"make tree V=hexagon_Debug_dynamic_toolv82_v65 " give a misleading error message.
C:\Qualcomm\Hexagon_SDK\3.5.2/build/make.d.ext/hexagon/defines.min:36: *** Cannot find Hexagon Tools at C:/Qualcomm/HEXAGON_Tools/8.2.07. Environment variable HEXAGON_TOOLS_ROOT can be set to override the default location. Stop.
In fact , you should use "make tree V=hexagon_Debug_dynamic_toolv83_v65" (v83 instead of v82).....
