compile success, but flash fails

[chtfrank]

Hi all,
I tried to fix this problem several days, but I still cannot find the solution. Could someone help me? Thx in advance.
I use the Apple Os, and have installed all the tools required, such as python, make, git and so on. Here are my steps:

1. clone this repo: git clone https://github.com/advaitjain/tflite-micro-sparkfun-edge-examples.git
2. cd into the directory, and type: make TARGET=sparkfun_edge micro_speech
3. during the make process, the arm compiler was downloaded success into the downloads directory.
4. the process finished without any error and the result file was saved at gen/bin/micro_speech, also the libtflm.a.
5. I prepared the OTA bin and Wired bin files according to the steps of the tutorial: https://codelabs.developers.google.com/codelabs/sparkfun-tensorflow#3, but with the offical AmbiqSuite SDK: https://github.com/sparkfun/AmbiqSuiteSDK. Because I found we dont have some tools, such as AmbiqSuite-Rel2.2.0/tools/*. Then I got some size warnings like:
   python tools/apollo3_scripts/create_cust_wireupdate_blob.py --load-address 0x20000 --bin micro_speech_ota.bin -i 6 -o micro_speech_wire --options 0x1
   Header Size = 0x60
   app_size 0x4f69a4 ( 5204388 )

6. Anyway, the wired bin is generated successfully, then I used the python script to flash the Wired bin file to my SparkFun Edge Board, according to the tutorial: https://codelabs.developers.google.com/codelabs/sparkfun-tensorflow#5, but I was failed with no Response error.
7. I think I operated correctly when pressing and releasing the buttons, since I successfully flash the example bin file from the offical AmbiqSuite SDK BSP repo: https://github.com/sparkfun/SparkFun_Apollo3_AmbiqSuite_BSPs/tree/6398086a1a87ddea78274521683ba3ad817bee82/edge/examples/tensorflow_micro_speech , accordind to the SparkFun tutorial: https://learn.sparkfun.com/tutorials/using-sparkfun-edge-board-with-ambiq-apollo3-sdk/example-applications
8. I was surprised to find that the size of the generated bin file gen/bin/micro_speech here (~5.2Mb) is larger than the pre-compiled one in SparkFun_Apollo3_AmbiqSuite_BSPs repo (98Kb), which may result in the warning in step 6 and finally lead to the failure of flashing.
9. I changed to the Ubuntu and Windows, but still cannot flash successfully.

I donnt know how to search the solution, it has taken many days for me to find the answer.
Thx everyone.

build & flash, just run the below

# build & generation binarys
$ git clone https://github.com/advaitjain/tflite-micro-sparkfun-edge-examples.git edge
$ cd edge
$ make examples # build all examples
$ cd gen/bin 
$ arm-none-eabi-objcopy -O binary micro_speech micro_speech.bin
$ git clone https://github.com/sparkfun/Apollo3_Uploader_ASB  ASB
$ cp micro_speech.bin ASB
$ python3 asb.py --bin ./micro_speech.bin --load-address-blob 0x20000 --magic-num 0xCB -o ./tmp_micro_speech.bin --version 0x0 --load-address-wired 0xC000 -i 6 --options 0x1 -b 921600 -port /dev/ttyUSB0 -r 2 -v   # Serial port /dev/ttyUSB0
