Robert, thank you - yes I should be able to use them directly, of course. Except I have __NOT__ been able to!
My ubuntu distro has no /boot/uEnt.txt in the FAT partition. Instead the /boot/uEnv.txt appears in the linux filesystem partition and does not do anything at boot time, obviously. I have manually created a /boot/uEvnt.txt on the FAT partition after booting from eMMC, using cat /proc/cmdline > /boot/uEnv.txt and then then added the capemgr enable/disable lines: console=ttyO0,115200n8 quiet drm.debug=7 root=UUID=4c074e4e-40e6-43ad-a0a1-52113ea40176 ro rootfstype=ext4 rootwait fixrtc quiet capemgr.disable_partno=BB-BONELT-HDMI,BB-BONELT-HDMIN capemgr.enable_partno=BB-UART2,BB-UART5 After rebooting a "ls /dev/ttyO*" (that's tty-"capital-oh" not zero) returns only: /dev/ttyO0 and root@arm:/home/ubuntu# cat /sys/devices/bone_capemgr.9/slots 0: 54:PF--- 1: 55:PF--- 2: 56:PF--- 3: 57:PF--- 4: ff:P-O-L Bone-LT-eMMC-2G,00A0,Texas Instrument,BB-BONE-EMMC-2G 5: ff:P-O-L Bone-Black-HDMI,00A0,Texas Instrument,BB-BONELT-HDMI dmesg dumps is here: http://pastebin.com/iT4RWFnq Thanks again, Dejan Nenov On Saturday, August 23, 2014 5:51:41 AM UTC-7, RobertCNelson wrote: > > On Fri, Aug 22, 2014 at 11:41 PM, Dejan Nenov <[email protected] > <javascript:>> wrote: > > Robert, thank you very much, however the overlays are not compiling - I > am > > pretty sure I have the latest dtc: > > Why are you trying to compile them?
