Posting a SWI

Chunjian Li

Hi!

I am trying to post a SWI, but with no success. This is what I did:

1. Set it up in the XGCONF. It results in the following codes in the cfg file:

var swi0Params = new Swi.Params();
swi0Params.instance.name = "swiMySwi";
swi0Params.priority = 8;
Program.global.swiMySwi = Swi.create("&MySwi", swi0Params);

2. Put these lines in the code:

#include <ti/sysbios/knl/Swi.h>

......

Swi_post(swiMySwi);

The compilor complains that swiMySwi is undefined. But if I define it in the code, then it complains that it is double defined. I am using BIOS6.32.05.54

Anyone can help?

Isn't it supposed to be defined by the XGCONF?

Add the following to your .c file to include the global definitions from your config file:

#include <xdc/cfg/global.h>

Hi Alan,

That works! Thanks a lot!

Just where am I supposed to find this information? Has diggede into a bunch of documents but couldn't find it anywhere.

Chunjian Li,

I took a quick look through the BIOS User's Guide. While the example sources in that doc do show the file xdc/cfg/global.h being included, I agree that it is not clear that this is necessary.

I filed a bug so that the documentation will get updated to better reflect this:

SDOCM00091088 BIOS UG needs to say that app C code needs #include <xdc/cfg/global.h> to access symbols hanging from Program.global obj
