I'm running out of free time to pursue this. If you could, pls continue with similar tests for the other GPIOs. There are 36 GPIOs that are usable (0 to 35). And I've determined those above were the most likely to work, based on my understanding of Kirkwood SoC GPIO implementation.

You could try to test the rest of the GPIOs (excluding the ones already defined in the NSA320S DTS).
