Build Project error

946 Views

I am trying to program my FPGA (DE2-115) to use Ethernet as an IO medium. In Nios (13.1), I have two projects "pmd_tcp" and "pmd_tcp_bsp". pmd_tcp_bsp generates the bsp and builds the project without throwing any errors. However, when I try to build the project for pmd_tcp, I get the following error:

obj/default/tse_my_system.o:(.data+0x44): undefined reference to `marvell_cfg_rgmii'

collect2.exe: error: ld returned 1 exit status

make: *** [pmd_tcp.elf] Error 1

The program was initially written on Nios 12 while I am using Nios 13.1 if that means anything.
