Description

When encountering Core dump data check failed, it shows that ESP32-S3 has a core dump error.
Tried the following but couldn't improve it

Try lowering the resolution or JPEG quality of FRAMESIZE_UXGA to FRAMESIZE_SXGA or FRAMESIZE_XGA and setting jpeg_quality to between 12-15.

Set the framebuffer to fb_count = 1.

Reduce config.xclk_freq_hz = 20000000 to 10000000,

it's OK if you get this error. it should not prevent your sketch to run. You can erase flash to get rid of it

I tried wiping the flash to get rid of it, but the ESP still reboots.

please compile with core debug level Verbose. There is another reason why your board reboots

I have a similar issue - probably the same issue.

My update routine copies a compiled firmware file into LittleFS and then uses the Update library to upgrade the module software from this file. Update code is pretty much identical to the examples included with the library.

void updateFirmware() {
	events.send("Firmware upgrade started.", "messagecr", millis());
	File file = LittleFS.open("/firmware.bin", "r");

	if (file) {
		size_t updatesize = file.size();

		if (Update.begin(updatesize)) {
			size_t written = Update.writeStream(file);
			if (Update.end()) {
				if (Update.isFinished()) {
					events.send("Firmware update completed successfully. Click 'Reboot' to restart.", "messagecr", millis());
				}
				else {
					events.send("ERROR: Update not finished - something went wrong!", "messagecr", millis());
				}
			}
			else {
				events.send("ERROR: Error Occurred. Error #: " + Update.getError(), "messagecr", millis());
			}
		}
		else {
			events.send("ERROR: Not enough space in flash.", "messagecr", millis());
		}
	}
	else {
		events.send("ERROR: Can't open firmware file.", "messagecr", millis());
	}
	file.close();
}

The upgrade works fine. The sketch runs fine. No issues.

However I get the following on boot:

If I update over serial and use the 'erase flash' option then the issue goes away. But once i do my code update it comes back.
