Hi, I try to disable HDMI and emmc by editing the file in /boot/uEnv.txt:
optargs=quiet capemgr.disable_partno=BB-BONELT-HDMI,BB-BONE-EMMC-2G Then I reboot , type: cat /sys/devices/bone_capemgr.*/slots See following: Last login: Sat Jan 1 00:00:22 UTC 2000 on ttyGS0 root@beaglebone:~# cat /sys/devices/bone_capemgr.*/slots 0: 54:P---L BeagleBone RS232 CAPE,00A1,Beagleboardtoys,BB-BONE-SERL-03 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 With letter L, it means it is still enable.. It does not work.,, So what is wrong, how could I do? I am using latest Angstrom image (2013-06-20).. Also, according to some post in Forum, no matter what I change the dtbo file in /lib/firmware/ (to disable /enable uart) It has no effect when it reboot.. I just could change in run time, not in boot time....
