I have two GPIO pins that I'd like to be high during the boot process. These pins, GPIO 44 and 23, are connected to LEDs through some circuitry. I've managed to set those pins when uBoot runs, but they are reset during the boot process: as soon as the linux kernel starts these pins are pulled low. After linux finishes booting I install a device tree overlay and can resume control of the pins.
How can I prevent these pins from being cleared? Is this done by the linux kernel itself or some driver? How do I start looking for the code responsible? (I also posted this question 3 days ago but it hasn't appeared in the relevant group). -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
