Damien George cdaec0dcaf tools/pydfu.py: Support DFU files with elements of zero size.
Instead of raising a ZeroDivisionError, this tool now just skips any
elements in the DFU file that have zero size.

Andrew Leech 07f181a216 Revert "tools/pydfu.py: Respect longer timeouts requested by DFU dev..."
This reverts commit 4d6f60d428.

This implementation used the timeout as a maximum amount of time needed for
the operation, when actually the spec and other tools suggest that it's the
minumum delay needed between subsequent USB transfers.

c0rejump 6db5cede06 tools/pydfu.py: Clean up syntax, update comments and docstrings.
Some parts of code have been aligned to increase readability.  In general
'' instead of "" were used wherever possible to keep the same convention
for entire file.  Import inspect line has been moved to the top according
to hints reported by pep8 tools.  A few extra spaces were removed, a few
missing spaces were added.  Comments have been updated, mostly in
"read_dfu_file" function.  Some other comments have been capitalized and/or
slightly updated.  A few docstrings were fixed as well.  No real code
changes intended.

Dave Hylands c932639063 tools/pydfu.py: Fix regression so tool runs under Python 2 again.
Under python3 (tested with 3.6.7) bytes with a list of integers as an
argument returns a different result than under python 2.7 (tested with
2.7.15rc1) which causes pydfu.py to fail when run under 2.7.  Changing
bytes to bytearray makes pydfu work properly under both Python 2.7 and
Python 3.6.

Damien George 4f25a8b6a4 tools/pydfu.py: Improve DFU reset, and auto-detect USB transfer size.
A DFU device must be in the idle state before it can be programmed, and
this requires either clearing the status or aborting, depending on its
current state.  Code is added to do this.  And the USB transfer size is now
automatically detected so devices with a size less than 2048 bytes work
correctly.

Andrew Leech a2703649ea tools/pydfu: Workaround stdio flush error on Windows with Python 3.6.
There appears to be an issue on Windows with CPython >= 3.6,
sys.stdout.flush() raises an exception:

    OSError: [WinError 87] The parameter is incorrect

It works fine to just catch and ignore the error on the flush line.  Tested
on Windows 10 x64 1803 (Build 17134.228), Python 3.6.4 amd64.

roland feec0a6909 tools/pydfu.py: Use getfullargspec instead of getargspec for newer pyusb
pyusb v1.0.2 warns about `getargspec` as being deprecated.

Damien George 92667dc2e5 tools/pydfu.py: Add support for multiple memory segments.
Segments are separated by / and begin with the memory address.  This
follows how the ST DFU tool works.

Damien George 8fb95d6520 tools/pydfu.py: Increase download packet size to full 2048 bytes.
The ST DFU bootloader supports a transfer size up to 2048 bytes, so send
that much data on each download (to device) packet.  This almost halves
total download time.

Damien George bb516af1eb tools/pydfu.py: Call set_configuration() on fresh USB device object.
This call is required before using the device (some operating systems don't
need it but others do).  Fixes issue #3476.

Dave Hylands c91727b75a tools: Fix pydfu.py to work with old and new versions of PyUSB
Update pydfu.py to match with the version from openmv.

I just updated the openmv version to work with both of the
PyUSB 1.0.0.b1 and 1.0.0.b2
