mubes: That should work, it should not have any pullups / pulldowns by default. Which board are you using? Any chance that the pin is damaged?
<d1b2>
<mubes> It’s our own board, and the whole batch (well, the few we’ve tested) have the same behaviour. This conversation also got going over in #fpga and it’s been suggested it might be being optimised out. Will check that once the dog is walked and errands have been run. Will report back.

How do you detect that there is a pulldown?
<d1b2>
<mubes> We have a 10K pullup on the pin and its sitting at 2v2

<mubes> Just to close this one off, ensuring the pin was pulled into the config and not optimised out fixed the problem (more discussion in #fpga )
