#16 Support for MCF5372

[Frank Glaser]

Environment:
FNet 2.0.0 ported to MCF5372, without any OS
Cross compiled with gcc 4.2.3 (WinXP SP3 + Cygwin 1.7.17-1)

Used Protocols:
ARP, UDP with IP Fragmentation

Network Configuration:
One target (MCF5372) and one Windows Host, both configured with static IPs.

Attached You will find all files based on FNet 2.3.0 and the used fnet_user_config.h.

\fnet_stack\cpu\mcf\fnet_mcf_isr.asm See fnet_mcf_isr_inst.c

Open points:
CPU timer, flash, cache implementation
ISR: extract vector number to allow calling the timer handler

[Andrej Butok]

May not accept the changes:
fnet_mcf.h - cause of used way of registers definitions. Should be used existing aproach.
fnet_mcf_isr.c - assigned only to FEC interupt??? It MUST be interrupt independent.
fnet_mcf_isr_inst.c - should be universal.
fnet_mcf_config.h - may not be changed. All changes of default parameters must be in the fnet_mcf5372_config.h.
