Flashing code to sparkfun edge #2574

Closed h-tye closed 1 month ago

h-tye commented 1 month ago

Hello, I am trying to upload example code to the SparkFun Edge and have been following these instructions: https://codelabs.developers.google.com/codelabs/sparkfun-tensorflow/#4 I ran into issues at step 4 when trying to execute:

make -f tensorflow/lite/micro/tools/make/Makefile TARGET=sparkfun_edge micro_speech_bin

After a lot of digging, I found this on issue #341:

The following command will build all the examples:

make examples

and it did not throw any errors. However, I am unsure what it actually did. Has it completely built all the necessary binary so that I will be able to flash it to the board? Any help would be much appreciated.

@h-tye

If you are using the https://github.com/advaitjain/tflite-micro-sparkfun-edge-examples repository, then the make examples command builds all the example applications. The binaries for those applications are located in the gen/bin/ directory relative to your cloned repository root.

As for uploading a binary to your SparkFun board, you can try the instructions starting at step 5 (https://codelabs.developers.google.com/codelabs/sparkfun-tensorflow/#4) or refer to any instructions given for your specific board at the SparkFun website.

Please note there is no official TFLM support for this platform.

Thanks so much. Just one more question, in the gen/bin/ directory, the binaries are labeled "hello_world.d" and "micro_speech.d" rather than .bin. In the instructions(https://codelabs.developers.google.com/codelabs/sparkfun-tensorflow/#4), .bin files are used, do you know if .d files can be used interchangeably with .bin? Or is this just something I'll have to experiment with?
