Well, https://github.com/derekmolloy/boneDeviceTree/blob/master/docs/BeagleboneBlackP8HeaderTable.pdf P8_13 = gpio0_23 P8_24 = gpio0_26 https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/Documentation/devicetree/bindings/input/touchscreen/goodix.txt interrupt-parent = <&gpio0>; interrupts = <0 0>; //interrupts : Interrupt to which the chip is connected irq-gpios = <&gpio0 23 GPIO_ACTIVE_LOW>; reset-gpios = <&gpio0 26 GPIO_ACTIVE_LOW>; Regards, -- Robert Nelson https://rcn-ee.com/ -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
