I've recently been tasked with getting a Dallas Semiconductors 1-wire thermalcouple working with a Microzed running petalinux. First of all, is this possible? or is the PS PMod port hardwired to interact with other interfaces? I've tried editing the device tree to include the 1-wire device at the gpio pin I've plugged it into, as well as activating the 1-wire linux drivers in the kernel config menu, but this does not seem to be working. The drivers load, but do not detect and register any device.

Thanks for your response. I've got a pull up resistor in place already. As for "out with the scope", do you mean an oscilliscope? What would I be looking for, and what does that have to do with getting Linux to recognize the device?
