sharvin-vittappan commented 3 weeks ago

Hi, I am trying to build tflm lib for hexagon. make command issued: export HEXAGON_TOOL_VER=8.5.08 export HEXAGON_ROOT=/location of hexagon SDK/Hexagon_SDK/4.5.0.4/tools/HEXAGON_Tools export HEXAGON_CPU_VER=v66 export HEXAGON_TFLM_LIB=/path to library/hexagon_tflm_core.a make -f tensorflow/lite/micro/tools/make/Makefile TARGET=hexagon OPTIMIZED_KERNEL_DIR=hexagon microlite

I get an error as: tensorflow/lite/micro/tools/make/Makefile:653: *** Incorrect OPTIMIZED_KERNEL_DIR: The optimized kernel directory: tensorflow/lite/micro/kernels/hexagon does not exist.. Stop.

You will want to add OPTIMIZED_KERNEL_DIR_PREFIX=${TENSORFLOW_ROOT}third_party to your build command. Examples of build commands for the Hexagon target can be found here.
