The an84868 configure fpga in slave serial mode. after cinfiguration FPGA can communicate FX3 in slave fifo mode in this example. If I hope to make a modification on the mode of FPGA configuration to slave selectmap32, hoping fpga can still communacate FX3 in slave FIFO32 mode after configuration. I have read an87216,it shows me how to use FX3 in master mode and may solve the configuration problem . It uses state machine in gpif2, and slave fifo also needs the design of state machine in gpif2,will they confilict?

You cannot have both the state machines running at the same time. May be once you are done configuring the FPGA, you can load the slaveFIFO gpif.h file.

Do you mean that i should download two different firmware to FX3 at different time?

Can I use FX3 to configure xilinx fpga in slave selectmap32 mode and communicate with FPGA in slave FIFO mode after configuration

No. I mean you can have 2 different gpif2config.h files in your firmware. One for FPGA configuration and the other for SlaveFIFO.You can load one of these files using the GpifLoad() API.
