMMC overlays?

Remove both of those changes, if you want to disable hdmi/hdmi-audio/emmc with newer images you have to follow these directions: https://elinux.org/Beagleboard:BeagleBoneBlack_Debian#U-Boot_Overlays enable_uboot_overlays=1 disable_uboot_overlay_emmc=1 disable_uboot_overlay_video=1 enable_uboot_cape_universal=1 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.
