[lwip-users] [lwip]Stack crashing with huge ICMP packets

[Dennis Borgmann]

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
