Speed problem with EPCS

Hello all together, 

 

i have an problem with the EPCS. 

After I load my Software with the Flashprogrammer in the EPCS and restart my Device, it takes around 25s till my programm starts. 

I measured the CONFIG_DONE and the DCKL-Lines at EPCS. 

The result is, that the Cyclone2-Device loads the FPGA-Design-File correct (with correct Speed), and then transfer the Software with very low Speed from EPCS to SDRAM (200 KB in 20s). 

 

The Hardware-Platform is fully tested (an other Design functions without this problem). 

The Flashprogrammer-design works too (the same design works with another project). 

 

Extra_delay option in EPCS-Source-class is set to "0". 

 

Here my IDE Infos: 

 

Quartus 5.0 SP1 

NIOS2 5.0 SP1 

 

I hope anyone can help me!! http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/smile.gif

DO NOT use v5.0. You should use v5.1 sp1, or the latest v6.0 . Altera had improved the speed.
