When installing latest archlinuxarm on beaglebone black the /boot/uEnv.txt file is missing.
Placing a uEnv.txt in /boot doesn't give me the possibility to enable LCD 7 Inch.
/sys/devices/platform/bone_capemgr/slots says the LCD 7 inch is present.
The same problem with 5 inch display on Beaglebone Green.
Has anyone a solution to enable / disable HDMI / UART / I2C what before was done in uEnv.txt.
