I have a ZC706 board running Petalinux 2015.2.1. I am trying to interface to an MPU-6050 interial device over the I2C bus. Due to the lack of PS accessable PMOD connectors on the board my HW eng routed the I2C bus through the PL. Nothing was done to the signals, it is just a route to PMOD 1 - J58.. He tied the I2C interrupt to GIC 0. I can't get the I2C driver to talk to the MPU.
This is the modified i2c1 entry from system-top.dts:
