from the qII5.0 ,i just meet so many times,when i make a custom board project,then i start the SOPC Builder,it flash suddenly ,but the SOPC Builder don't show.
i read the ug_nios2_flash_programmer.pdf,my make target board command is:
mk_target_board --name=test-board --family=cyclone --clock=50 --index=1 --buffer_size=4096 --epcs=U4 it create success!
so i open the quartusII project,and select my cyclone device EP1C6Q240C8,and start the SOPC Builder ,but something is wrong that i don't see, the builder start fail!
it becomes strange ! i do by the same way, the SOPC Builder works. so i think whether altera can present some wrong message when occur such thing?
