# Quickstart to install tools and run unit tests:
$ make -f tensorflow/lite/micro/tools/make/Makefile TARGET="xcore" clean clean_downloads && make -f tensorflow/lite/micro/tools/make/Makefile TARGET="xcore" test_greedy_memory_planner_test || true && pushd tensorflow/lite/micro/tools/make/downloads/xtimecomposer/xTIMEcomposer/15.0.0/ && source SetEnv && popd && make -f tensorflow/lite/micro/tools/make/Makefile TARGET="xcore" test
(add -jN to the final make command to run builds / tests in N parallel threads)
# Background information:
* To start from a fresh repo (this will also remove non-xcore builds and downloads):
```
$ make -f tensorflow/lite/micro/tools/make/Makefile TARGET="xcore" clean clean_downloads
```
* To force xcore.ai tools download from a clean repo:
```
$ make -f tensorflow/lite/micro/tools/make/Makefile TARGET="xcore" test_greedy_memory_planner_test
```
(this will fail to build the test, but if it succeeds because you already have tools it will exit quickly)
* To set up environment variables correctly run the following from the top tensorflow directory:
```
$ make -f tensorflow/lite/micro/tools/make/Makefile TARGET="xcore" test
$ pushd ./tensorflow/lite/micro/tools/make/downloads/xtimecomposer/xTIMEcomposer/15.0.0/ && source SetEnv && popd
$ make -f tensorflow/lite/micro/tools/make/Makefile TARGET="xcore" test
```
* Assuming tools are already set up the following are the most commonly used commands:
```
$ make -f tensorflow/lite/micro/tools/make/Makefile TARGET="xcore" build
$ make -f tensorflow/lite/micro/tools/make/Makefile TARGET="xcore" test
$ make -f tensorflow/lite/micro/tools/make/Makefile TARGET="xcore" < name_of_example i.e. hello_world_test >
```
