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
