AWR2944EVM: How to configure MCAN clock by using sysconfig or other way ?

Part Number: AWR2944EVM
Other Parts Discussed in Thread: AWR2944, SYSCONFIG

Dear Experts 

Here is an issue from your customer may need your help

As shown in image above, We currently use SysConfig version for 1.14.0 and MCU SDK version for 9.0.0.15 to bring up MACN driver on AWR2944 EVM.

We would like to modify default MCAN clock frequency from 80MHz to 40MHz. However, we don't know how to configure MCAN clock by SysConfig tool.

We attempted to modify directly the ti_power_clock_cofnig.c file. but upon rebuilding this project in CCS, the file reverted to its default settings.

  • Hi 

    You can modify "mcan_func_clk" variable in the file "mcu_plus_sdk_awr294x_09_00_00_15\source\drivers\.meta\mcan\soc\mcan_awr294x.syscfg.js".

    Then, the generated ti_power_clock_cofnig will have the modified value.

    Regards,

    Ajay
