ESP32 driver fails when enabling either WebUI, Telnet or Websocket in platformio.ini

[msepulve]

Hi!
As described in issue #637, I’m experience exactly the same problem but tracked it to the enabling of any of WebUI, Telnet or Websocket.
I’m compiling the fw with PlatformIO under Ubuntu 24. Fresh installation following step by step the installation process described for grblHAL. Target board is MKS TinyBee Bee that works fine with files from Web Builder.
File partitions_8mb.csv is the same used by Web Builder and sdkconfig.mkstb is just sdkconfig modified to take account of the 8 MB of flash, the partitions_8mb.csv table and 240 MHz.
Please help me to find out what brokers the working of the driver making it cycle.
my platformio.mkstb.ini is as follows:
[platformio]
src_dir = main
include_dir = main

[wifi_networking]
build_flags =

[env:mkstb]
platform = espressif32 @ ~4.0.0
framework = espidf
board = esp32dev
board_build.partitions = partitions_8mb.csv
board_build.filesystem = littlefs
board_build.embed_files =
  main/embedded/favicon.ico
  main/embedded/ap_login.html
  main/embedded/index.html.gz
build_flags =
  -Wimplicit-fallthrough=1
  -Wno-missing-field-initializers
  -Wno-maybe-uninitialized
  -Wno-stringop-truncation
  ${wifi_networking.build_flags}

Sorry, the original issue is #634 posted by Domingo

Do you have a stack trace?

Here is what is seen in the terminal terjeio,

Keeps coming endessly. It occurs when fw is compiled with either WebUI, Telnet or Websock enabled. Only WiFiClientSecure enabled doesn’t produce the problem.

[terjeio]

You will have to decode the backtrace to see where it fails, but for a watchdog failure that might be in framework code so likely not very helpful.

Earlier I had to add code to run the idle task periodically, this is hooked into the main grbl protocol loop that normally runs at a high frequency. Every 250 ms it forces the idle task to run, can you try to reduce this to e.g. 100ms and see if that helps?

[msepulve]

Thanks terjeio. Tryied values 200, 150, 100, 75 and 25 to no avail. The same problem keeps coming.
Should you have any ideas please let me know.

Let’s add that in order to be absolutely sure that the Tiny Bee was not a problem, I downloaded today firmware from the Web Builder that uploaded to the TB runs as expected with all the services operating. So the problem is definitively caused by firmware compiled by me.
