Error on connecting Pyboard, no file display

[rkompass]

Hello @vshymanskyy,

thanks for suggesting to try out WebSocket/WebREPL. I'll try it tonight or tomorrow.

When connecting Pyboard (through dev/ttyACM0 here) there were a few errors like:

Error: Cannot read properties of undefined (reading 'split')
Error reading board info

Error: Cannot exec command: Traceback (most recent call last): File "", line 11, in File "", line 10, in walk File "", line 3, in walk OSError: [Errno 22] EINVAL
Execution failed .

And consequently the file manager on the left side does not show any files.

Did you try ViperIDE with a pyboard?

I tend to assume this is a problem of the pyboard MP implementation (I used the latest preview, and 1.17 (old version still there before)), as also e.g. mpflash list which is supposed to report the board fails with: Error: Failed to get mcu_info for /dev/ttyACM2 ?

I'll report at mpflash site too.

Again, no need to hurry, btw., good work takes it's time.

No, unfortunately I have lost all my pyboards ~2 years ago, so unable to test with them. I will definitely try to find a way to make the original pyboards working :)

I can send you one, if you like. Just need your postal address. :-) Also they are available on E-Bay (chinese clones, but had not problems with them, apart from low-quality female pin connectors on them).

@rkompass please try again, I've done some major changes to the core functions Remember to refresh the page to get the latest version...

The improvement I see is: No more a Micropython banner at every run. Which is good.

Do I recall correctly that you use mpremote under the hood? I noticed an issue there and reported it.

Yet no FS display.

[vshymanskyy]

No, it doesn't use mpremote under the hood :)

I tried the webrepl from micropython-lib as well as your web_repl (this repo, nicer) and both serve a html screen as expected. Yours asks for the password too. At connecting however it says Cannot connect at at the MP promt. At the promt of the w600 there is this error message (with both variants of web_repl/webrepl) :

WebREPL connection from: ('192.168.178.46', 36136)
dupterm: EOF received, deactivating

This is an older problem, but I don't know how to solve it.

[vshymanskyy]

Oh! You were using the W600!!! I just verified it with this chip, everything seems to when connected via USB. WebREPL (via the viper-tools package) fails with the same symptoms as yours. This is a W600-specific bug, as it works on ESP32 and Pi Pico W.

[vshymanskyy]

How about the Pyboard?

This is a W600-specific bug, as it works on ESP32 and Pi Pico W..

Good to know. I will report it to Robert. Perhaps he/we can find a solution.

[vshymanskyy]

I have debugged it using MPY v1.23.0 (2024-06-02) with this board: https://micropython.org/download/ADAFRUIT_F405_EXPRESS/ This should be very similar to Pyboard v1.0 and v1.1 (it uses the same MCU).

• The file tree - fixed
• File open/save - works
• Run script - works
• Package installation - fixed

Could you please re-check it with ViperIDE v0.3.1?

[rkompass]

I tested with a Blackpill board and it worked. My pyboard fails, unfortunately, still. (No file display). But note, that there was an error anyway (probably a frimware problem). I will try later with a different firmware.

[vshymanskyy]

Looks like some of your files on the board have invalid unicode in their names. Try erasing your fs

[vshymanskyy]

@rkompass did it help?

[rkompass]

It helps. After a factory reset of the filesystem viper ide is able to display the files. It also runs them. So everything seems fine.

Now the w600 has a working webrepl again (regression solved). Btw. Files structure are displayed but not file contents....

[vshymanskyy]

Works on my end. Is it pyboard or w600, or both? What exactly happens?

[rkompass]

Pyboard works, as you already announced.

The Winner w600 has now a working webrepl again, and it works partly with viper ide when connecting with your web_repl.. File structure is displayed but not file contents.... Some remaining flaw/inconsisteny of the w600 I suppose.

[vshymanskyy]

I see, so this only affects webrepl on w600. I can check it on my end. Do i need to rebuild the w600 firmware?

[rkompass]

No. You can take that from robert-hhs shared stuff.

This issue may be closed now.
