RESOLVED -- Problem with I2C_EEPROM example on STM3220G-EVAL board

I am trying to run the IC_EEPROM example on the STM3220G-EVAL evaluation board, and I cannot get it to work.  Jumper JP24 is not installed, so I believe it is writable.  When I run the example, the LCD display shows the error message "Communication ERROR! Try again after resettting the Board", but of course, that doesn't help.

The program hangs in the first call to sEE_WriteBuffer, immediately after sEE_Init. Looking into that function, I see it is timing out and calling the user callback function that indeed results in the above error message.

The IOE (I/O Expander) works properly, so it doesn't seem to be a problem with the I2C, per se.

Any ideas?
