Hi

When trying to import configuration settings from the EVM, into the Application customization tool, I get the following Exception

-------------------------------

Exception Encountered during I2C Test Read:*** ERROR in FTDI call (I2C_DeviceWrite), status: 2

<type 'exceptions.Exception'>

Traceback (most recent call last):

File "dialogWindow.pyc", line 7638, in test_read

File "hw_interface.pyc", line 408, in hw_i2c_write_no_stop

File "ftdi.pyc", line 314, in ftdi_i2c_write

Exception

-------------------------------

I2C adress set to 000b on S4 (all three off)

I2C adress set to 0x20 in Import Configuration

All S1 switches are On

Exception Occurs when I hit the Test Read button.

What could the cause and solution to this be?

Thanks, Thomas
