I have been working on implementing a port to the atmel ATMega128 and
I have noticed that sending UDP packets does not work (the transferred
data is always 0).
A look into the code reveals that in uip.c, the address of uip_appdata
gets set incorrectly.
Somewhere around line 1159 the code needs to be changed:
--- uip_appdata = &uip_buf[UIP_LLH_LEN + UIP_IPTCPH_LEN];
+++ uip_appdata = &uip_buf[UIP_LLH_LEN + UIP_IPUDPH_LEN];
Can anyone confirm this? The only UDP app I'm using for the moment is
the uip's resolv, which seems to work either way. But I'm starting to
write an UDP app, so this one makes me wonder.
I have not tested it, but from reading the code it seems this is a bug
in uIP 1.0. (Strange that it didn't cause more havoc!)
Thanks,
