Hi guys!
I’m building an embedded system based on BBB Android on Beagle Bone Black hardware.
I needed to disable HDMI because i need to set the pins free so i added “capemgr.disable_partno=BB-BONELT-HDMI,BB-BONELT-HDMIN” to mmcargs into uEnv.txt
Now the HDMI firmware is not loaded as the slots file says:
`
root@beagleboneblack:/ # more /sys/devices/bone_capemgr.9/slots
more /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-- Bone-Black-HDMI,00A0,Texas Instrument,BB-BONELT-HDMI
6: ff:P-O-- Bone-Black-HDMIN,00A0,Texas Instrument,BB-BONELT-HDMIN
`
Unfortunally, without the HDMI firmware, the SurfaceFlinger complains about it, and zygote just can’t start.

Any idea about a workaround of this?
Can an Android work without the User Interface?
