ChibiOS/RT RTOS ported to LPCXpresso (LPC1114)

Hello,

Some of you may be interested in a free embedded RTOS for the LPCXpresso. ChibiOS/RT version 1.5.4 includes support for the LPC1114 and a demo for LPCXpresso (with or without base board). The LPC111x support also includes a serial buffered driver, a GPIO ports driver, configurable clocks initialization and startup code. More drivers will be added in next releases.

The download is available here:

https://sourceforge.net/projects/chibios/files/

If you are curious to see how the Cortex-M0 performs compared to other ARM devices you may find this interesting (performance data is at the end of the reports, scroll down):

http://chibios.sourceforge.net/benchmarks.html

Note that it actually seems to perform *better* that ARM7 controllers in THUMB mode. Soon also the LPC13xx will be supported and added to the benchmarks page.

Just a status update,

In the latest version 1.5.5 support and demo for the LPC13xx family has been added.

Performance data for the LPC1343 (LPCXpresso) has been added to the benchmarks page: http://chibios.sourceforge.net/benchmarks.html
I hope this can help comparing LPC11xx and LPC13xx.

Thanks for helping. I tried moving the OS folder into C:\nxp\lpcxpresso_3.2\ directory but still got errors - doing MAKE from the command worked though. Don't worry about it for now - perhaps someone will get it to work and post here.

I tried your suggestion - I have the same paths in my system (default install). This is what I got:
The odd thing is that I see those .mk files in my [B]ChibiOS_1.5unstable[/B] folder (located in My Doucments).

Doh, may be it is the space in "My Documents" that creates problems, try putting the OS directory into a path without spaces. I am out of ideas :-)

I tried deleting everything and importing again - same problem.

There is some good news though. When I use MAKE (I mistakenly thought it was make.bat) in the command window, I noticed that it created a ch.hex file as shown below:
I download the hex file to LPCXpresso (with base board) using [B]Flashmagic [/B]and it appears to be executing main.c - RGB Led's are flashing etc.

Here is a screen of main.c in LPCXpresso - there are several errors, unresolved includes and syntax error (on [B]static WORKING_AREA(waThread1, 128)[/B])

Ok it seems that the OS demo works then, it is just a project setup problem into the IDE.
Please could you try the following procedure ?

- Open the project properties.
- Open "C/C++ Build" and select "Environment".
- Create a variable PATH and put "C:\nxp\lpcxpresso_3.2\Tools\bin;C:\nxp\lpcxpresso_3.2\Tools\arm-none-eabi\bin;C:\nxp\lpcxpresso_3.2\msys\bin" as value (without quotes).
- Try to compile.

Please verify you have the same paths into the system.

Using make.bat, it seems that there no errors, --version gives this.

Wait a moment, why make.bat? it should be the normal GNU make, make.exe in windows. It is located in C:\nxp\lpcxpresso_3.2\msys\bin do you have this path in the PATH variable?

I unzipped everything - this is the contents of the directory. Thanks for your help, Giovanni.

It looks ok, I can only suggest to delete the project from Code Red and follow the importing procedure again (http://chibios.sourceforge.net/html/article__eclipse2.html).
Make sure to keep any other project in closed state when compiling the demo.

If you are able to compile from the command line then the problem must be in the project imported into code red.

I don't understand this part of the error:

Quote:

make all
'test' is not recognized as an internal or external command,
operable program or batch file.
A subdirectory or file . already exists.
The system cannot find the path specified.
ECHO is off.

A question, do you have other projects into code red IDE? if so try to close them all, then "clean" the OS demo and then try building it again, it is possible Eclipse tries to build multiple projects.

Make a small test, are you able to compile from the command line? from within the demo directory just give the command "make".

If it does not work then give the command: "arm-none-eabi-gcc --version" and post the result here. It should print "arm-none-eabi-gcc (Code Red/Red Suite 2/2009_01) 4.3.3".

I think you have two GCC toolchains installed that have the same name arm-none-eabi- (is it codesourcery ?), the other one is picked first in the path and does not support the Cortex-M0.

If this is correct, try renaming the other toolchain directory while compiling.

When building the demo project under LPCXpresso IDE, I get this error message. Any suggestions?

The project is not setup to build in the LPCXpresso IDE as is.

I suggest reading the documentation here:
http://chibios.sourceforge.net/html/article__eclipse2.html

It is a guide for building the demo examples using Eclipse. It is basically the same when building under the Eclipse based LPCXpresso ide

Bruce is correct, all the demos are pure makefile projects but can be imported into Eclipse using the procedure described in that article. Of course it works even with the LPCXpresso IDE (I use it too) but does not require it.

It is also recommended to add the LPCXpresso binaries path (usually C:\nxp\lpcxpresso_3.2\Tools\bin) to the system path variable, that way the compiler can be located by make.

You'll need the latest (trunk) version to get the M0 port. I think that's 1.54 at this point.

I don't see the folder with the cortex M0, I download the version 1.4.2, but I dont see the folder LPC1114 with LPCXpresso
