In fact, I'm testing some of my GCC code with the beta of Imagecraft. And also using the AppBuilder. This is the first bug I found in ICC ARM. The AppBuilder doesn't set the RTC Clock.

Hi Ezequiel, you find the formulas in the User Manual (Chapter 15, Reference clock divider). For a 60 MHz PCLK you obtain: RTC_PREINT = int( 60e6/32768 ) - 1 = 1830 RTC_PREFRAC = 60e6 - ((1830 + 1) * 32768) = 1792 For the widely used 14.7456 MHz crystal, where you can set CCLK and PCLK to 58.9824 MHz, you obtain RTC_PREINT99, RTC_PREFRAC=0 Cheers, Rolf --- acetoel <> wrote: > > Ups...

Ups... I didn't do that... how can I set it up, if I have a PCLK and CCLK of 60Mhz?

Hi Ezequiel, have you set the prescaler registers RTC_PREINT and RTC_PREFRAC to divide down your pclk to 32.768 kHz?
