Error ip header checksum

hi slacker,

i disabled the udp checksum from nios ii to pc, but when i send a udp-message to nios ii from pc i alway get an incorrect checksum. it always says it is 0x0000 in stead of e.g. 0x4f7a. is this because lwip disables all ip-options!? and it works fine. everything works the way it should, but it is just something that bothers me...

cheers,

danny

Danny,

I suggest you either re-read Slacker&#39;s post or follow my advice on learning how to help yourself.

A UDP checksum of 0 is not incorrect as Slacker said it means NO CHECKSUM. As UDP checksums are optional this is perfectly OK.
