Verify Fail cause

Hello,

I thought I would share with the forum, atleast one cause of verify fail. Normally thsi is related to some hardware problem. I had a verify fail due to a lack of a non-volatile memory.

In my system that has no NV memory, after I donwload with nios2-download, I would get a verify fail. I added a small bit of on-chip memory and put a small image here that the FPGA would reset to. Afterwards, I would download my real image. The previously verify fail message was gone.

Atleast for users that have no NV in their custom board, this may be helpful when seeing "verify fail"
