Hi Jake,

Drop by to ask one question about placing memory in exception vector.

I found that if I place onchip memory for exception vector, cfi flash for reset vector and my program run from ssram, the Nios II system boot up upon reset.

However, if I change my exception vector to ssram (as you said, "exception vector should always be located in RAM of some kind, typically the same RAM you intend to run out of"), somehow, my nios II system cannot boot up.

Do you have any idea wat's going on? I am using Nios II Cyclone II 2c35 board.

Please help
