Load UFM separately

Hello,

I'm about to program MAX II UFM independently. We are using the UFM to store a security number. I want to give users a convenient means of changing parameters stored

in UFM, and using Quartus II to make a pof file is not comfortable, also I don't want to ship users the design part of the project.

Is it possible to give users already compiled file for CFM and possibility to change just UFM part, and to load UFM & CFM separately? Must I port the jam player? How?

What did I miss?

Thanks,

Victor.

    Separate reading and writing of CFM and UFM to/from a file is supported in Quartus Programmer, so there's at least a way. Altera stand-alone-programmer could be used as well.

    Otherwise you need a custom JTAG programming option, or have to write the data by the MAX II design itself.

    Hi there,

    I'm wondering if there is a way to program just the UFM on a MAX II device from .mif or .hex file using the the programming JTAG interface and more specific without using the Quartus compiler to reconfigure the .pof file?

    Thanks in advance.
