Hi, Dave and fpgajeg

Thank you for the help.

After I try to configure the two FPGAs, they both work.

(CONF_DONE signal goes high after two FPGAs are configured.)

So now I'm trying to download jic and pof file into the epcs.

(jic and pof files are converted from the sof file)

For jic file, I connect the usb blaster to the JTAG header.

For pof file, I connect the usb blaster to other header for AS mode configuration.

Again, the Quartus II programmer shows me "success" but the FPGA doesn't work.

CONF_DONE signal is low.
