a problem about flash programmer

I had these problems too and i could nearly always solve them with these steps :

open the quartus project and then open the sopc

go to the spoc builder setup ( Menue -> file -> sopc builder setup )

make sure that you have entered the path to the sopc target board you have created with mk_target_board. it is okay to enter the path where your created path by mk_target_board is located.

again ... you have to check this on *ALL* computers where you wish to deal with the ide with thios board. these settings are not stored within the qpf, but they are stored inside the windows registry ... (altera please change this !)

my hint nearly all problems with jtag, flash, ide ... were solved by doing exactly what altera describes in the application note you mentioned.

i am not shure if you have done the same mistake i did the first time i created a nios2 target. the project you create by mk_target_board is not the target for your application, it is only for programming with the ide.

verify that your flash is a CFI compliant type.
