Hi,

I discovered that in the log, the HDMI is not disabled:

[ 0.000000] Kernel command line: console=ttyO0,115200n8 capemgr.disable_partno=BB-BONELT-HDMI,BB-BONELT-HDMIN,BB-BONE-EMMC-2G root=/dev/mmcblk0p2 ro rootfstype=ext4 rootwait fixrtc quiet init=/lib/systemd/systemd

I checked it with :

export SLOTS=/sys/devices/bone_capemgr.9/slots

root@beaglebone:/home/debian# cat $SLOTS
0: 54:PF—
1: 55:PF—
2: 56:PF—

5: ff:P-O-- Bone-Black-HDMI,00A0,Texas Instrument,BB-BONELT-HDMI
6: ff:P-O-- Bone-Black-HDMIN,00A0,Texas Instrument,BB-BONELT-HDMIN

Why ?

Thx,

Micka,

You are disabling them correctly. They will still show up in the list of capes since they are specified in the main devicetree file, but the lack of a “L” in the status indication in /sys/devices/bone_capemgr.9/slots means they have not been loaded. If they were loaded, those lines would have “P-O-L” instead of “P-O–”.
