Re: can get DHCP IP address, but cannot ping


Hi,Andrew

Are you getting interrupts? If not, that is your problem. You need to find out which interrupt line the ethernet device is using. Read the data sheet for the device.


The board is designed by myself. I connected INTR0 of LAN91C111 to IRL0 of the SH7760 CPU(through a 74AC04 to invert the level). But I don't know how to set the interrupt item in the private data structure. When I found that the private data of "innovator" platform didn't set interrupt item yet, I thougnt maybe it could work without an interrupt item set. And further more I got the DHCP ip address. If it cannot work without an interrupt, why I get the DHCP ip address?
Looking forward to your further help.
