Read and Write 64kB in EPCS

Hi,

I use the epcs memory to store FPGA config data, NIOS software and I will try to use it to store user settings.

To do that, I have a problem : When I try to read or write a full EPCS sector (64kB in my case), I find this is very slow (several seconds).

I call alt_flash_read and alt_flash_write to access it.

Do you have an another mean which is faster ?

Anybody has already use the altera EPCS controller driver ? Where I can have a sample code ?

I thank you for these informations.
