Nios 2 IDE download verification error

I 've just posted the same problem in onother topic .. see topic (http://www.niosforum.com/forum/index.php?act=st&f=17&t=1777)

The messages I get are:

Downloading 00005000 ( 0%)      (-> this is internal ROM)

Verify failed                                 ( -> ERROR )
Leaving target processor paused

The failure occurs while verifying the content of EPCS! At address 0 of EPCS there is FPGA configuration data. Behind that, a short loader is placed in my custom design, which of course is compiled and linked to address 0, but placed in a quite other location in EPCS. So there must be a verify error, when software data is compared against FPGA configuration data. And all data in EPCS are correct. The system runs.

Has anybody an idea how to force debug to run ?
