hello guys, i did a port of lwip to our custom mpc5200 board. transmission runs quite fast so far, but i still have stability problems. i am not sure if this is a lwip related problem or if it comes from lower levels, e.g. fec driver, interrupt handling or even dma problems.
with my lwip app i constantly transmit 1000Byte long packets. this works quite well up to a certain point. sometimes i even transmit 3GB of data until it starts to stuck, but sometimes it hangs after 10MB. in my ethernet transmit function i did some sanity checks, doing so showed up that lwip sometimes tries to transmit packets larger than 1300Byte which shouldn't be the case. i am not sure where this behavior comes from i already did a lot of research but nothing brought any improvement. anybody already had similar problems or just got a tip where to do some more research. thank you very much in advance. best regards, andre _______________________________________________ lwip-users mailing list [email protected] http://lists.nongnu.org/mailman/listinfo/lwip-users
