Occasional OTA crash

[poengAlex]

Hardware:

Board: ESP32-wroom-32D (custom board)
Core Installation/update date: 1.0.0?
IDE name: Arduino IDE
Flash Frequency: 80Mhz
PSRAM enabled: no
Upload Speed: 115200
Computer OS: Windows 10

Description:

Hi

I have build a simple test program to check the OTA functionality on ESP32. There are 2 versions of a bin fil I download with on integer value different in the two. Both programs start OTA and download the other bin file. If the same bin fil starts after a reset the OTA must have failed somehow. I also have a timer that restarts the MCU after 5 minutes.
After running the program over the weekend I have 6722 successful OTA and 162 fails. 2.4% fail rate. There is a few instances (<5) where the MCU simply freeze and do the restart failsafe kicks in. But the most of the failures there is a LoadStoreError. The full exception you can find bellow.
Do anyone else have this problem? Any solutions?

Sketch:

	Update.onProgress(OnProgress); 
	ESPhttpUpdate.rebootOnUpdate(false);
	t_httpUpdate_return ret = ESPhttpUpdate.update(bin);

	switch (ret) {
	case HTTP_UPDATE_FAILED:
		Serial.printf("HTTP_UPDATE_FAILD Error (%d): %s", ESPhttpUpdate.getLastError(), ESPhttpUpdate.getLastErrorString().c_str());
		vTaskDelay(1000);
		ESP.restart();
		break;

	case HTTP_UPDATE_NO_UPDATES:
		Serial.println("HTTP_UPDATE_NO_UPDATES");
		vTaskDelay(1000);
		ESP.restart();
		break;

	case HTTP_UPDATE_OK:
		Serial.println("HTTP_UPDATE_OK");
		vTaskDelay(1000);
		ESP.restart();
		break;
	}

[me-no-dev]

which version of the core are you running?

[poengAlex]

How can I check that? It looks like I have 1.0.0

But it happens to me all the time, and I code is just the example code introduccing my SSID, PASSWORD and URL where the .bin file is.

#include <Arduino.h>
#include <WiFi.h>
#include <WiFiMulti.h>
#include <HTTPClient.h>
#include <HTTPUpdate.h>
WiFiMulti WiFiMulti;

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

  Serial.println();
  Serial.println();
  Serial.println();

  for (uint8_t t = 4; t > 0; t--) {
    Serial.printf("[SETUP] WAIT %d...\n", t);
    Serial.flush();
    delay(1000);
  }

  WiFi.mode(WIFI_STA);
  WiFiMulti.addAP("MYSSID", "MYPASSWORD");
}

void loop() {
  if ((WiFiMulti.run() == WL_CONNECTED)) {

    WiFiClient client;

    t_httpUpdate_return ret = httpUpdate.update(client, "http://server.com/public_html/V1.0/sketch.bin");

    switch (ret) {
      case HTTP_UPDATE_FAILED:
        Serial.printf("HTTP_UPDATE_FAILED Error (%d): %s\n", httpUpdate.getLastError(), httpUpdate.getLastErrorString().c_str());
        break;

      case HTTP_UPDATE_NO_UPDATES:
        Serial.println("HTTP_UPDATE_NO_UPDATES");
        break;

      case HTTP_UPDATE_OK:
        Serial.println("HTTP_UPDATE_OK");
        break;
    }
  }
}

Thanks!

Looks like it always related to the WiFiClientRxBuffer::read.

[stickbreaker]

LoadStoreFailure is a Buffer location error, the referenced data location is not within the Cpu's RAM. Set Core Debug Level to ERROR or WARNING and rerun your test. See if the RAM allocation error is listed in the console log.

@stickbreaker I have tried it already. There were nothing in terminal output. I have tried those both debug levels.

[stickbreaker]

@nikuz Reading through HttpClient. it looks like it is a heap fragmentation error. Strings are used extensively.
Try adding a heapfree call before and after the update()

Serial.printf("Free internal heap Before update %u\n", ESP.getFreeHeap());

    t_httpUpdate_return ret = httpUpdate.update(client, "http://server.com/public_html/V1.0/sketch.bin");

Serial.printf("Free internal heap After update %u\n", ESP.getFreeHeap());

Chuck.

[atanisoft]

String and Stream both had a few bugs in them when exactly 64 bytes was printed, these were fixed on master a week or so ago. There may be other heap leaks in there still though.

[nikuz]

@stickbreaker same behaviour even with the heapfree call. I have added the additional log for progress monitoring. Looks like LoadStoreError always happens on the 237568 bytes of stream download. I have tried to update to two different *.bin sketches, which has a not the same size..

[nikuz]

One time I got this error with debug log ERROR enabled, right before LoadStoreError:

(34214) esp_image: invalid segment length 0xfefefefe
[E][HTTPUpdate.cpp:408] runUpdate(): Update.end failed! (Could Not Activate The Firmware)

[nikuz]

Sometimes updates happens. I'll check, maybe something wrong in my environment. Maybe I'll move the update file somewhere closer to the esp itself.

[lbernstone]

I am able to reproduce with a minimal sketch. I'll dig in and take a look.

#include <WiFi.h>
#include <HTTPClient.h>
#include <HTTPUpdate.h>

#define MYSSID "ssid"
#define MYPWD "password"
#define SKETCH_URL "http://s3.amazonaws.com/esp32-lb/wifikittest.ino.bin"

void setup() {
  Serial.begin(115200);
  WiFi.begin(MYSSID,MYPWD);
  if (WiFi.waitForConnectResult() == ESP_OK) {
    log_e("Connection Failed!");
    return;
  }

  WiFiClient client;
  t_httpUpdate_return ret = httpUpdate.update(client, SKETCH_URL);
}

void loop() {}
