我对AN84868 FX3配置FPGA的问题

关于FX3配置FPGA的8868问题
1）在AN848 68中，如果FPGA已经由FX3配置，它将切换到从FIFO模式。这是否意味着原来的代码只能配置FPGA一次？是否有可能拆分通道，一个通道只用于配置。如果该信道从主机获得数据，则意味着配置是预期的，并且FX3GPIO切换到配置。
2）如果主机没有在AN848 68发送数据到FX3，那么GPIO引脚是否是三态的？
3）将GPIO引脚将三态当RESET引脚保持活跃。
以上的问题来自我的新计划：配置kintex-7 FPGA大师BPI模式供电然后FX3可以重新配置FPGA只要主机发送配置数据，FX3还应该在Slave FIFO模式使FPGA与主机之间的数据传输在不配置tion. BPI和FX3 SPI将共享一些FPGA引脚。如何避免冲突？
谢谢您。

  My questions on AN84868 configuring FPGA by FX3
1) In AN84868, if the FPGA has been configured by FX3, it will switch to slave FIFO mode. Does this mean the original codes can only configure FPGA for once? Is it possible to split channels, one channel is only for configuring. If this channel get the data from host, it means the configuration is expected,and the FX3 GPIO switch to configuration.
2) If the host have not send data to FX3 in AN84868, will the GPIO pins be tristate?
3) Will the GPIO pins be tristate when the reset pin is hold active.
The above questions come from my new plan: configuring kintex-7 FPGA by Master BPI mode on powering up and then FX3 can reconfigure FPGA as long as the host sends configuring data, the FX3 should also be in a slave FIFO mode to enable the transfer of data between FPGA and host when not in configuration. BPI and FX3 SPI will share some of FPGA pins. How to avoid conflict?
Thank you.
