Load_getGlobalSwiLoad() and Load_getGlobalHwiLoad() doesn't work anymore

Other Parts Discussed in Thread: SYSBIOS

In my code, I monitor the task, swi and hwi load with methods Load_getCPULoad(), Load_getGlobalSwiLoad() and Load_getGlobalHwiLoad(). I have up till now used SYS/BIOS 6.31.04.27, where all three methods worked fine. However, with the latest SYS/BIOS 6.32.02.39, HWI load is always zero and SWI load is always 100%.

Hi Niklas,

There was a change in 6.32 to default the Load.hwiEnable and Load.swiEnable to false. Can you check these settings and set them to true?

Hi Todd

Thanks for the tip. Setting both to "true" did the trick, I now gett the correct HWI and SWI load.

However, I'm not completely satisfied with this solution. Setting hwiEnabled or swiEnabled to true also requires that libType is set to custom, and that sysbios need to be recompiled. Instrumented or NonInstrumented doesn't work anymore.

With libType set to custom, you also get all your sysbios object files in a subfolder called "src" in your project, which is not where I want them, since I have multiple targets in my project (with different compiler settings). So, how do I change the output folder of sysbios?

There is an undocumented BIOS configuration parameter, BIOS.libDir, that you can use to set the directory where the custom SYS/BIOS library is placed.

You may want to use something like this:

BIOS.libDir = "myCustomLib_" + Program.build.target.suffix + "/";

If you're using the IPC product, you'll need to do something similar for the ti.sdo.ipc.Build module:

Build.libDir = "myCustomLib_" + Program.build.target.suffix + "/";
