I successfully finished it today !

I modifiy my stage1 program based on altera-qspi demo program.

There is a function called "system_uinit()" at the end of program.

At beginning I modified program counter before the function executes.Stage 2 program fails.

now I modified counter after the function executes, stage 2 program runs!

i wonder if system_uinit doesn't run,some init functions in stage 2 program fail .
