Dear Embedded folks,
I am looking for guidance with selection of a hardware development
platform and tools for a new project. The task is essentially to embed an
Ethernet router in an existing system, which will consume some network
traffic (TCP/IP) and forward the rest. As a first phase, we would like to
get a working hardware platform for code development; later we roll our own
hardware based on the selected controller. I have been surveying platforms
that provide Ethernet connectivity and sufficient horsepower to process
level-2 packets; the toughest part has been finding appropriate
development tools.
From what Iâ??ve learned here and elsewhere, the Freescale ColdFire (e.g.MCF5282) or an ARM-based device (e.g. AT91RM9200, Samsung S3C4510B) are
suitable controller choices. At this point I am leaning towards ColdFire
based on praise of the architecture.
I have been evaluating the NetBurner MOD5282
(http://www.netburner.com/products/core_modules/mod5282.html) . While it
is a nice, compact package, it appears ill-suited for this project: the
debug interface is via the network connection, making it difficult to test
custom network drivers â?? a straight-ahead BDM debug interface seems more
appropriate.
The debug interface is completly seperate from the normal packet processing flow.
With simple function call you can even make the debug interface dual homed so it does not
conflict at all with your normal packet processing.
If you want to do low level packet processing we have provided modified versions of the
debug ethernet driver that support that functionality.
This allows you to step through the packet processing with the debugger.
Just submit a support request.

CTO Netburner.
