CC3200 trying to get the cpu load using sysbios.utils.load

Younes Hamdaoui

Other Parts Discussed in Thread: CC3200SDK, CC3200, SYSBIOS

I am trying to retrieve the CpuLoad from the CC3200 board, so I ve got a ccs app based on the tcp_socket example provided in the CC3200SDK.

I have added

var Load = xdc.useModule('ti.sysbios.utils.Load');

to the ti_rtos_config rtsc cfg file and rebuilt everything, and also added the path to the xdc and bios packages.

When I call uint32_t load = Load_getCPULoad();

I've got the following linker error:
unresolved symbol ti_sysbios_utils_Load_getCPULoad__E, first referenced in ./main.obj

As I don't have a deep understanding how all those dependencies are managed I don't really understand which libraries or includes are missing.

Does anyone faced the same problem ?

What version of TI-RTOS are you using?

Hi Younes,

That error occurs when you have not used the Load module in your .cfg file:
var Load = xdc.useModule('ti.sysbios.utils.Load');

Maybe you can attach the .cfg file you are using.

Hi Janet,

This is the .cfg I'm using :

var UARTMon = xdc.useModule('ti.tirtos.utils.UARTMon');
var Memory = xdc.useModule('xdc.runtime.Memory');
var Load = xdc.useModule('ti.sysbios.utils.Load');
var BIOS = xdc.useModule('ti.sysbios.BIOS');
var LoggingSetup = xdc.useModule('ti.uia.sysbios.LoggingSetup');
var Task = xdc.useModule('ti.sysbios.knl.Task');
var Timer = xdc.useModule('ti.sysbios.hal.Timer');
var Clock = xdc.useModule('ti.sysbios.knl.Clock');
Load.hwiEnabled = true;
Load.swiEnabled = true;
Load.taskEnabled = true;

Is something missing to use the Load module ?

Thanks a lot,

Younes.

Hi Younes,

I'm not able to reproduce the linker error you are seeing. Can you try importing the stairstep example and building it? You can find it through the TI Resource Explorer:

You can compare stairstep.cfg with your .cfg file. You don't need to configure the Load module directly, since you are using LoggingSetup. There are LoggingSetup configuration parameters that configure the Load module for you. You can see this in stairstep.cfg.

Best regards,

Janet

Hi Janet,

The problem was coming from misconfiguration.

Thanks a lot for your fast answer.

Younes.
