RE: [lwip-users] Problem with sending packets with a LPC2368 and lwIP

[Spies, Dominik]

Hi,

It seems to be that my prcessroe is somehow buggy. The reason why packet
do not arrive while in 100Mbit Mode is that these packets are mostly
invalid (driver drops them..). Under Linux i can see the error-counter
increasing in ifconfig.
I have not ethernet analyzer, but my guess is that the device maybe
calculates the CRC-Checksum wrong.
When i run the procesor at 48MHz all works great..

To me it seems you might somehow have mixed half duplex / full duplex
devices.
That would explain why it works with a direct cross link connection...
