I2C slave doesn't acknowledge to any address

I need to use I2C SLAVE peripheral on STM32L4.  The problem I am having is that after I set up the I2C peripheral in STM32CUBE and generate the project code, when I use an external I2C master to do an address scan, STM32 doesn't acknowledge to any address.  I have set the slave address to be 0x38 in STM32CUBE.  What have I missed?
