DIO inputs and outputs not working

Hi to all of the support team,

I've got a RevPi Core S and a DIO module, connected everything together and I'm trying to make the inputs and the outputs of the DIO module to work... without success until now.

The OS is updated, the firmware is updated. The module is configured in Pictory. I can see it with piTest. I can write values in the different registers (offsets) and they stay.

BUT, the problem is that outputs don't change whatever I try !!! I tried push-pull mode - nothing. I tried high-side switch - again nothing.

What I'm missing ?!?

Hi

What do the status Bytes of the modules (eg. OutputStatus) report?
Is the power for the outputs wired correctly (see pinout in documentation?
Are all LEDs on the DIO green?
