[lwip-users] RE: [lwip] Use with a microcontroller

[Jason Morgan]

I'll submit change requests to the lwIP tree when he code is fully working,
it may need
an #ifdef _KEIL_ somewhere in it due to the strange pointers that the
C16x/Keil use.

At the moment its sitting on top of my own Ethernet driver that I think I
have to re-write
to make the interface to it more lwIP friendly, once that is done I'll
submit the whole lot.

There is a rather nasty hack joining the two bits together at present.

Hi!

In the CVS version of lwIP that can be downloaded from the homepage, there
is 
an incomplete CS8900A driver in the src/arch/rtxc/netif/cs8900if.c file. It 
currently doesn't work very well - it seems as if there is some memory 
leakage somewhere since it dies after about 10 seconds of use in a real 
network. I would be very happy if someone could check it out to see if there

are any obvious bugs that I have missed.

What are those changes? Ideally, they would be included in the main lwIP 
distribution.
