We are trying to use this GPIO to enable an output buffer.
I’ve removed the camera from the DTB, so it shows up unused
in /sys/kernel/debug/gpio. If my math is correct, the GPIO
number is 456.
The problem is that immediately on applying power, we get a roughly
1.3 mhz signal out of the pin which doesn’t seem to stop, ever.
This makes it impossible to control the output buffer.
Any idea why this pin would act this way? This happens within a
fraction of a second after power-up, so it’s not like the kernel
or any drivers are doing this.
Thanks in advance,
