Network setup taken over by something

Is that the right thing to do to freeze the code? Or is there a chance of a mod at your end and I hold off?

If your code used "gpiochip1" for "gpio5" let me guess your old kernel
was 3.8.x?

It was using /sys/class/gpio for all gpio’s

/sys/class/gpio in

root@beaglebone:~# uname -a
Linux beaglebone 4.19.94-ti-r42 #1buster SMP PREEMPT Tue Mar 31 19:38:29 UTC 2020 armv7l GNU/Linux

looks almost identical but is unusable

Do what ever you want, 3.8.13 is EOL..

The gpio's got renamed on mainline in 2013 (7 years ago) with 3.10.x..
They haven't changed since.

Then why is /sys/class/gpio unusable when it was useable in 2017? Just wondering…

RobertCNelson · May 8, 2020, 6:53pm

/sys/class/gpio is going to be removed:

It was EOL'ed in 2008, with 2.6.27..

It should disappear some time this year.. (2020)
