I installed Ubuntu 14.04 on Raspberry Pi Model B+ and everything worked fine. However I found out that the pins are not functioning. I tested it with a multimeter, and even the Vcc pins (5v, 3.3v) do not have the required voltage.
Is there a way to get it working?
---Edited--- I was trying to connect the Raspberry pi to an arduino via RS485 network. Raspberry Pi is the master and the arduino is the slave. I connected a Max485 ttl to RS485 module to the Raspberry and found out that it didn't work. Then only I checked the voltages just to make sure. Turns out even the Vcc pins don't work. I'm not sure whether this is because I'm running ubuntu 14.04 instead of raspbian
