[beagleboard] AM3358 on 300 MHz

2015-09-21 Thread Mark Ruys
I'm confused how the BBB can run on 300 MHz. The BeagleBone has a AM3358 processor, and according to http://www.ti.com/lit/ds/symlink/am3358.pdf, it supports 600, 800, and 1000 Mhz, not 300 MHz. Still, using tools like cpufreq-set, you can set the frequency to 300. The power usage drops indeed

[beagleboard] AIN4 erroneous

2014-05-06 Thread Mark Ruys
On two different BBB's (latest revision) I've noticed strange behavior of AIN4. I have a TMP36 (analog temperature sensor) running on 3V3. Vout measures 712 mV ((712 - 500) / 10 C = 21 degree C). If I attach Vout to any AIN* except AIN4, I can use the BB and read out 712. So the ADC is working,
