I can see the values being updated to the DOR register and the DAC EN is set to 1. However, the output of the DAC is stuck at 0.

I have attached the cubeide settings.

Initialize it as GPIO output and toggle. Does it move?

There are some solder bridges and switches that can affect how PA4 is routed. See user manual.

I didnt realise that the A4 and PA4 are not the same. I checked the schematic after your comment and the problem is fixed. PA4 is connected to A2 pin on the board.
