MCU-PLUS-SDK-AM263X: makefile:168: recipe for target 'post-build' failed

Hi,

  I am working through the getting started steps. 

https://software-dl.ti.com/mcu-plus-sdk/esd/AM243X/08_05_00_24/exports/docs/api_guide_am243x/GETTING_STARTED_BUILD.html#autotoc_md40

I imported the project  /examples/hello_world

I am able to build load and run hello_world_am243x-lp_r5fss0-0_freertos_ti-arm-clang.out

All steps but the last one work correctly, it fails with the error message pasted in the code section below. 

gmake is installed and the path is correct

C:\ti\mcu_plus_sdk_am243x_08_06_00_43\tools\boot>gmake --version
