RTOS/TMS320F28377S: Timer in SYS/BIOS

Hi Jegan,

Can you show the code that is creating the timer and the actual timer function also?

Can you look in Tools->ROV->Timer to make sure the timer is there? Are you providing the timer to the BIOS Clock module (and calling Clock_tick)? If not, what timer is it using?

It might be easier to attach your entire .cfg file. I'd like to see other system configuration.

I am not using clock module. I use the timer to create swi's.

The .cfg file is attached here for your reference.

config.cfg

Thanks. I'll take a look at it. Was there anything interesting in ROV->Timer? Can you include a snapshot of it?

Sure. Note: I want to run the processor at 200MHz

Also, I would like to know, why the cpu clock freq is set to 2.5MHz by default in BIOS? How to override this?

The default is 2.5Mhz because that is the defaults out of reset.

You override it by making configuration changes to the Boot module.  I think you're doing that already in your .cfg file:

Boot.SPLLIMULT = 40;
BIOS.cpuFreq.lo = 200000000;
Boot.SYSCLKDIVSEL = 1;

Is it possible that something else is also triggering the same GPIO?  Seems like you have made the right configurations with respect to the system clock and Timer.

Jegan,

Did this get resolved?
