### README --- c:/cygwin/home/dhaas/work/cfimage/lwip/arch/coldfire/ ## ## Author: dhaas@alum.rpi.edu 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.
