Thank you for answering my question.
I am working on an An61345 code, but it will not work.
Can I use the Slave FIFO mode in the FPGA to load the source that transfers data to the PC?

You can load the source into FX2LP using I2C or USB interfaces. If your FPGA supports I2C slave, you can use it to load the source into FX2LP via I2C interface., (FX2LP has a I2C master)
For I2C boot, please refer: http://www.cypress.com/documentation/application-notes/an50963-ez-usbr-fx1tmfx2lptm-boot-options
