These files are a port of lwip to coldfire (specifically the MCF5272 with
|
|
on-board FEC) under the Nucleus OS. Nucleus is pretty generic so it should be
|
|
fairly easy to port this to any other embedded OS. Nucleus memory managment
|
|
is not used. It is assumed you have a working malloc (which at least
|
|
long-word aligns memory).
|
|
|
|
The compiler used was Diab 4.3b. You will almost certainly need to change
|
|
cc.h for your compiler.
|
|
|
|
IMPORTANT NOTE: If you use the fec driver for a different processor which has
|
|
a data cache you will need to make sure the buffer descriptors and memory
|
|
used for pbufs are not in a cachable area. Otherwise the fec driver is
|
|
guarrenteed to malfunction. The 5272 which this was written for does not
|
|
support data cache so it did not matter and malloc was used.
