GPIO 4 + 5 on AU335

I'm having issues with GPIO 4 and 5 (pin 9 and 10) on the AU335 model. None of the two pins respond to input, nor do they work as output. They are just permanently pulled high. All other pins seem to work.

Any other AU335 users that can test this for me, please?

    Hi, Stephan Brunner (check other post in May 20, 2021 09:03) has apparently the same issue. I presume this still hasn't been fixed..?

    Thanks Eddi for pointing me in the right direction. It looks like a firmware update should do the trick. Thanks again.

    I'm having this issue too. I updated to the latest stable firmware but that didn't help. It's just 4 and 5. All other GPIO ports work.

    This should be addressed in firmware 8.2.35.4 and newer with the resolution of OS-11529

    "OS-11529: GPIOs 4 and 5 now work correctly on AU335."

    I'm running 8.2.82 and still cannot get those ports to work. Every other GPIO works just fine.
