Binary semaphore in sys/bios

Including that file path fixed my issue.  It also appears that I don't need to include Semaphore.h.  Why is that? 

Thanks,

Will

Hi Will,

Semaphore.h might be included by another one of the SYS/BIOS headers. I'd still include it for completeness myself.

Todd

Will do. 

Thanks,

Will

Hi Todd,

So my computer crashed and I needed to reinstall CCS5 and all packages.  I now have everything up and going except I am now running into the same semaphore issue.  I have the semaphores created in the .cfg file and when I include the global.h file I still get the indentifier ... is undefined.  Is there something that needs to be set up in my buid settings?

Will

Can you attach the .cfg and the source file that is referencing the statically created semaphore.

Todd

Todd,

It seems I can only attach 1 file per post.  Also, I only include global.h b/c I defined the xdc path in the build environment field and then put the total path in the include options.

Second file.

Todd,

  When I look at the global.h file, the #ifdef's are greyed out.  Do I need to define anything to get the global.h file to include the .cfg file?

Will

Will,

What does your include search path look like? I'm asking because you have the following

#include <BIOS.h>
#include <Task.h>
#include <global.h>

instead of

#include <ti/sysbios/BIOS.h>
#include <ti/sysbios/knl/Task.h>
#include <xdc/cfg/global.h>

You also need#include <xdc/std.h> before any other #include.

Did you you add xdc.h before the other includes? Did this resolve the problem.

I added #include <std.h> and it did not fix the issue.  I was not using std.h instead I was using tistdtypes.h.  Is there a diff?

Will

Can you please just export the entire project and post it? You can export it as a archive within CCS.

Here is the zip of my project.

Can you please convert the #includes to the following

#include <std.h>
#include <BIOS.h>
#include <Task.h>
#include <Semaphore.h>
#include <global.h>

to

#include <xdc/std.h>
#include <ti/sysbios/BIOS.h>
#include <ti/sysbios/knl/Semaphore.h>
#include <ti/sysbios/knl/Task.h>
#include <xdc/cfg/global.h>

And rebuild.

Todd,

I received an xdc.tools.configuro error: can't find platform package SADAR

Changing the includes would not have caused this. What else do you change?

Thats all I changed.  I think it is best if I restart from the client_evmc6678l example again and slowely put in my changes.  I think something is very wrong.

I totally agree!
