LP-AM243: Can't build any SDK library uisng gmake

Hi,

I'm using the mcu_plus_sdk_am243x_08_05_00_24 SDK. I want to rebuild few of the libraries that are provided with SDK and was following the tutorial here. But it doesn't seem to work. I'm on Windows 10, using command prompt to run the gmake.

Please find below the logs when the gmake commands are run:

C:\Users\tonyjosi>gmake -v

Attempt 1:

process_begin: CreateProcess(NULL, C:/ti/ccs1210/ccs/utils/cygwin/mkdir -p obj/am243x/ti-arm-clang/debug/r5f/board/, ...) failed.

Attempt 2:

C:\ti\mcu_plus_sdk_am243x_08_05_00_24>gmake -s -f makefile.am243x enet-cpsw_r5f.ti-arm-clang
process_begin: CreateProcess(NULL, C:/ti/ccs1210/ccs/utils/cygwin/mkdir -p obj/am243x/ti-arm-clang/release/r5f/enet-cpsw/, ...) failed.
make (e=2): The system cannot find the file specified.
makefile.cpsw.am243x.r5f.ti-arm-clang:230: recipe for target 'obj/am243x/ti-arm-clang/release/r5f/enet-cpsw/' failed
gmake[1]: *** [obj/am243x/ti-arm-clang/release/r5f/enet-cpsw/] Error 2
makefile.am243x:560: recipe for target 'enet-cpsw_r5f.ti-arm-clang' failed
gmake: *** [enet-cpsw_r5f.ti-arm-clang] Error 2

I havent modified the Makefiles of any libraries nor made any code changes yet. What I'm I doing wrong here.

Thanks
