Stratix II GX configuration

Hello,

I have a problem with the configuration of a Stratix II GX FPGA (EP2SGX130).

I am using AS-programming with EPCS64.

When I use a "standard" .pof-file the configuration procedure stops after a while (nSTATUS getting low) and starts again from the beginning (auto restart after error is enabled). CONF_DONE does not reach high-level at all. The Quartus software does not give any error-message when programming the EPCS64.

When I use a compressed .pof-file then all works perfectly and CONF_DONE is getting high.

Does anyone know, what the problem with the uncompressed images could be or how to debug it?

I am using a custom board for the FPGA.

On an Altera Development Board with the EP2SGX90 (and also EPCS64) it works with the compressed and the uncompressed pof-files.

Thank you for your help!

Johnny.

    Thank you aka_fpga_wizard,

    in my case CONF_DONE doesn't transition to high-status at all. And I am using Quartus II version 7.2.

    But maybe there is still a bug in the software?!?

    Anyway, I am using compression know but keep your link in mind for the case I get configuration errors again.

    Thanks again,

    Johnny
