Hi,
I have design a PCB which want to use FX3 to configure FPGA. I have followed application notes AN84868, but the FPGA in my FPGA is Spartan 3E. When I connect to USB 2.0 port, FPGA can be configured successfully. However, when I connect to USB 3.0 port, the configuration will be failed. I have checked PROGRAM_B and INIT_B pin, both trigger well. The running result indicates DMA buffer is filled with FPGA configuration data, but no data is transferred FPGA. Could you guys help me think of some possible reason?
Thanks a lot
Zoe Wang
