Tool/software:

Dear TI experts

I am using  bissc_diagnostic_single_channel_am243x-lp_r5fss0-0_freertos_ti-arm-clang example from  motor_control_sdk_am243x_09_02_00_09 

I am having problem to change PRU-ICSSG core clock in sysconfig to 300Mhz in this example. It was greyed out. Is this intentional?

I have another IP running in the some ICSSG module that requires 300Mhz core clock.

Thanks

Alan I

    Hi Alan,

    There is a bug in the BiSS-C Sysconfig module, so it is not allowing the other core clock value to be selected instead of 200mhz

    In Biss-c Sysconfig meta file (motor_control_sdk_am243x_09_02_00_09 \source\.meta\position_sense\bissc.syscfg.js), it is hard coded to 200mhz.

    You have to comment out "coreClk: 200*1000000," line then SysConfig will allow to select other pru core clock values.

    Thanks & regards,

    Achala Ram
