RM44L920: Clock Inconsistency - Datasheet: 180 MHz, HALCoGen New Project: 200 MHz

Thanks. Weird that HALCoGen defaults to the wrong frequency. The bootloader project had the same issue, as did a brand new project I created to check.

I have a few HALCoGen-created files I've customized, so it took some time to merge the required changes, but I successfully switched to 180 MHz.

Thanks again!

Looks to be bug in the HALCoGen/v04.07.01/config/RM44L920PGE.cnf configuration file. There are the following lines which appears to specify a frequency of 200 MHz:

VAR.CLKT_PLL1_FREQ.DEFAULT=200.0
VAR.CLKT_GCLK_FREQ.DEFAULT=200.0
VAR.CLKT_HCLK_FREQ.DEFAULT=200.0

Whereas based upon the datasheet for the RM44L920PGE I think the above values should be 180 Mhz.

Thank you for looking into this. I've made notes for next time, backed up the config file and made the appropriate changes.
