clock monitor reaction test

Other Parts Discussed in Thread: HALCOGEN, TMS570LS3137, CCSTUDIO

Hello,

I am trying to test ESM group1 channel 11 (Clock Monitor - interrupt). I have seen that in file sys_selftest.c generated by halcogen there is function checkClockMonitor() which apparently tests this ESM channel. I have tried to use this function but it gets stuck in

while((systemREG1->GBLSTAT & 0x1U) == 0U)

{
} /* Wait */

so the oscillator flag is never set.

Do you know how I can test ESM group 1 channel 11?

Regards,

Francis.

Hi Francis,

Is it possible for you to send the project, we need to look at System module configurations before you call checkClockMonitor() function.

Also which Device is it?

Hello Prathap,

I am using a Hercules board with TMs570LS3137 revision C. I am trying to create CCStudio project that I can send you (we do not use CCStudio for developing, just a makefile system with TI compiler 5.1.6)

If you can tell me what configuration I need in order to have this function working maybe I can find the problem. I am configuring PLL1 180 Mhz...

Regards,

Francis.

Hi Francis,

No configuration in particular, The function should work. I could not reproduce the issue at my bench with 180 MHz.

Are you using HALCoGen Startup files? Send me system.h, system.c, selftest.c, sys_main or which ever file you are calling checkClockMonitor() function. That should be sufficent, Also send me the makefile so taht I can replicate the build configurations.

Hello Prathap,

No, I am not using HALCoGen startup files. I can see that after disabling the oscillator to cause a oscillator fail

systemREG1->CSDISSET = 0x1U;

in register CSVSTAT I have value 0xFB, what means that oscillator is still valid (bit 0 is set). But I can also see bit 0 set in CSDIS register (oscillator disabled).

So I guess that the problem is that even though oscillator is disabled, it does not become valid. Would you mind to help understand why?

Regards.,

Francis.

Hi Francis,

Just to Confirm, did you use the checkClockMonitor() function from HALCoGen as is.
Below three lines are needed for this test.

/* Enable clock monitor range detection circuitry */
systemREG1->CLKTEST |= 0x03000000U;

/* Backup register GHVSRC */
ghvsrc_bk = systemREG1->GHVSRC;

/* Switch all clock domains to HF LPO */
systemREG1->GHVSRC = 0x05050005U;

Hello Prathap,

Yes, of course I used those 3 lines. Basically I copied the function into our code.

Thanks,

Francis.

Hello Prathap,

If I create a CCStudio with our start sequence would you mind to help to find out why this test is not working for us?

Regards,

Francis.

Are you looking for more help on this?

Hello Prathap,

Sorry that I forgot to set this as answered. I did it now. I think that the problem was that I was using a revision A of the TMS570. But I got it working with revision C.

Francis.
