ESP32: esptool: error: too few arguments

This is the last part of the output with --verbose:

I already uninstalled and reinstalled PlatformIO and all related plugins from Atom.

Any idea what’s going on here?


#2

I cannot reproduce this.

Could you provide the output of pio --version and do a pio platform update (and maybe a pio upgrade --dev)?

When I build the blink example:

Please wait while upgrading PlatformIO ...
PlatformIO has been successfully upgraded to 3.5.3rc2
Release notes: http://docs.platformio.org/en/latest/history.html

And still same result.


#4

Our used esptool.py is different (esptool.py v2.1 vs esptool.py v2.3.1). Did you get the newer version after updating? Is still using the one from tool-esptoolpy@1.20100.0\esptool instead of the newest version 1.20310.0?

Also you have multiple versions of the ESP32 platform packages installed, some fixed version and a staging version? What’s your platformio.ini?


#5

This is my platform.ini:

It used to work fine, until one of the last updates last week. (not sure if it is one of the last updates, I installed it last week)


#6

That file uses a fixed-version platform = espressif32@0.12.0 at line 63. Comment that line out and uncomment line 64. Does that work now?

Otherwise try if you can reproduce this with a simple blink example, that platformio.ini file has 594 lines. The fixed version is probably the problem. combined that is uses a different esptool.py version, suddenly.


#7

Still the same when using the staged version.

I will try to locate the Blink test version.


#8

It was linked above (https://github.com/platformio/platform-espressif32/tree/master/examples/arduino-blink). Does it upload normally with an unmodified platformio.ini? What if you put platform = espressif32@0.12.0? (BTW, when multiple enviroments are defined, you can use pio run -t upload -e esp32dev to use a specific environment)


#9

I built the blink example.

#10

For me the blink example compiles and uploads fine with both

platform = espressif32

and

platform = espressif32@0.12.0

With the @0.12.0 it outputs

Where it correctly uses framework-arduinoespressif32@1.4.0\tools\esptool.py (yours shows framework-arduinoespressif32\tools\esptool.py)

Weird. I suggest purging your entire PIO installation and starting from scratch. At first make sure you uninstall everything ESP32 related (pio platform uninstall espressif32). Uninstall the plugin, search for your .platformio folder, delete everything in it, and re-install the plugin.


#11

Would it be a good idea to also install everything in another folder?

And what is all PlatformIO related?
Is it also somewhere configured in Atom or VScode in another location other than the path of my Github location?


#12

It should be good enough if every PIO was purged completly. If you installed it from CLI I’d to pip uninstall platformio (as admin), then delete the entire C:\Users\gijs\.platformio folder. If your IDE has a built-in core, you need to uninstall the plugin and search for the .platformio folder with the Windows Explorer. (http://docs.platformio.org/en/latest/faq.html#multiple-pio-cores-in-a-system)


#13

Took a while, I removed everything related to PlatformIO, but still the same issues.
I guess I will go to sleep now and try to think about what to do next.
I’ve already been trying to get this to work for 4 evenings now.
I’m close to the point of format C: and reinstall everything on my laptop, which will probably take another 4 days to get it all working again.

Maybe I will try to get some other PC to install this and see if that will work with the latest PlatformIO.


#14

See https://github.com/platformio/platform-espressif32/issues/89

We will release PIO Core 3.5.3 ASAP.


#15

I just feel so stupid. Tried to upgrade to 3.5.3, but it keeps reporting

You’re up-to-date!
PlatformIO 3.5.4a1 is currently the newest version available.

And (ofcourse?) it still does report:

All updated, same result.

  1. Please remove ~/.platformio/platforms folder
  2. Also, try to remove arduinoespressif32 package from ~/.platformio/packages folder. It seems that you have different framework source code and dev/platform.
