Downloading ELF Process Failed

Hello daixiwen,

Thanking you for reply,

1. Yes Design Properly Constrained and meet all timing requirements

2. Yes clocks present and at correct frequency.

3. reset signal is also correct.

I have add a three inputs (Start, Load and 8 bit data), coming out from different hardware module.

i am trying to use these there input in my C-code...for holding and further forward these data in UDP format to other terminal.

if i redesign the entire nios-2 Processor with the same configuration and port simple "hello world" there is no issue and nios-2 generate "hello World".

Regards
