Programming the fpga and spiritual flash

Recommended Posts

Hi, I'm doing my final project for the practical engenier on the papilio duo.

Yesterday I started checking the board, and I couldn't mount the bit file on the fpga.

The butterfly loader said the process is done, the rx led from the ftdi blinked for some time, but the code doesn't seem to be loaded, I tried it on my Spartan 6 evaluation kit, and it worked.

Is there something I'm missing?

Thank you.

The FTDI FT2232H USB chip has two serial channels, A and B.  The FPGA programming software needs to talk to Channel A which is connected to the FPGA JTAG pins.  My understanding is that the RX and TX LEDs are on Channel B which talks to ordinary FPGA I/Os, so if RX is blinking it means your programming software is talking to the wrong channel.

 

See if Felix's suggestion works.  If it doesn't, please indicate what OS and software you're using to program the FPGA.
