Pip install esptool выдает ошибку

Hi all —

Since migrating to V4 of the IDF (under Windows), I’ve run into an issue using esptool.py. Whereas I used to be able to run a command like this:

C:esp32_projectswifibutton>esptool.py write_flash 0x9000 nvs_reuse.bin

I now have to do it like this:

C:esp32_projectswifibutton>python C:esp32_toolchainpython_envidf4.0_py3.7_envLibsite-packagesesptool.py write_flash 0x9000 nvs_reuse.bin

Obviously not convenient. If I attempt to run it the old way, it’s as though the arguments aren’t getting passed through to the script. Did I miss a step in the installation, or is there some workaround I’m not aware of?

Thanks…

Hi mzimmers,

Are you using the IDF Command Prompt, or MSYS2, or something else?

The V4.0 Windows installer setups a Python virtualenv with a dedicated copy of Python and its own set of installed Python modules. If you run the IDF Command Prompt then you’ll be inside this Python environment.

The fact that there is a file «idf4.0_py3.7_envLibsite-packagesesptool.py» suggests that «pip install esptool» has been run while inside the virtualenv. This is not required by ESP-IDF but it’s fine, doesn’t harm anything (ESP-IDF will use the copy of esptool inside IDF_PATH/components/esptool_py/esptool).

If you’re using IDF Command Prompt, then because esptool was installed with pip in the virtualenv then you should be able to run «esptool.py write_flash 0x9000 nvs_reuse.bin» without needing anything else. If it doesn’t work in the virtualenv, try running «pip install esptool» again.

If you’re using a different command prompt, the solution may be different. Running «esptool.py» with the default Python environment (ie a normal Command Prompt) may work depending on how the Windows python installation is configured.

Hi Angus — yes, I am running the ESP-IDF Command Prompt. (I was using MYSYS2 when working with V3 of the IDF).

I’ll try re-installing esptool again tomorrow and report back.

Thanks…

No luck.

When I start up the ESP-IDF Command Prompt, here’s what I get:

Python requirements from C:esp-idfrequirements.txt are satisfied.

Done! You can now compile ESP-IDF projects.
Go to the project directory and run:

  idf.py build


C:esp-idf>

And when I try to run esptool.py, here’s the (start of) output:

C:esp32_projectswifibuttonmfg>esptool.py write_flash 0x9000 nvs_reuse.bin
esptool.py v2.8
usage: esptool [-h] [--chip {auto,esp8266,esp32}] [--port PORT] [--baud BAUD]

               [--after {hard_reset,soft_reset,no_reset}] [--no-stub]

The output is the same whether I execute the command with no parameters, or with nonsense parameters.

@mzimmers
Can you test this ?
Put the full address of the Bin file you’re flashing .. not the IDF environment
I recently has a similar issue and it was esptool needing the full path of the Bin file

@ESP_Angus
With all due respect , I found the IDF Command in windows is very inconvenient
I wish there is a way to add those to the Path and be able to run idf.py from any directory .
I use vscode and can’t find a way to invoke idf.py from vscode , because I have to use the IDF command
If I copy the link of the shortcut , I get «This has to be run from ….»
a message telling that I have to be in the directory to use the idf.py

Hi mzimmers,

Sorry, I gave you some incorrect information — I thought that «pip install esptool» would install an esptool.py.exe on the PATH, but it’s actually «esptool.exe».

I ran through the install steps on a clean VM again. You should be able to run:

esptool write_flash 0x9000 nvs_reuse.bin

In the ESP-IDF Tools Command Prompt window, and this should work.

(You could also choose to «pip install esptool» inside your global Python install to run esptool.exe from any command prompt window.)

BTW, even though ESP-IDF build system will print full paths to everything:

C:Usersgus.espressifpython_envidf4.0_py2.7_envScriptspython.exe ......componentsesptool_pyesptoolesptool.py -p (PORT) -b 460800 --before default_reset --after hard_reset write_flash --flash_mode dio --flash_size detect --flash_freq 40m 0x1000 buildbootloaderbootloader.bin 0x8000 buildpartition_tablepartition-table.bin 0x10000 buildhello-world.bin

You can strip off the first part and run this, if you’re in the ESP-IDF Command Prompt then python.exe is on the PATH:

python.exe ......componentsesptool_pyesptoolesptool.py -p (PORT) -b 460800 --before default_reset --after hard_reset write_flash --flash_mode dio --flash_size detect --flash_freq 40m 0x1000 buildbootloaderbootloader.bin 0x8000 buildpartition_tablepartition-table.bin 0x10000 buildhello-world.bin

OR

python.exe %IDF_PATH%componentsesptool_pyesptoolesptool.py -p (PORT) -b 460800 --before default_reset --after hard_reset write_flash --flash_mode dio --flash_size detect --flash_freq 40m 0x1000 buildbootloaderbootloader.bin 0x8000 buildpartition_tablepartition-table.bin 0x10000 buildhello-world.bin

(These last two work without the «pip install esptool» step required.)

Hi, Angus — thanks, that did help. Now: can anything be done about making this command briefer?

$ python C:esp-idfcomponentsnvs_flashnvs_partition_generatornvs_partition_gen.py generate nvs_reuse.csv nvs_reuse.bin <size>

Code: Select all

$ python C:esp-idfcomponentsnvs_flashnvs_partition_generatornvs_partition_gen.py generate nvs_reuse.csv nvs_reuse.bin <size>

Maybe, but it’s not straghtforward on Windows. On other OSes it’s pretty simple to add C:esp-idfcomponentsnvs_flashnvs_partition_generator to your PATH and then you can run nvs_partition_gen.py as a script…

On Windows this depends on what associations are crerated for .py files to launch with on Windows. If you can set them to launch with a Python interpreter that has all of the libraries required (either the python.exe inside the IDF virtualenv, or your global Python if you’ve installed anything that’s needed there) then this will work. But it’s outside the scope of ESP-IDF, sorry.

I’d suggest adding a custom target to your project CMakeLists file to run the generator automatically on each build, instead.

Hi
Unfortunately I have fallen at the first hurdle !
I am using a windows 10 machine, and have installed Python 2.7 and am greeted with a window detailing version number,
at the prompt I type «pip install esptool» and I receive «File «<STdin>»,line1 syntax error: invalid syntax

I have watched a few tutorials and tried different versions of python and different lines including «pip2» and «sudo» but cannot see what I am doing wrong. Python seems to be ok as no errors if I type something like «2*8» I get 16, I must be missing something silly but dont no what.
Please help.
Andy

Hi
I am so close I can taste it !!
I have finally after a few hours, and a lot of learning, got to the point where I have «erased» my lolin d1 mini and copied a «.bin» file to it both procedures completed with no errors. I have a better understanding of «esptool» now. I had to change the port from,» port /dev/ttyUSB0″ to com8 and I set the baud rate to 115200 and watched as the files where copied. I now open «PuTTY» and select com8 and yeah! the Repl appears, but (sad bit) when I type print «hello world» I get:-

>>> Print «hello world»
Traceback (most recent call last):
File «<stdin>», line 1
Syntax Error: invalid syntax
>>>

however if I type print («hello world») I get :-
>>>
>>> print («hello world»)
hello world
>>>
also if I type 2*8 I get
>>> 2*8
16
>>>
also typing help() gives me the correct page. As I said so close, and all I want to do is learn Micropython!…I will show you what happens if I hit reset on my esp8266, actualy its just «hung up» will now have to restart PuTTY. also if I do a «soft reboot» I get;-
PYB: soft reboot
OSError: [Errno 2] ENOENT
MicroPython v1.10-8-g8b7039d7d on 2019-01-26; ESP module with ESP8266
Type «help()» for more information.
>>>
Here’s another error message:-
>>>
>>> import machine
>>> from machine import pin
Traceback (most recent call last):
File «<stdin>», line 1, in <module>
ImportError: cannot import name pin
>>>
Have you any thoughts or can you point me on to the next step, sorry if the format is wrong and I am not much use from the «command line» but trying my best
Andy

Congratulations, you arrived. Now you have to learn the specifics of this Python variant.
First of all, it is more or less python 3.4. with some python 3.5 extensions. So you have to write:
print(«Hello World»)

Second: The error message:

OSError: [Errno 2] ENOENT
MicroPython v1.10-8-g8b7039d7d on 2019-01-26; ESP module with ESP8266

When booting, Micropython tries to execute boot.py and main.py in that order. On an fresh installed device, main.py does nto exist, and that causes the error message.
To get rid of the error message, you can create main.py skeleton with:

f = open("main.py", "w")
f.write("# Put your code heren")
f.close()

Third: Python is case sensitive, and the module you look for is called Pin. So use.;
from machine import Pin

Hi
Thanks !! that cleared that up and all does indeed appear to be fine, now I’m gonna have to hit the books! I now need to get into a Python mind set. I have one last request, I’ve just had a quick play and attempted to switch an Led on and off and I thought I had it correct but nothing on my Lolin/Wemos D1 Mini changed state and also Repl didn’t moan at me so I dont even no if my board is ok or my thinking is wrong, are you familiar with this board? would you show me how to toggle an LED ? does it need to be inside «main.py»? Once again thank you, your a star!

Andy

You can toggle a led on the REPL.
Use a while loop with time.sleep() for maybe half a second or so. I haven‘t got the specific code in mind but if you really fail just say so and I look it up and test it for you!

Thomas

thanks, but all is well just getting used to It, the problem I had was a dodgy breadboard so my journey has begun thanks to all!

Andy

Hi
«pip» did not work because I used a version of Python that did not contain the correct files. I then installed the latest Python and my troubles went away. If you install the latest Python follow the instructions carefully because you will be asked to check (Tick) a box that sets the proper «path» for the install, you MUST check this box! After that I found the «pip» command worked as described in the various tutorials. The other error messages that I had were fixed by following the instructions above this post which basically put something in the Micropython file «Main.py»
Hope this helps and you can move on

Andy
