Hello cetic, no you&#39;re quite right. My modified HAL-driver wasn&#39;t the problem. In fact the compiler didn&#39;t take my modifications into account at all. The problems I had was caused be the PLL alone. I also installed some modified flash-drivers, but these didn&#39;t update the firmware_ROM. Sorry I can&#39;t be of more help there http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/sad.gif

A little thing to try:

You say your flash-drivers work. Can you build an old fashioned Nios I application with a fully working GERMS-monitor? Because - I believe anyway - that would be a work around to writing to the flash since the NIOS II IDE seems to be generating flash-files too. When using the old Nios I we could burn the flash by using the command nios-run followed by the flash-file we wanted burned to flash.

I do not know if the above solution will work ....remember I&#39;m pretty new at this http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/wink.gif but hopefully some of the experts can verify this idea.

Hope you can make it work!

Regards

Goon
