Cyclone 3 PS configuration problem

Hello, 

 

I am trying to configure a cyclone 3 using passive serial mode and arm9 (in a driver in WinCE6.0). 

 

At first I check if nStatus is low (FPGA in reset) and it is. 

Then, I put nCONFIG from low to high and wait for the FPGA to set nStatus to high ("device ready to receive configuration data"). 

 

At that point I am stuck, as nStatus isn't changing to high. 

 

Can someone help with this topic? Thanks in advance.

Solved. Reason was that not all FPGA voltage supplies were active.
