Well, this will trample over any files you have installed from your package manager, and possibly cause conflicts when you upgrade your system later on. Pip does a "user" install in your home directory by default since quite a while when you run it without sudo, and that is much safer. It's not a big deal, but lets you avoid trouble in the future.

You are absolutely right. Avoiding trouble with package managers/software managers should always be top priority. So using local virtual environments or user environments usually is the safest and sufficient way to go.

The above case had a missing python module and using pip to install additional modules is usually quite safe. Even with pip having no uninstall can be solved by deleting the package directories by hand, which of course is bad behavior as well in case you are not experienced in this and know what you are doing.

"sudo pip install ..." is following our german saying "Was nicht passt wird passend gemacht!"

fwiw, my install is relatively clean in a vm with all the latest os updates and code. No extra pip installs. See my how-to script.

Perhap the Debian py serial went bad/missing. (?) I'll revert to snapshot and start over if there's no interesting troubleshooting to be done. Odd coincidence that I also have failed tests, both when testing from Debian aso well as RPi.

gojimmypi, I don't want to discourage you (so please don't be), but I'd say it's too early to provide "automation scripts", and especially offer it to other people, if you can't solve such issues. It's a typical novice problem - trying to "automate" everything, instead of taking chance to do every bit yourself gazillion of times, learning what problems may arise, and learning how to solve them. Your pyserial problem is that you installed package for python2, but that script calls python3. Your failed tests problem is likely proverbial "Debian stable" problem, where Debian ships damn old stuff like Python 3.2, whereas MicroPython requires at least 3.3. The points is: this topic is about testing MicroPython ESP8266 port, not about testing your incorrectly setup or outdated Debian or Raspberry. It would be nice to keep this topic clean and not confuse other people, whereas help on Debian/Pi can be gotten on forums specialized to them.

It shows, eh?

yes, that's true, my last embedded Microcontroller Development experience was with an Orion Unilab with the 65C02. I'm trying to wean myself off years of Microsoft-only development since then.

Actually - this was a fresh Debian Jessie with Python 3.4.2 (default, Oct 8 2014, 10:45:20) [GCC 4.9.1] But you are quite right about my novice status. Here's the fix regarding the serial not found error:

I completely overlooked that as the "esptool.py --port /dev/ttyUSB0 flash_id" worked.

Code: Select all

sudo apt-get install python3-serial

yes, sorry. I thought it was related as this latest compile that also gave some failed tests on the RPi. I believe both environments are completely up to date.
fwiw - even with the serial install, I'm still not able to get the tests to run from the Debian machine even though the MicroPython compiles properly and seems to otherwise work:

When I try to run the tests, there's no response. After 30 minutes or so when I press Ctrl-C, I see this:

It seems to get stuck on the pyb.enter_raw_repl()

If my reply here is inappropriate, well I won't be offended if my message gets deleted. I do think it is related to the testsuite. I always think that if I have a problem, others might also. If you disagree, well... sorry. my bad.
