Hi, I’m experimenting with GPIO on X86J4105. Using sysfs is deprecated, replaced with libgpiod. Examples I see online work OK, but not for me! Hence this post. So trying:
$ sudo gpiodetect
gpiochip0 [INT3453:00] (80 lines)
gpiochip1 [INT3453:01] (80 lines)
gpiochip2 [INT3453:02] (20 lines)
gpiochip3 [INT3453:03] (35 lines)
Works OK, But:
$ sudo gpioget 0 0
gpioget: cannot find line ‘0’
gpioget: cannot find line ‘0’
obviously does not, but as I said, it works for other people!
Any advice, suggestions much appreciated, all the best.
Check the output of dmesg | grep gpio to see if there are any errors or warnings related to GPIO.
Thank you for your reply @liaifat85.
dmesg | grep gpio returns nothing at all gpio related.
I have installed libgpiod-devel.x86_64 and libgpiod-utils.x86_64, maybe I need to install something else?
