I am working on the RH850 F1KM S1 controller. CAN is working fine when it is configured with Main source and Emergency clock as module clock(pclk). When it is configured with PPLL1OUT clock as module clock(pclk), CAN is not working. I am using xinclk for the baudrate generation. what could be the reason?
What is your main clock freq, and PLL freq?
Main clock is 8mhz, PLLOUT is 80mhz
Hi JimB
Did you get anything?
Do you use the Smart Configurator to set the clocks?
How have you configured them ?
Thanks for your response. i am still trying, But not able to solve it yet. I have configured through smart configurator . Please let me know the solution for this.
Hello and apologies for the delay.
So it works with this configuration:
and not with this ?
Are you using a custom board or F1KM-S1 Starter Kit ?
Hello Supporter,
We also facing same kind of issue in RH850 F1KM S1. We are configuring PLL1CLKIN as MAIN_OSC , NR, MR, Divider values in such a way to get PLL1OUT 80 MHz and CPLL1OUT as 120MHz.
The following registers is showing EMCLK configurations. But we are not configuring EMCLK in Autosar.
These registers are getting default values. It seems the configuration is not done for these areas. Kindly provide the possible causes which affects these clock initialisation
