C5505 RTC Write Access

Jrvanho

I am using the 32KHz RTC clock with the PLL to generate the SYSCLK. When I run the example CSL_RTC_Example_Out project, I notice that none of the writes to the RTC registers actually take place.

Is it possible to write to the RTC registers when using the 32KHz clock for SYSCLK? Or do I need to do something special to make that happen?

I am running version C55XCSL-LOWPOWER-2.10.00.00 and CCS 4.2.3.00004

Thanks in advance!

Hi,

I believe you can write to the RTC registers if you have a proper clock fed to it. 32KHz clock should be ok

I first configure the PLL for 100MHz and then attempt to write to the registers.

I am able to write to all of the other registers on the DSP. I am even able to read from the RTC registers.

Cheers,
