Hi lwIP-users!I am sorry, if this mail seems to be "old stuff" for most of you, but I could not find any detailed information about what I am facing here.
I have lwIP 1.3.2 running combined with FreeRTOS on an AVR32UC3A0512. It works fine, but as soon as I start a ping with packetsize 2000(or something similar), the stack seems to crash - meaning, I can't reach the device via IP anymore. As long as I stay below 1536, everything just runs fine.
What could be the option, that I'd have to increase in order to get a "stable" lwIP-stack with packets bigger than 1536(let's say even 65000...)?
Thank you a lot in advance for any single hint(or even a good link to some info about my question)!
Best regards, Dennis
