Thank you for your answer.

I understand that i have to export the 2nd Port of the onchip memory.

My first problem is:

I dont know how to store data with nios in the on chip memory. Is there anywhere a documentation what commands can be used in nios. For example i cant even find a documentation for the IOWR command used for toggling LED´s or something.
