Building Coldfire 52235 demo - Eclipse, how?

Posted by M Beronius on January 22, 2009


Finally, I am at the point where I am trying my first steps with FreeRTOS!

But, I run in to problem immedialetly, in that I can't even build the demo example;

I have FreeRTOS 5.1.1, gcc version 4.3.2 (Sourcery G++ Lite 4.3-54)

Since I normally don't use Eclipse, I simply tried to 'make' from within the folder where the makefile is, and I got some path errors, which might be expected. (see output below)

So I instead tried using Eclipse, where I selected the workspace as suggested in the guide, and I set the root dir for FreeRTOS, I hit refresh on the project, and 'Build All' and .. and .. Nothing! No output window or anything. Nothing gets build and no errors...
Since I never used Eclipse, I don't know how to carry on from here.

Or should I instead try to make a new makefile, and forget about Eclipse?

Output from make at command line;
~/projects/FreeRTOS/Demo/ColdFire_MCF52233_Eclipse/RTOSDemo $ make

Its complaining it cannot find portmacro.h, which it is expecting to find in ../../../source/portable/GCC/ColdFire_V2. This path is relative to the location of the makefile.

I've just taken a look the files are in the correct places relative to each other, so I'm going to guess that you are building under Linux. Is this right? If so then the capitalization of the path is wrong. For a start Source should be with a capital S. Try checking the case of the letters. If this is the problem report it to Richard.

So simple, yet so easy to miss!

There's a few other issues with building this under linux;

As noted, 'source' needs to be 'Source' on line 206 in portable.h.

Make file;
m68K-elf-as should be m68k-elf-as
m68K-elf-objcopy should be m68k-elf-objcopy

Many thanks for your help! (I Will report this to Richard)
