Flash EPC64, slow to program

Hello,

We use on our board EPC64 flashes to store the pof

file for the stratix 2.

This take about 10 minutes to upload the pof;

This is slow.

When the sof is uploaded with the same usb blaster, it takes 5 seconds,

so clearly the flash is the limiting factor.

As we will move to stratix 3 which are two times bigger, I expect bigger pofs as well,

and I guess that programming the flash will take ages.

Is Altera aware of this problem, and will they propose an equivalent to the EPC64 (easy to integrate) but much faster ?

    A CPLD with fast flash might help.

    Try SST, their erase and AAI program will faster.

    But you will need to convert some SPI command to each side.

    Or, add a socket on EPCSx, then re-program them in a factory flash programmer will also faster.

    If you're trying to find a solution that only 3 sec, multi-OS support with network access..

    There are not many choice.
