What is wrong with my Cyclone II configuration circuit?

I just got my Cyclone II PCB back from fab and assembled it. Everything is working correctly except the ASP configuration. My circuit seems to match everything I've found online, including the handbook. MSEL0 and MSEL1 should both be pulled to ground for ASP and JTAG, right?

Both my JTAG programming and ASP seem to work from Quartus. When I plug my byteblaster in to my ASP socket Quartus is able to recognize the PROM, write to it, and verify it. However, when I power cycle the board to program I wrote to the config device does not seem to run.

I have attached the relevant portions of my schematic.

Thanks

    I didn't do any kind of "conversion". There were two files in my output directory, sof and pof. I use the sof file when programming via JTAG, and I selected the pof for ASP.

    Hello

    you can not download .sof file into eeprom.

    as Galfonz says, you need to convert your sof-file but into jic file.

    pof file is the file downloading into EEPROM directory.

    but your circuit does not seem it has the socket for writing eeprom.

    so, in this case you need create jic(JTAG Indirect Configuration File) file.

    this file is downloading file (to eeprom) via JTAG.

    since I don't have time to write detail.

    I give you a hint. see attached file.

    see you.

    Thanks for that reply. I actually do have an ASP programming socket, I just left it off because I didn't think it was relevant. I've attached another screenshot.

    I will also give the jic file a try. Do I put the programmer into JTAG or ASP mode when downloading this file?
