Hi there,
I've been trying for a few hours now to get the GPIOs working with the mainline kernel (ARMBIAN Debian GNU/Linux 8 (jessie) 4.5.2-sunxi). According to the board layout photo, I am using PG0, PG1, PG2 and PG3. With the legacy kernel, they export as GPIO1-PG0 a.s.o. accordingly and work perfectly.
So I calculate the GPIO pin number: G is 7th letter, 7 - 1 is 6, 6 * 32 is 192. GPIO192 exports fine, I can set it to output, change the value to 1 but there's no voltage!
Can anyone help me, please?
