Hello. TI engineer

I have wonder that I can't get CPU Tick count.

I found and use Clock_getTicks() function in SYS/BIOS but the function returns always zero.

I set Clock-module in app.cfg using app.cfg file. like this

location(app.cfg) : SYS/BIOS -> Scheduling -> Clock-module settings

I checked "Add clock support to my configuration" and set this

Time base : Internally configure a hal Timer to periodically Clock_tick()

Tick period(us) : 1000

Timer ID : ANY

But Clock_getTicks() returns always zero

plz help me.

Thank you

Thank you for your replay. but I need more information.

I want to calculate to average of transmit time. In order to The wiki, when checking, using break point every time.

I have to several test, over the 10,000 times. I can't check every time using break point. So I want to insert code for auto calculate to average.

If I will insert to the code. I know to get tick time on runtime.

I need your help.

Thank you.

Hi,

What core are you testing on? Are the other cores halted or free running while you are running the test?

Instead of using TIMER_ANY, can you set it to a unused timer like Timer 0 (just for debugging, you can change it back afterwards). Can you verify that the "Enable Clock Manager" box is checked in the BIOS options page (screenshot below).

After you rebuild/load your application, run it for a while and then pause it. Open the register view for the Timer you selected above (should look like the screenshot below):

cntlo/cnthi contain the timer count and should have changed while the core was running. Can you post a screen show of these registers?
