Hi,

When I try to run FreeRTOS + Demo apps on the Keil MCB2100, I get
some strange results that do not occur when I use simulation. In
particular, I get stuck around 0x7FFE252 in the dissasembly and it
just hangs in an infinite loop.

One thing to note is that I am using the H-JTAG debug agent:
http://hjtag.blogspot.com/. Do you think this has anything to do
with my problem?

Beware: uCOSII is not for free !
But still: Linux is far to big :-) As well as eCos.

All the demo applications available in the FreeRTOS.org download should be
usable with the evaluation versions of the respective compilers. This is
the intension anyway.

I originally wrote the Keil port using a beta version of the Keil compiler.
This was an eval version that permitted unlimited compilation, but 16K (?)
limit debugger sessions.

Since then on a different computer I installed the eval version of the
Keil/ARM combo that came with the Luminary Micro development kit. I presume
(but don't know for sure) that this is the same compiler available from
their WEB site. This seemed to compile the project written with the
original Keil tools with no modification, and have the same limitations on
debugger sessions.

Richard.

Hi Richard,

Regarding the Philips LPC2129 (ARM7) RTOS Port for the Keil
Development Tools from http://www.freertos.org/, can I do everything
with the Keil Evaluation tools that are currently available for
download from Keil.com (tools since ARM acquired Keil) Or do I need
a full version?

You get the source from the book, so yeah you have to pay there.
Then its free for 'academic' use, and your original comment
was that this was an academic exercise :)

You do have to pay a license fee for use in commerical products.

Development with GNU-ARM works under both Windows and Linux,
take a look at the appendix in the doc I pointed you to,
and it shows you how to build the tools.

Tom Walsh also has posted build scripts.

The GNU tools work great, and if you aren't prepared to
pay RTOS royalties, why pay for tools, eh!

Check out FreeRTOS too, its absolutely free and they
have lots of examples for the Keil kits.

http://www.freertos.org

However, I've never used it, so can't comment.

If you're still interested in pursuing eCOS, then do a web
search for 'Bruce Perens' Open Source Series' and you'll find
a PDF copy of Anthony Massa's book ...

http://www.phptr.com/series/series.asp?ser35494&rl=1
click on the FREE download link ...

and its down the bottom of the page on the right.

uCOS-II can be used for educational purposes for the cost of purchasing the
book. Any other use requires the purchase of a license.

Have you considered FreeRTOS.org? There are several LPC ports in the
download. I think there are also some files in the download area of this
group.

Richard.

Thanks a lot guys for the responses. I can now remove uClinux from
my options. Another requirement that I have is that anyone should
be able to go and get the source and port for free without any
restrictions, as well as the development tools.

Is uCOS-II free? I thought you had to purchase the book.

Also, will I be needing a Unix-based machine/environment for porting
uCOS-II to Keil MCB2100 (LPC2138)? Ideally, I'd like to do all this
in a Windows environment, using the Keil Evaluation tools. I assume
that I cannot use the evaluation tools because of the 16K
restriction? A full version of ADS v1.2 is also an option.

I'm beggining to think the free GNU tools are the way to go?

Kind Regards

Hi Joe,

The following describes a port of uCOS-II that runs on the LPC2138.

http://www.ovro.caltech.edu/~dwh/ucos/project_AR1803.pdf

the source code is at
http://www.ovro.caltech.edu/~dwh/ucos/

its also in the files section of the Yahoo group.

uCLinux requires more resources than the LPC's have (without
adding more on the external memory bus of the devices that
have one).

I believe there is a port of eCOS, but haven't looked
for it. Try over at www.ecoscentric.com.

You could refer to the site http://www.geocities.com/michaelanburaj where
the port is given..

uC/OS-II is a recommended os for LPC2138. uClinux require atleast 1MB of RAM
I think...
