I'm trying to configure P9.13 on the Beaglebone AI as an input pull up, but am not having any success. In the System Manual <https://github.com/beagleboard/beaglebone-ai/wiki/System-Reference-Manual#p9.11-p9.13> it lists P9.13a as not being bound to a GPIO port, but P9.13b is bound to GPIO6_12. This is the device tree overlay I'm using <https://github.com/PocketNC/BeagleBoard-DeviceTrees/blob/pocketnc-ai-test/src/arm/am5729-beagleboneai-pocketnc-pro.dts#L56> with line 56 showing how I'm attempting to configure P9.13b (and P9.13a the line above it). Am I doing something wrong in my device tree overlay? I've had success configuring many other pins, but P9.13 is giving me trouble for some reason.
I'm testing it a couple ways: 1) with sysfs echo 172 > /sys/class/gpio/export cat /sys/class/gpio/gpio172/value 2) with libgpio gpioget gpiochip5 12 Both return a value of 0, when I'd expect it to be 1 (I don't have anything wired to it). Any idea what I'm doing wrong? -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
