Quartus II Assembler Error

Hello,

I have a working Quartus II project with a NIOS II CPU. Due to some issues of the custom board concerning the JTAG chain, I cant use the USB Blaster to upload the software to the board.

Therefore I included the generated onchip_mem.hex in the SOPC builder to compile the software into the design.

While running the assambler I get the following error:
