+To prove this on a newly-flashed Feather Huzzah running Micropython 1.9.3, 
+it should be possible (on a posix-compliant platform with adafruit_ampy installed) 
+to `cd test/scripts` then run `./upload_feather_huzzah_micropython_put.sh` to 
+synchronize relevant files to the filesystem of the huzzah, reset the huzzah then 
+connect using `screen /dev/ttyUSB0 115200` before running the above commands.
+
+Micropython hosts require a micropython repository alongside
+the Adafruit_Micropython_Blinka repository. For circuitpython, 
+the repository is expected to be called circuitpython_2.2.3. 
+In each case, the matching version should have been checked out from github
+and `make` needs to have been run in the `mpy-cross` folder. This provides a tool 
+to make bytecode-compiled .mpy versions of all .py files before upload so that 
+tests can be achieved within the limited memory available on many target platforms.

 ## Comments
 
 There are reference routines in `test/scripts` like `upload_feather_huzzah_micropython_put.sh` which execute a selective bytecode-compile to .mpy format and an ampy upload for CircuitPython/Micropython on esp8266, or `upload_pyboard_micropython_cp.sh` which selectively bytecode-compiles and synchronizes files with cp to the CIRCUITPY or PYBFLASH disk mount for stm32 and samd21 platforms.
