The IAR LPC1768 demo uses hardware with a Micrel PHY. http://www.freertos.org/LPC1768_IAR.html - I think the MAC driver is compatible with the LPC24xx too. In fact the MAC driver for the LPC1768 demo has several improviements over the old LPC23xx demo driver.

Regards.

HI,now interrupt part is ok , MACRXPRODUCEINDEX adn MACRXCONSUMEINDEX are changing when i am pinging ,but uip_process() function failing becouse of the ip address match. shall i do any changes in macros related to ip address excepti uIP_task.c
thanks in avdvance

You must use compatible IP addresses otherwise nothing will work.

RE: LPC2468-Embeded Artist+Eclipse Webserver port

Posted by chacks on September 17, 2009
hi,
i set ipaddress 192.168.1.100 for device and 192.168.1.100 for host pc and use cross cable..i set this ipaddress in uIP_Task.c file. Is there any other changes i need to do for working the ping.
thanks

RE: LPC2468-Embeded Artist+Eclipse Webserver port

Posted by Richard on September 17, 2009
The IP addresses need to be different. Change one of them to 192.168.1.101.

Regards.

sorry i writen 100 by mistake..i given 192.168.1. 102 for host.now when i do ping the interupt is generaing and getting the packet to 2468 controller and indentifiying as ARP paclket but its not returing the packet.i debugged the uip_arpc adn uip_Task.c.what could be teh problem. thanks itws very urgent.

When you debug, what do you see. It gets identified as an ARP, then what?

RE: LPC2468-Embeded Artist+Eclipse Webserver port

Posted by chacks on September 18, 2009
HI,
After identifiying as ARP packet the adress checking condition is faling ( if(uip_ipaddr_cmp(BUF->dipaddr, uip_hostaddr)) ,uip_arp.c).What do you think, am i missing some address configuration somewhere? ur suggetions would be verymuch helpful..i am running out of time.

Do you have the net mask set correctly 255.255.255.0

RE: LPC2468-Embeded Artist+Eclipse Webserver port

Posted by chacks on September 21, 2009
hi, yes i have given the netmask 255.255.255.0 i TCP/P propeties(PC) but in freeRTOS webdemo i set only IP address.where i need to set teh net mask in freertos webdemo.
thanks

hi,
resolved the packet sending issue,it was becouse of the CRC error and i had missed the CRC and PADig setting in the MAC2 register with the macrel phy changes.Thanks for your valuable suggestions.
Now its pinging but its stoping around 200 pings..any idea what could be the issue.

ARM7_LPC2368_Eclipse,contains 4 IP folders in ethernet folder,which one we have to use,uip or FreeRTOS-uip?

Thanks in advance
