https://software-dl.ti.com/mcu-plus-sdk/esd/AM261X/10_02_00_15/exports/docs/api_guide_am261x/CCS_SETUP_PAGE.html

Install all requirements mentioned in requirements.txt (Location - ind_comms_sdk/mcu_plus_sdk/requirements.txt)

/*Navigate to mcu_plus_sdk folder and then run the following command*/
pip install -r requirements.txt

Steps to run the Profinet example:

Overview- The Profinet demo on AM261x-LP supports execution from external flash i.e XIP. So to properly run the example we need to program the sbl_ospi_mcelf and application image(.mcelf) into flash using Uniflash tool, then set boot mode to OSPI, and then we can see successful run logs. Follow the below steps:

1. Open CCS and import the Profinet example in project explorer

2. Build the project and make sure profinet_device_demo_am261x-lp_r5fss0-0_freertos_ti-arm-clang.mcelf and mcelf_xip image  is generated correctly, see the success log below. If there are any error see this post.

3. Take LP-AM261x, put it in dev boot mode. Then, open the Uniflash GUI tool and select 

SBL - sbl_ospi_multicore_elf.release.tiimage (location - ind_comms_sdk/mcu_plus_sdk/tools/boot/sbl_prebuilt/am261x-lp)

Application profinet_device_demo_am261x-lp_r5fss0-0_freertos_ti-arm-clang.mcelf (location - CCS workspace)

XIP Image - profinet_device_demo_am261x-lp_r5fss0-0_freertos_ti-arm-clang.mcelf_xip ((location - CCS workspace)

Click on load image.

4. After loading is successful. Disconnect the power cable and Change the boot mode pins to OSPI Boot mode

5. Next power on the device and open the UART COM port to see success log of Profinet example:
