ESP32 Platform Framework Version 3.20004.0 leads to crash on specific Module.

Simple Test App:

#include <Arduino.h>

unsigned lcount;

void setup() {
  // put your setup code here, to run once:
  Serial.begin(115200);
}

void loop() {
  // put your main code here, to run repeatedly:
  ++lcount;
  Serial.printf("Nr: %u %s\n", lcount, ESP.getSdkVersion());
  delay(1000);
}

Running on TTGO Module labelled "T8_V1.7.1 20190702" with Chip Revision 1: ............................. Nr: 13 v4.4.1-472-gc9140caf8c Nr: 14 v4.4.1-472-gc9140caf8c ............................. works as expected.

Running on TTGO T-Display Module labelled "19-6-28 V1.1 XY-CP" with Chip Revision 3: idf_monitor.py gives the following output:

My first guess: The problem occurs on (some?) Modules with ESP32 Chip Revision 3.

By the way, the problem did not exist with Framework Version 3.20003.220626

Hi @Rai-Sp ! Does it work correctly in the Arduino IDE?

Hello valeros, I am not sure, that I got your question corretly. I have installed Ardino IDE 1.8.19, using https://dl.espressif.com/dl/package_esp32_index.json (1.0.6) The program runs on T-Display Module , but outputs "Nr: xxx v3.3.5-1-g85c43024c", meaning that a very different SDK Version is used.

You installed an outdated package from the old index file, please uninstall it completely. You need the following index file https://raw.githubusercontent.com/espressif/arduino-esp32/gh-pages/package_esp32_index.json and the version 2.0.4

Hello again, I have changed ESP32 Package (now 2.0.4). The program runs on T-Display Module and outputs: "Nr: xxxx v4.4.1-472-gc9140caf8c", meaning that the correct SDK Version is used.

Does it work with the ESP32 Chip Revision 3?

By the way, I have tested a second T-Display Module with PlatformIO to make sure it's not a hardware problem. But the problem persists, so two samples ot the T-Display Module with Chip Revision 3 have the same problem with PlatformIO.

Exactly the same piece of harware works with Arduino IDE.

Please provide here your platformio.ini file.

[env:esp-wrover-kit]
platform = espressif32
board = esp-wrover-kit
framework = arduino

monitor_speed = 115200

Please attach here also a screenshot of your board configuration in the Arduino IDE.

One more piece of information: I am using the T-Display Module in a quite complex application, built with ESP-IDF and Arduino Libraries. The Version are exactly the ones labelled "v4.4.2" and "2.04", and evrything works as expected.

Please try

[env:esp-wrover-kit]
platform = espressif32
board = esp-wrover-kit
board_build.flash_mode = qio
framework = arduino

monitor_speed = 115200

It works with board_build.flash_mode = qio. Thanks for your assistence.

Anyway, board_build.flash_mode = qio was not necessary in previous versions.

By the way, I know that TTGO T-Display Module is not kind of "esp-wrover-kit" (has no PSRAM), but I left it as I am using the original espressif Wrover-Kit quite often (for debugging).

Another strange experience: When everything was fine, "just for fun", I removed .platformio folder completely and let PlatformIO Installer do its work (took a very long time). After that, it also worked without board_build.flash_mode = qio. Before, I had just upgraded from 5.0.0 to 5.1.0; maybe something went wrong during this step?

So, I close the issue now, and many thanks again.
