Board

ESP-C3-32S-Kit

Device Description

Datasheet: https://docs.ai-thinker.com/_media/esp32/docs/esp-c3-32s-kit-v1.0_specification.pdf
In Arduino IDE, I have selected "LOLIN C3 Pico" with "USB CDC On Boot: Disabled".
This board works correctly in other examples under these settings.

Hardware Configuration

plain module on breadboard, nothing attached

Version

latest master (checkout manually)
revision 0ef2986

IDE Name

Arduino IDE 2.3.2

Operating System

Windows 10

Flash frequency

80MHz

PSRAM enabled

no

Upload speed

921600

Description

When LittleFS.format() is invoked, the console logs the following error:

E (618) task_wdt: delete_entry(233): task not found
[   404][E][esp32-hal-misc.c:159] disableCore0WDT(): Failed to remove Core 0 IDLE task from WDT

Several seconds later, the board resets due to task watchdog.

Sketch

#include <LittleFS.h>

void setup() {
  Serial.begin(115200);
  Serial.printf("init\n");

  bool ok = LittleFS.begin();
  Serial.printf("begin %d\n", static_cast<int>(ok));

  ok = LittleFS.format();
  Serial.printf("format %d\n", static_cast<int>(ok));

  LittleFS.end();
  Serial.printf("end\n");
}

void loop() {
}

I also tried on an ESP32 chip (FQBN espressif:esp32:heltec_wifi_kit_32:UploadSpeed=921600,CPUFreq=240,PartitionScheme=default,DebugLevel=debug,EraseFlash=none).
It also emits a similar error (many times), but does not cause watchdog reset later:

You probably need to put a delay in loop() or else delete it withvTaskDelete(NULL);.

yoursunny · 2024-06-21T10:49:10Z

Adding void loop() { delay(1); } does not change a thing.
The warning on ESP32-C3 comes from disableCore0WDT called by LittleFS.format() function:

arduino-esp32/libraries/LittleFS/src/LittleFS.cpp

Lines 106 to 109 in 0ef2986

    
           bool LittleFSFS::format() { 
        
             disableCore0WDT(); 
        
             esp_err_t err = esp_littlefs_format(partitionLabel_); 
        
             enableCore0WDT();

Jason2866 · 2024-06-21T13:21:41Z

Beside the fact the function call format should do the job, format is not needed when using LittleFS. It should be possible to use the FS with

#include <LittleFS.h>

void setup() {
  Serial.begin(115200);
  Serial.printf("init\n");

  bool ok = LittleFS.begin();
  Serial.printf("begin %d\n", static_cast<int>(ok));

  LittleFS.end();
  Serial.printf("end\n");
}

void loop() {
}

yoursunny · 2024-06-21T14:04:22Z

I'm aware of LittleFS.begin(true).
My actual program is a unit test suite of my own library.
At the start of the scenario, I need to have a blank filesystem.
Hence, I want to invoke format() to ensure there's no file stored.

This was working fine with FFat but I'm trying to move to LittleFS.

Jason2866 · 2024-06-21T14:12:58Z

@yoursunny LittleFS is the smallest of your migration challenges. NimBLE Arduino will not work for the new MCUs (C6 H2). See #9836

yoursunny · 2024-06-21T14:30:23Z

NimBLE is unrelated to this.
I can use both NimBLE and Bluedroid.

dirkvranckaert · 2024-11-18T14:32:09Z

Any update on this? Running into the exact same issue. I want to be able to remove all local stored files for a factory reset, though failing on ESP32 now...

Parsaabasi · 2025-01-15T14:40:31Z

Hello,

Due to the overwhelming volume of issues currently being addressed, we have decided to close the previously received tickets. If you still require assistance or if the issue persists, please don't hesitate to reopen the ticket.

Thanks.

dirkvranckaert · 2025-01-16T06:11:28Z

@Parsaabasi The issue is still persistent for me, I'm on latest 3.1.1 ESP32 Board version on an ESP32-C6.

Whenever I do a format LittleFS.format(); or the first time deploying to a board and executing LittleFS.begin(true) (which internally if I understood correctly) is also doing a format if needed, and because it's my first deploy after getting the board out of the box (or after I deployed to it with erase flash) it's probably needed...

But what happens is that the format (or begin) seem to have worked, although couple of seconds later I run into the below exception.

I've created a simple test sketch to reproduce it:

#include <LittleFS.h>

void setup() {
  Serial.begin(115200);
  delay(5000);


  if (!LittleFS.begin(true)) {
    Serial.println("LittleFS Mount Failed");
  } else {
    Serial.println("LittleFS initiated");
  }

  LittleFS.format();

  Serial.println("Storage prepping done");

}

void loop() {
  Serial.print("Working...");
  delay(2000);
}

And the output from that test (incl. crash):

Any idea when this can be looked into? Pretty crucial failure in there for a long time...

enotanet · 2025-01-18T22:59:21Z

It seems dead library. To respond for a year...

I have the same issue on ESP32-C6 on boards 3.1.1.

Current implementation of format() is following:

bool LittleFSFS::format() {
  disableCore0WDT();
  esp_err_t err = esp_littlefs_format(partitionLabel_);
  enableCore0WDT();
  if (err) {
    log_e("Formatting LittleFS failed! Error: %d", err);
    return false;
  }
  return true;
}

(https://github.com/espressif/arduino-esp32/blob/496b8411773243e1ad88a68652d6982ba2366d6b/libraries/LittleFS/src/LittleFS.cpp#L97C1-L106C2)

Calling disableCore0WDT() is generating this error log:

E (358) task_wdt: delete_entry(236): task not found

Then enableCore0WDT() is called in format().
After 5 s there is WDT reset.

I guess that this WDT is not enabled/used on C6 board at all and enabling it is causing unexpected behavior which ends up in reset.

Simple commenting out those two lines solves the issue on C6. However I guess they were add for a reason and some condition or board specific implementation should be added.

I am experiencing the same issue described here.

dirkvranckaert · 2025-01-23T19:12:00Z

Great, I see there is progress in fixing this... @lbernstone @me-no-dev by when can we expect this to be merged and have an update available?

lbernstone · 2025-01-23T19:29:40Z

Fixes get merged in the next release. The code is there if you need it now. Remarking out the enable in LittleFS.cpp is really all you need for a quick fix.

dirkvranckaert · 2025-01-27T05:29:00Z

Applied the change on my local copy and it seems to do the job perfectly! Any idea when a next version will be released / shipped?
