Build error for TensorflowLite number recognition example - tflmrt_lenet

[jayaprasad]

Build is failing for Spresense NuttX SDK example code for TensorflowLite example - tflmrt_lenet associated with external files downloaded from Tensorflow url.

Steps to reproduce the issue.

1. Clone the Spresense SDK source code

$ git clone --recursive https://github.com/sonydevworld/spresense.git

2. Activate the spresense build env

$ source spresenseenv/setup

3. cd to the sdk subdir in source

$ cd spresense/sdk/

4. Update firmware

$ tools/flash.sh -e ~/spresense-binaries-v2.3.0.zip

5. Enable the TensorflowLite example for lenet number recognition using config script.

$ tools/config.py examples/tflmrt_lenet

6. Build the nuttx.spk

$ make

7. Error

tensorflow/lite/micro/tools/make/Makefile:520: *** Something went wrong with the flatbuffers download: Bad checksum. Expected: aa9adc93eb9b33fa1a2a90969e48baee, Got: . Stop.

Hi @jayaprasad,

Unfortunately, TensorFlow does not support building on Windows. You can try to use a different OS or docker.
