Compatibility issue with esp32doit-devkit-v1

[DrA1ex]

Hello there!

I encountered an issue while using the project with the esp32doit-devkit-v1 board. It's stuck in a boot loop with the LED blinking. When I checked the Serial, an error message appeared:

Guru Meditation Error: Core 1 panic'ed (LoadProhibited). The exception was unhandled.

Unfortunately, it didn't provide any stack trace or other details, only register values.

After investigating, I tried the platform version "espressif32@4.4" (the latest 4.x version available). This resolved the problem, and the project now board detects by PulseView. However, I'm uncertain about any potential impact or consequences of this change, so I didn't create a Pull Request.

I also experimented with the latest version (6.4.0), but it didn't work at all. I only received random serial output, and PulseView didn't detect the board.

I'd like to request the project owner to investigate this issue and consider changing the version to "espressif32@4.4" if it's appropriate.

Thank you for looking into this. I hope this information is helpful.

However, the board is only detected by PulseView, but it doesn't capture anything. Therefore, there may be more incompatibilities

You pointed me on the right track, I got it working locally by using 4.1. 4.0 failed with the error you got and later ones didn't capture but 4.1 was the sweet spot.

[env:esp32doit-devkit-v1]
platform = espressif32@4.1
board = esp32doit-devkit-v1
framework = arduino
build_flags = -DCORE_DEBUG_LEVEL=0
monitor_speed = 921600

Hi @DrA1ex ,

I forked this project and resolved the bootloop issue. You can try it here:

@magico13 Did you change anything else? Do you remember the settings you used in PulseView?

Using the current Version (https://github.com/EUA/ESP32_LogicAnalyzer/tree/5d7efc1369e1af6f622f830ad6c238b0338cbc2d) - which is older than your comment here - and changing just what you mentioned, I can compile and upload the project in PlatformIO to a ESP32 DEVKITV1 board with a ESP32-WROOM-32 module. PulseView does recognize a "ESP32 Logic Analyzer v0.31" device. However, I seldomly get any captured data.
