Hello,

 

I love armbian and I know the gpio is working on the directory /sys/class/gpio/gpio(number) but I really need to use armbian + the gpio module gpio-sunxi

 

modprobe gpio-sunxi

ls /sys/class/gpio_sw/

normal_led  PA10  PA13    PA18  PA20  PA6  PA9  PC2  PC7     PG7  PL10

PA0        PA11  PA14    PA19  PA21  PA7  PC0  PC3  PD14  PG8  standby_led

PA1        PA12  PA15    PA2   PA3   PA8  PC1  PC4  PG6     PG9

echo 1 > /sys/class/gpio_sw/standby_led/data

echo 0 > /sys/class/gpio_sw/standby_led/data

 

is it possible to active this module with kernel 3 or 4, if yes where is possible to enable it ? in the kernel config ?

 

 

From the title: pi zero H2

 

So then it's placed in the wrong sub-forum. Do you plan to use BSP 3.4 Kernel or 4.x mainline? (depending on this I'll move it in the right sub-forum). 

 

In mainline GPIOs are handled either by sysFS (deprecated) or libgpiod. If you plan to have something 'future-proof'  you should consider switch to a libgpiod based approach. 

 BSP 3.4 Kernel with  sysFS (deprecated)  give me the option to active modprobe gpio-sunxi ?

https://github.com/armbian/build/blob/53acd5be582d53b87d8cfd01f35633b159b4ca3f/config/kernel/linux-sun8i-default.config#L2014-L2016

 

with the 3.4 kernel you can use GPIO-sunxi and sysfs:

https://github.com/armbian/build/blob/53acd5be582d53b87d8cfd01f35633b159b4ca3f/config/kernel/linux-sun8i-default.config#L1979

 

but 3.4 is an old kernel, and if your board doesn't do any hw accelerated videodecoding I would go for a recent 4.14.y kernel with armbian next were we still offer sysfs and additionally you've the opportunity to use libgpiod.
