I verified that my test code does run when the RCM3000 is plugged into the development board. Looks like a hardware issue on our motherboard. But the fact that DHCP works and Static IP doesn't is really puzzling. Another anomally I noticed is that when no cable is connected to the Rabbit, it hangs at ifpending() waiting for the interface to come up. I plug in the cable it completes. But when I unplug the cable again, ifpending() never changes from a return value of 2, "interface currently up not pending down." Seems inconsistance.

Yes, you might have something connected to pins used by the ethernet port. I think you said it was an RCM3000. I don't think there are any pins used except the data bus (port A). Port A may not be used unless AUX_IO is defined. The rest of the pins are not brought out to the connector (i.e. PE2). You might check /IORD and /IOWR are not connected to anything. There is an option for PD7,PD6 and PD3 and PD2 to have the ethernet signals. I don't think these are enabled by default. Plug the module back in the dev board. I have had similar problems with things like missing pull-ups on external AUX I/O. <Scott ------ | Scott G.

Which version of the compiler did you use? I am using DC v9.1. And I did have a cable connnected to a hub. That would suggest that I have a hardware issue. I'll have to try it out using the Rabbit prototype board rather than my motherboard. But that doesn't expain why DHCP would work and static IP not. Thanks for you help, by the way. And many thanks to the others who have contributed. I really appreciate it.

Well, I think I've stipped about as much off as I can. The below test program will not run. It hangs at the while loop in InitStaticIP waiting for the interface to come up. And I don't see any difference between what I'm doing and what pingme.c does, except for the while loop. And I can take out the while loop and I still don't get a link light on my hub nor can I ping the Rabbit. Go figure. Just cut and paste this code and see. #define TCPCONFIG 6 #use dcrtcp.lib int InitStaticIP(void); void main() { int status; status = InitStaticIP(); for(;;) { tcp_tick(NULL); } } int InitStaticIP() { int status; sock_init(); status = ifconfig( IF_ETH0, IFS_IPADDR, aton("192.168.1.1"), IFS_NETMASK, aton("255.255.255.0"), IFS_END ); ifconfig( IF_ETH0, IFS_UP, IFS_END ); while ( (status=ifpending( IF_ETH0 )) & 1 ) { tcp_tick(NULL); } return( status ); }

Yes, but you are not using the define macros, you are using ifconfig(). From tcp_config.lib: If not defined, or defined to be zero, then no configuration will be defined by this library -- you will need to explicitly define all configuration _macros_ in the main program code before the #use dcrtcp.lib. So if it is 0, it assumes all configuration is via #defines in the main C file. Try it as 6. <Scott ------ | Scott G.

I tried it with TCPCONFIG defined as 6, and it operates the same way. It hangs forever at the while loop waiting for the interface to come up.

I've been using TCPCONFIG of 6 for a long time (and doing runtime config.) Give it a shot. Steve Trigero wrote: > TCPCONFIG is set to 0 per Z-World.

TCPCONFIG is set to 0 per Z-World. Here is a cut & paste from their example: #define TCPCONFIG 0 // Zero means do not do any configuration: expects // all config items to be defined in the main // program.
