Hybrid compile won't boot -> Cache disabled but cached memory region accessed (ESP32-WROOM-32UE-N16)

[qniens]

PROBLEM DESCRIPTION

After compiling and and uploading the ESP32 won't boot and is in a crash loop.
Crash output:

ELF file SHA256: a26cc51a3

SCREENSHOTS

ADDITIONAL CONTEXT

ESP32 is an ESP32-WROOM-32UE-N16 (No PSRAM with ethernet)

(Please, remember to close the issue when the problem has been addressed)

[Jason2866]

Please test branch develop with:

platform = https://github.com/pioarduino/platform-espressif32.git#develop

Please test branch develop with:

platform = https://github.com/pioarduino/platform-espressif32.git#develop

I have deleted the content of the .platformio folder and tried it with the develop branch. It gives the the same error:

[TD-er]

Can you comment the log_d lines and maybe use very basic Serial.write calls?
Just to check if it is due to some printf (or other variant) call.

[TD-er]

Found this issue: espressif/arduino-esp32#11952

Can you call delay(1); in the loop?

[Jason2866]

Can reproduce. Need to investigate what is causing the problem. As workaround this setup can be used. Works with esp32 boards without PSRAM too.

@TD-er Changing the code doesn’t help, which is what I expected since the boot process never even starts.

Code tested:

#include <Arduino.h>

void setup() {
    vTaskDelay(2000);
    //log_d("Start");
    Serial.begin(115200);
    while (!Serial) {
        vTaskDelay(10); // Wait for serial connection
    }
    Serial.println("Start");

}

uint32_t count = 0;
void loop() {
    //log_d("Hello, World! Count: %u", count);
    Serial.print("Hello, World! Count: ");
    Serial.println(count);
    count++;
    vTaskDelay(1000);
    if (count == 20) {
        //log_d("Restarting now..."); // To see initialization logs again
        Serial.println("Restarting now...");
        ESP.restart();
    }
    delay(1);
}

[Jason2866]

The issue is caused from the bootloader. The used bootloader is build with PSRAM support / config. Even when no PSRAM finally is there, it causes issues when the bootloader tries to start a firmware which is compiled without PSRAM support.

EDIT: Wrong conclusion. Bootloader is fine. Cached compile artifacts causing the issue

[Jason2866]

fixed with ##344

To use branch develop needs to be used as platform

platform = https://github.com/pioarduino/platform-espressif32.git#develop

[qniens]

Hi @Jason2866 , thanks I will test the dev branch now. I was still running tests to pinpoint which setting in the freenove_esp32_wrover made the difference

[Jason2866]

@qniens No setting in boards manifest nor in platformio.ini is the reason for this.

Btw. this does nothing if a boards manifest is used without PSRAM (as you do). It is just littering

build_unflags =
  -DBOARD_HAS_PSRAM

[qniens]

Unfortunately it won't compile with the dev branch due to a different compile error:
