Hello,
I too have been looking for viable replacements for the HC12D60A
processor. Has anyone used the CF M5282lite eval board from quadros??? They
offer a kit that bundles an eval board with a limited RTOS kernel and a GNU
compiler. I have downloaded the compiler, but didn't get the kit yet has
anyone had any experience using this compiler??? or any of the GNU
compilers for the coldfire MCU????
Thanks,

Good day Oliver, In regards to your queston: > very interesting. Do you have also a speed comparison? Sadly, no. I have not done any type of code profiling between the HC12 and CF. However, I may do some in the next few weeks. If I do, I will post the results.

I had a look at Coldfire and noticed that it has DRAM support, I hope
that is better than Freescale PowerPC for MPC850. There are tables you
have to load, and I found the only way to get that table was to ask
Freescale to create one for you for the particular DRAM I was using.
I also found CodeWarior difficult with this PPC. It was overly
complicated and not practical to interrogate the map file to see how
memory resources are being used.
If I was persuaded that Coldfire was as easy to implement as MC9S12 with
Cosmic C I might keep it in mind for a future application.

Good day Andrew,
I have been using CW with the Coldfire family for about 5 years and have
been extremely satisfied with the device and the CW tools. I find it to be
as easy as the HC12, but with superior debugging and resource (SDRAM
interface, QSPI, Ethernet, etc) capabilities. However, the hardware design
can be a lot more complex (SDRAM interface, BGA packages, etc) depending
upon the Coldfire device used... Using the Coldfire 5213, I found the design
difficulty to be no worse than that of a HC12 design.
In regards to your MPC850's DRAM issue, this is not the case with the
Coldfire... At least not the ones I have ever worked with. In my Coldfire
experience, the (S)Dram setup was merely a combination of hardware
interfacing (connecting various address lines correctly as well as byte
strobes, etc) and various register setups. It is true that the Coldfire
documents do contain (S)Dram setup tables, but these just detail various
(S)Dram interfacing combinations (hardware connections, etc)... and not
"tables" that one has to actually load.
As for CW difficulty, I have had no issues.... quirks yes... but issues no.
Certainly CW is somewhat intimidating, but once you get accustomed to it, it
works very well. I would suggest that you download a Special Edition
version of CW (low capacity free version) from Freescale and evaluate it
with an inexpensive Coldfire development board to see how you like/dislike
it, as CW tends to operate differently depending upon the target used.
Cheers,
Sam

Hello All
There was mention of Freescale not giving enough importance to the
ColdFire like not setting up a forum/list for it. Looks like Freescale
listened and have set up a forum for it, just yesterday.

Jay,
You are correct...we do listen. Thanks for posting the link to the new
Freescale ColdFire forums. Actually, the forums were in planning
before all these "Freescale not giving enough importance to ColdFire"
thread started. It was hard to keep quiet about it, but it was planned
to go along with more good news...
I would like to point out that Freescale introduced two new ColdFire
families today, see release:
http://biz.yahoo.com/bw/060404/20060404005598.html?.v=1
Also, product pages:
The MCF5223x (x=0-5) family of devices are single-chip solutions with
an integrated Ethernet interface (FEC) and an on-chip Ethernet
Physical Layer (PHY). Here is a link to the superset device:
http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=MCF52235&nodeId62468rH3YTLC00M98090
The MCF5222x (x=1,3) family of devices are single-chip devices that
feature an integrated USB host and On-The-Go (OTG) controller. Here is
a link to the superset device:
http://www.freescale.com/webapp/sps/site/prod_summary.jsp?code=MCF52223&nodeId62468rH3YTLC00M98145

Is the 10k unit pricing not too far from the 1k unit pricing? It's good
to see that the pricing appears close to the NE64...
Though Freescale needs to work on getting everything ready for release
when they announce stuff (the new chips aren't listed in the ColdFire
overview docs yet either).. From Freescale's announcement at
http://www.freescale.com/files/abstract/overview/TSP_8435_LP.htm:
Available now for the MCF5223x family are the M52233DEMO, a
cost-effective and highly functional demonstration board for quick and
easy application development,
www.freescale.com doesn't seem to know anything about the M52233DEMO
product... zero results on the search page, both keyword and Part
Number.. Interesting definition of available now...
Though one cool thing to note is that it appears that the pinout of
the 80TQFP matches that NE64.. which is nice, in that it'll make
migrating to ColdFire a lot easier.. I was afraid that the announcement
of common pinouts for 8bit and 32bit controllers would skip the 16bit
controllers, but that doesn't appear to be the case...
There is one minor change in that the MC5223x 80TQFP doesn't have the
XFC pin, but I think people can live w/ removing components from their
board. :)
