Here is my UART output: U-Boot SPL 2014.04-00014-g47880f5 (Apr 22 2014 - 13:23:54) Could not probe the EEPROM; something fundamentally wrong on the I2C bus. Could not get board ID. Could not probe the EEPROM; something fundamentally wrong on the I2C bus. Could not get board ID. Unknown board, cannot configure pinmux.### ERROR ### Please RESET the board ###
On reset, the same message repeats. I'll probe the I2C bus and see what I can find.
