Description:
   Load executables to various CPUs on the SOC

Usage:

1. Modify "sdkPath" (search for EDIT THIS) to point to the absolute path of the SDK.
    - On windows make sure to use '/' or '\\' as path separator

2. Launch AM64x_GP_EVM target connection in CCS, however DO NOT connect to any CPUs.

3. From CCS Scripting console do (CCS Tool Bar > View > Scripting Console)

        js:> loadJSFile "<path/to/sdk>/tools/ccs_load/am64x/load.js"

4. After successful execution you should see a log like below

        js:> loadJSFile "C:/ti/mcu_plus_sdk/tools/ccs_load/am64x/load.js"
        Connecting, halting, reseting ...
        [r5fss0-0] Loading ... C:/ti/mcu_plus_sdk/examples/drivers/ipc/ipc_rpmsg_echo/am64x-evm/r5fss0-0_freertos/ti-arm-clang/ipc_rpmsg_echo.debug.out
        [r5fss0-1] Loading ... C:/ti/mcu_plus_sdk/examples/drivers/ipc/ipc_rpmsg_echo/am64x-evm/r5fss0-1_nortos/ti-arm-clang/ipc_rpmsg_echo.debug.out
        [r5fss1-0] Loading ... C:/ti/mcu_plus_sdk/examples/drivers/ipc/ipc_rpmsg_echo/am64x-evm/r5fss1-0_nortos/ti-arm-clang/ipc_rpmsg_echo.debug.out
        [r5fss1-1] Loading ... C:/ti/mcu_plus_sdk/examples/drivers/ipc/ipc_rpmsg_echo/am64x-evm/r5fss1-1_nortos/ti-arm-clang/ipc_rpmsg_echo.debug.out
        [m4fss0-0] Skipping load, C:/ti/mcu_plus_sdk/examples/drivers/ipc/ipc_rpmsg_echo/am64x-evm/m4fss0-0_nortos/ti-arm-clang/ipc_rpmsg_echo.debug.out file NOT FOUND ...
        [r5fss0-1] Running ...
        [r5fss1-0] Running ...
        [r5fss1-1] Running ...
        [r5fss0-0] Running ...
        All DONE !!!

5. If any of the logs in step 4 show "fail" or "error" messages then
   check your EVM, CCS, SDK setup, Executables path and try again.

6. To reload without power cycles, repeat step 4 onwards.
