is there any body know about interniche tcpip lite?

i downloaded the tcpip lite to my 52233demo board, looks like ethernet working not properly, console is ok(rs232 115200) .

does any body had any idea?

thanks.

I have this working just fine.

You'll need to post bit more info so we can help you. Alternatively, attend on of the MCF5223x Seminars in a city near you. see Alban's post above for more details.

This stack could be compiled on the CW 6.2? it could be used on other Coldfire w/ FEC?

hi,
do you use a gigabit ethernet card on your production system?
if yes, you need to slow it down to 100MB halfduplex.

We will definately need more info.

Do you get a link light on your computer ( does it say the cable is connected )?

I added code in the project to eliminate the need to make any changes to the ethernet settings

on the PC side. So you should not have to force your PC to a speed or duplex setting.

Try the following command at the serial prompt:

ifstat

It gives a ethernet link status. It can also be used to force the link from the ColdFire side.

Try a the iface soft command. This forces a software negotiation.

Code:

/* FUNCTION: ifstats() * * per-iface portion of iface_stats() * * PARAM1: void * pio   - output stream * PARAM2: int ifc      - interface to dump * * EMG - Overloaded function with autonegotiation configuration and soft negotiation * * RETURNS: 0 */intifstats(void * pio, struct net * ifp){ uint16   reg0, reg4, settings; uint8  datarate, duplexe, manual, autodone; char   *cp; datarate = 0; duplexe  = 0; manual   = 0; autodone = 0;  /* get an optional parameter */ cp = nextarg(((GEN_IO)pio)->inbuf); if( *cp ) {  if( strcmp( cp, "soft") == 0 )  {   ns_printf(pio, "\nPerforming Soft Ethernet Negotiation" );       if( SoftEthernetNegotiation( 1 ) )    ns_printf(pio, "\nSuccessfully Negotiated" );    else   {    ns_printf(pio, "\nTry Manual Negotiation" );   }      ns_printf(pio,"\n\n" );   return(0);  }  // We have a parameter  if( strstr(cp, "10") )   datarate = 10;    if( strstr(cp, "100") )   datarate = 100;    if( strstr(cp, "manual") )   manual = 'm';    if( strstr(cp, "auto") )   manual = 'a';    cp = nextarg(((GEN_IO)pio)->inbuf);    if( *cp )  {   if( strstr(cp, "half") )    duplexe = 'h';     if( strstr(cp, "full") )    duplexe = 'f';     }   }   if( datarate || duplexe || manual ) {  ns_printf(pio,"\nSetting ePHY to");   (void)fec_mii_read(0, 0, &reg0);  (void)fec_mii_read(0, 4, &reg4);  if( datarate == 100 )  {   ns_printf(pio," - 100 Mbps");   reg0 |= 0x2000;  }  else  {   reg0 &= ~0x2000;      ns_printf(pio," - 10 Mbps");  }    if( duplexe == 'f' )  {   ns_printf(pio," - Full Duplex");   reg0 |= 0x0100;   }  else  {   reg0 &= ~0x0100;    ns_printf(pio," - Half Duplex");  }    if( manual == 'm' )  {   ns_printf(pio," - manual");   reg0 &= ~0x1000;   }  if( manual == 'a' )  {   ns_printf(pio," - auto");   reg0 |= 0x1000;   }    if( (datarate == 100) && (duplexe == 'f') )  {   ns_printf(pio," - Advertise 100FD");     reg4 |= 0x0100;  }  else  {   ns_printf(pio," - do NOT Advertise 100FD");   reg4 &= ~0x0100;  }  if( (datarate == 100) && (duplexe == 'h') )  {   ns_printf(pio," - Advertise 100HD");     reg4 |= 0x0080;  }  else  {   ns_printf(pio," - do NOT Advertise 100HD");   reg4 &= ~0x0080;  }  if( (datarate == 10) && (duplexe == 'f') )  {   ns_printf(pio," - Advertise 10FD");     reg4 |= 0x0040;  }  else  {   ns_printf(pio," - do NOT Advertise 10FD");   reg4 &= ~0x0040;  }  if( (datarate == 10) && (duplexe == 'h') )  {   ns_printf(pio," - Advertise 10HD");     reg4 |= 0x0020;  }  else  {   ns_printf(pio," - do NOT Advertise 10HD");   reg4 &= ~0x0020;  }    (void)fec_mii_write( 0, 4, reg4 );  (void)fec_mii_write( 0, 0, reg0 );  (void)fec_mii_write( 0, 0, (reg0|0x0200) ); // Force re-negotiate     ns_printf(pio,"\n\n" );    return 0;  }
