List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Sun, 12 Mar 2017 13:57:18 -0000 I experience problems to enable the ADC line of my BBB. Apparently, in FreeBSD 10, the ADC lines would have been enabled by a = sysctl call: sysctl dev.ti_adc.0.ain.0.enable=3D1 On FreeBSD 12, this gives: sysctl: unknown oid 'dev.ti_adc.0.ain.0.enable' I thought, perhaps the driver has not been loaded into the kernel, but: kldload ti_adc =20 >>>> kldload: can't load ti_adc: module already loaded or in kernel Question: What do I need to get the ADC working with FreeBSD 12?
