GPIO does not read correct values in software for Up sqaured

adarshadesai

Here are the details of the issue:
Hardware : Up squared
1, OS : Ubuntu 16.04
2. using MRAA and python API
3. using GPIO as raw (ex: using Sysfs GPIO 432 for MRAA no 13)
4. without raw =True, it throws error
5. Now, with raw =True and an external pull down resistor connected, it reads constant 0 , but same value correctly detected with Raspberry Pi.
6. Voltage on GPIO changes between 0 and 5v but the software constantly reads 0 from GPIO.
