Tool/software:

Hi there,

I am using motor control sdk 9.2.0.9. Please refer to mck plus sdk included therein: motor_control_sdk_am243x_09_02_00_09/mcu_plus_sdk/docs/mcu_plus_sdk_am243x_manifest.html
The mcu is having the version: 
MCU+ SDK 09.02.00 BSD-3-Clause Source and Binary N/A Location [as installed]/*
Obtained from Texas Instruments


MCUSDK-12117 bug should have fixed in MCU plus SDK 9.2.0 according this page: https://software-dl.ti.com/mcu-plus-sdk/esd/AM243X/09_01_00_41/exports/docs/api_guide_am243x/RELEASE_NOTES_09_01_00_PAGE.html
citation:

MCUSDK-12117 Setting the ICSSG1 clock frequency affects the ICSSG0 clock frequency SOC 9.0.0 onwards AM64x, AM243x Added ICSS cores init in SBL

However in single chip servo demo using motor control sdk 9.2.0.9 (which includes MCU plus sdk 9.2.0),  MCUSDK-12117 manual fix is still needed. 
In other words, System_init_modified() must be called in order to make EtherCAT work. I tried System_init() and EtherCAT failed to work then. 
/* ESL_OS_init(); */
System_init_modified();



Could you confirm if MCUSDK-12117 is fixed in motor control sdk 9.2.0.9?

Best regards,
Jinlong

    The issue is not fixed as needed for reference design in 9.2 release, it will be fixed in next release(10.x).

    sorry for marking MCUSDK-12117 as fixed in 9.2 release.

    Thanks & regards,
    Manoj.
