GPIO doesn't work

[Артем Силиванчик]

Hi!

I try to use GPIO on BananaPi M5 board. But interface doesn't work.

 

Armbian 23.05.1 Jammy with Linux 6.1.30-meson64.

 

/boot/armbianEnv.txt:

verbosity=1
console=both
overlay_prefix=meson
fdtfile=amlogic/meson-sm1-bananapi-m5.dtb
rootdev=UUID=d099eb25-cf52-43fb-b826-535b9109637f
rootfstype=ext4
overlays=w1-gpio
usbstoragequirks=0x2537:0x1066:u,0x2537:0x1068:u

Have any ideas?

"w1" refers to the 1-wire protocol... it is just one application of GPIO, but it is not what you need for GPIO

 

I wanted to use GPIO for the first time yesterday in orangepi zero, but was not successful... I will keep trying today.
