Re: Problem working (using nichestack TCP/IP - nios 2 ) tutorial

Hello

I have been following the tutorial https://www.altera.com/content/dam/altera-www/global/en_us/pdfs/literature/tt/tt_nios2_tcpip.pdf

I used the Nios II Ethernet Standard Design Example of stratix IV https://www.altera.com/support/support-resources/design-examples/intellectual-property/embedded/nios-ii/exm-net-std-de.html

My quartus version 15.0 and the example was for version 12.0

I have only changed the tse_mac (Triple Speed Ethernet) from the Ethernet_system.qsys subfile to support the Stratix IV board

in the top level code of the example there are those components

.tse_mac_conduit_connection_mdc (enet_mdc),

.tse_mac_conduit_connection_mdio_in (mdio_in),

.tse_mac_conduit_connection_mdio_oen (mdio_oen),

.tse_mac_conduit_connection_mdio_out (mdio_out),

.tse_mac_conduit_connection_ref_clk (clkin_125),

.tse_mac_conduit_connection_rxp (enet_rx_p),

.tse_mac_conduit_connection_txp (enet_tx_p),

.flash_tcm_address_out (fsm_a),

.flash_tcm_data_out (fsm_d),

.flash_tcm_read_n_out (flash_oen),

.flash_tcm_write_n_out (flash_wen),

.flash_tcm_chipselect_n_out (flash_cen)

when I compile the example it says it did not find those components in the main (eth_std_main_system)

I will appreciate if someone guides me what do those components represent, I assume the tse part is because I changed that part in the Qsys file but I want to know what each one represent so I can put on the changed part

whats mdc, mdio, ... etc?

I have managed to make it work but when I use Putty Talnet connection in port 30 it does not work as it shows that it sends packets but nothing is received please advise
