Avalon-MM pipeline bridge won't work with Stratix II devices

I think we would need to see your SoPC topology to help you. If you look at the driver for the TSE MAC you'll see where your error is coming from:

  /* Get the Rx and Tx SGDMA addresses */
   sgdma_tx_dev = alt_avalon_sgdma_open(tse_hw->tse_sgdma_tx);
   
   if(!sgdma_tx_dev) {
      dprintf(" Error opening TX SGDMA\n");
      return ENP_RESOURCE;
   }

Inidication is that the system can't see your SGDMA controller or that it hasn't been informed about it. Are you aware of the changes to the driver which require that you specify to the MAC the names of it's SGDMA controllers before initializing the NicheStack?
