thank you for your fast reply,
it is right, that i use the quartus web edition without a valid nios license.
i try to program another sof file into the flash without time limit (generate with quatus 9.0 web edition)
--> the error message does exist no more
BUT: after building the checksum -> the nios time limted license stoped and the program does not be send to the flash
additional : the "<>.flash" - file was generated
do you there is another possibility to program the flash ?
sorry, but what dou you mean with "nios -e type"
thanks
