FX3 is connected to FPGA as below, run the FPGA program and reset FX3, FX3 USB bootloader device can't be shown in Control Center. When disconnect all pins between FX3 and FPGA, reset FX3, FX3 USB bootloader device can be shown in Control Center.
Similarly, separate FX3 and FPGA, burn firmware into FX3. Run the FPGA program and reset FX3, firmware can't be run. Can the output signals of FPGA affect the boot up sequence of FX3? Please kindly advise.
In case FPGA is driving the PMODE[2:0] pins of FX3, boot-up fails. In this case, boot-up the FX3 first and then program the FPGA.
