Error when loading a new FPGA Version on Cyclone IV GX

Hello, 

 

I have a major problem sometimes when i try to load the Flash Memory with new FPGA Version on Cyclone IV GX. 

 

When I load the FPGA Flash it is stop in the middle with Error Message & the J-TAG is Unconnected without access. 

 

It is a major problem because Then I can't access to the J-TAG or to FPGA or to Flash. 

 

The old version charged properly. 

 

I have this major problem sometimes. 

 

Can U help me to fix this problem A.S.A.P ? 

 

Best Regards

Hi Avi, 

 

Can you post the exact error message that you get when programming the device? Could you also post the FPGA type and Flash type, and the settings of the board, like AS-mode, etc?
