Board: sipeed-maixduino, framework=arduino

Platformio Build works fine.
But I'm getting this error when trying to Upload to a Maxiduino board.

File "/Users/username/.platformio/packages/tool-kflash-kendryte210/kflash.py", line 13, in
import argparse
File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/argparse.py", line 87, in
import re as _re
File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/re.py", line 143, in
class RegexFlag(enum.IntFlag):
AttributeError: module 'enum' has no attribute 'IntFlag'
*** [upload] Error 1

This enum error only seems to affect when uploading to Sipeed/Kendryte boards.

PIO uploading to ESP8266 and ESP32 boards work fine. Only when uploading to Kendryte platform do I get this error.

Hi, @fivefishstudios

In order to make kflash run in python2, the enum module is placed in the kflash directory, which will be encountered in recent python3. You can open the kflash directory like this
C:\Users\{your user name}\.platformio\packages\tool-kflash-kendryte210
then delete the enum folder and test it again and it should be able to download successfully.

Thank you so much! It's working now.

I'm having a similar issue here

autechre:arduino-blink z$ pio run
Processing sipeed-maix-bit (platform: kendryte210; framework: arduino; board: sipeed-maix-bit)
----------------------------------------------------------------------------------------------------------------------------------------------------------------------
Error in sitecustomize; set PYTHONVERBOSE for traceback:
AttributeError: module 'enum' has no attribute 'IntFlag'

    class RegexFlag(enum.IntFlag):
AttributeError: module 'enum' has no attribute 'IntFlag'

And I didn't find this enum file to move or rename. any ideas?

edit: now I can build everything after removing enum34 using command

sudo -H pip uninstall enum34

Hi @dimitre ! This issue should have been fixed already. Could you please upload to https://hastebin.com/ the contents of /Users/z/.platformio/packages/tool-scons/tool-kflash-kendryte210/kflash.py file?
Thanks!

@dimitre Sorry, that's my bad, I gave you a wrong path. Here is the correct one /Users/z/.platformio/packages/tool-kflash-kendryte210/kflash.py

here

I removed all kflash installed through pip and pip3 and platformio installed it automagically after removing enum34
