3.3.1. Configuring Slave FPGAs with Different Configuration Files

To configure the slave FPGAs with different configuration files, connect the nCEO pin of one slave FPGA to the nCE pin of the next slave FPGA in the chain. When the first slave FPGA completes configuration, the slave FPGA pulls the nCEO pin low to enable configuration for the next slave FPGA. This process continues until the last slave FPGA in the chain is configured. You can leave the nCEO pin of the last device unconnected or use the pin as a user I/O pin.

Figure 5. Mixed Chain Topology with Different Configuration FilesThe following figure shows the connections required to configure slave FPGAs with different configuration files using the FPP scheme.
