What is the Raspberry Pi OS version used here?

BTW, it is good to have libelf-dev and libfidi1-dev for avrdude. libftdi-dev (libftdi-0.x) is rather old and not updated for quite some time.

[merlinblack]

Raspbian GNU/Linux 10 (buster)

Thanks for the libelf-dev and libftdi1-dev tip :-)

[merlinblack]

Hmm 10 is a bit old, I'll upgrade and see if that helps. I'm guessing it will. :+1:

[mcuee]

Maybe you can still keep your Raspberry Pi OS version but you can try to build libgpiod from source codes (1.5.x branch or newer branches). https://git.kernel.org/pub/scm/libs/libgpiod/libgpiod.git/

[merlinblack]

Upgrading to raspbian 11 did the trick. Compiling a newer libgpiod most likely would have worked too.

Thank you for your help ☺️
