how to configure PlatformIO ESP32 project for CoreDump

Postby Mark1D » Mon Oct 21, 2019 1:00 pm

Hello,
I am trying to troubleshoot some problems in an ESP32 project. I am using PlatformIO. How do I configure my project to save core dumps to flash and then how do read out those core dumps? Any assistance/pointers is greatly appreciated.

thanks,
mark

You have to enable core dump to flash in menuconfig, edit the partitions.csv to include a coredump partition and then call espcoredump.py

It's described in this page: https://docs.espressif.com/projects/esp ... _dump.html

I've tried to follow these steps this weekends but was unable to read out the dump after the crash happend, so if you learn the tricks, please share them (:

Thanks. but what is menuconfig? that is not obviously available in PlatformIO. Sorry for being daft, but I inherited this project from someone and did not set it up from scratch.
Also, this project started as an Arduino project, so it is not a pure ESP-IDF project, if that matters.

menuconfig, is how you configure the many, many settings of the ESP32. You can kind of think of it as the BIOS for the ESP32.
have a look at this post
viewtopic.php?t=7416

One huge problem using Arduino for the ESP32 is that many of these settings are fixed, and most users are not even aware of them. PlatformIO is a great IDE, but sadly the lack of implementing a way to edit settings in menuconfig killed it for me.

Question: is it Arduino that fixes many of the config options, or is it that PlatformIO does not expose them for editing? changing IDEs is easy, but I am uncomfortable switching off of Arduino platform at this stage of development.

Can esp-idf be used seamlessly with arduino? that is, can I install the esp-idf tools and use them in conjunction with Arduino platform?

thanks for the help.

It's both. Arduino has fixed values which is in and of itself a messed up idea. I am not sure why PlatformIO does not allow it because I use VisualStudio Code, and have hotkeys to get to it.

Search the forums here. I have seen a couple times at least where we were told that using ESP-IDF you can use Arduino code style in IDF.
I have no tried it though.
