ESP32 - python.exe doesn't support asyncio --no-hints

[BenR]

Hello,

For anyone experiencing this.

python.exe doesn't support asyncio. The issue can be worked around by re-running idf.py with the "--no-hints" argument.

This seems to be cropping up a lot at the moment. Until we work out a catch all fix anyone with this problem will need to do the following.

First make sure you are fully up to date with libray updates by clicking Help -> Library Updates, changing Files in use to Full Database and getting the latest files. Next check if you can compile, it could be we have already solved this issue with an update.

If you're still getting the error then continue.

Navigate to this directory by copying and pasting the path into your file explorer address bar.

V9

Code: Select all

C:\ProgramData\MatrixTSL\FlowcodeV9\FCD\ESP\Batch

V10

Code: Select all

C:\ProgramData\MatrixTSL\FlowcodeV10\FCD\ESP\Batch

Open the file esp32_build.bat in a text editor by right clicking the file and selecting edit.

Find these lines.

Code: Select all

@idf.py build
REM @idf.py --no-hints build

Move the REM up a line so you get this instead, the REM is basically commenting out the rest of the code on the line.

Code: Select all

REM @idf.py build
@idf.py --no-hints build

Save and close the file.

Now repeat with the file esp32_prog.bat

These lines

Code: Select all

@idf.py -p %PORT% -b %BAUD% flash
REM @idf.py --no-hints -p %PORT% -b %BAUD% flash

Change to look like this.

Code: Select all

REM @idf.py -p %PORT% -b %BAUD% flash
@idf.py --no-hints -p %PORT% -b %BAUD% flash

Save and close the file.

Hopefully Flowcode can now compile correctly.

Be careful when doing library updates as this will try and overwrite the batch files back to factory defaults. If you do overwrite the files you may have to re-apply the fix.

Not sure what has changed but i'll keep investigating how we fix this for everyone without breaking existing working setups.

Some advice on creating a working ESP32 toolchain is offered here.

Thanks!

Hi,
That fixed it for me as well. It is just as well it is quite a capable and cheap device to make it worth the initial pain setting it up.

I just had this issue and doing the library updates resolved it for me. Thanks.

Hi all,

Having the same issues after installing the ESP Tool chain! I expect this kind of fixes to be done on the feature updates of FC10 without the need of release FC11 !

Thanks for the information of this topic i fixed the compilation error and now the ESP package is working.


Regards
George

Hi George.
The only fix required is a Full database library update, as the editing of the file is no longer required for FC10.
No need to wait for Flowcode v11 for a fix.,
