Trying to get firmware upload example running ...
Hi. Here's where my testing stands. I have a 6022BL, not BE, but for the purposes of this code the only relevant difference should be the USB PID. I've switched the PID over to match the BE so the code here successfully opens the device. When I try example_linux_flashfirmware.py, I get:
Traceback (most recent call last):
File "examples/example_linux_flashfirmware.py", line 8, in
I am not convinced that I have the included firmware (either stock or custom) set up properly, however.
Any suggestions? Thanks very much.

If I had to guess just looking at that traceback, we're attempt to encode something that isn't a string (but is rather just a char * like payload).
Is this on Python 2 or Python 3? That encode method call really shouldn't be there (or anywhere in that codebase), as nothing that gets passed around in the library should ever be a "textual" string. I think if you remove encode, and make sure that if this is Python 3 that the data packets are bytearray or bytes types (instead of str), this will work.

I haven't made any changes to the formats of the firmware files as provided. My initial tests were with python 2.7.6. I have 3.4.3 also, but I have to figure out how to install libusb for that as a start -- pip doesn't seem to be working correctly. Thanks.
OK, I got to the point with python3 where I could run the firmware upload -- in its default configuration -- and received no error messages (or confirmation messages -- it simply exits). No red or green lights lit on the Hantek. Due to problems installing pylab for python3 (dependency errors, see below), I ended up running scopevis.py using python2 (after running the firmware upload using python3, that is). Errors from pylab install attempt below. Next post is results from scopevis.py.
