Hy!
Thank you for your answers..
I now trying to port the design to Arria bsed on this reference design:
nios ii ethernet standard rgmii design example (altera wiki)
It uses Arria II GX with TSE in RGMII mode.
So, the problem with ddio is solved. There is an instance of alt_ddio in the design top level.
But I have a problem yet.. Altera recommends to change configure software in Nios II SBT for RGMII mode. There is a link in the altera wiki that goes to
the support question:
how do i change the nios ii triple speed ethernet mac drivers to use rgmii settings? In my case, Im not using TSE_SYSTEM_EXT_MEM_NO_SHARED_FIFO
and I dont know how to configure this..
Im trying:
alt_tse_system_info tse_mac_device[MAXNETS] = {
TSE_SYSTEM_MAC(TSE_MAC)
TSE_SYSTEM_PHY(TSE_PHY_AUTO_ADDRESS, &marvell_cfg_rgmii)};
Could anyone help me on this?
Thank you very much
Emanuela
