ESP32-CAM test crashes in 2.0.2- OK in 1.0.6 #6526

fanfanlatulipe26 · 2022-04-03T15:53:07Z

Board

ESP32-CAM

Device Description

"Simple" (?) ESP32-CAM module here from Banggood

Hardware Configuration

No other connection.
Powered by FTDI on an USB port of the PC or with an external 5v power supply. (FTDI only for upload /debug)

Version

v2.0.2

IDE Name

Arduino IDE 1.8.19

Operating System

Windows 10

Flash frequency

80Mhz

PSRAM enabled

yes

Upload speed

921600

Description

When compiled with release 1.0.6 the test case run as expected.
With exactly the same hardware (same PC, same FTDD, cable ....;) but with release 2.0.2 it crashes very often, with ramdom (??) causes.

The code is exactly this one from a tutorial at randomnerdtutorials.com
Raw code is here.
Small websever (using ESPAsyncWebServer) with a web page allowing to take a picture (always under the same name), save it in SPIFFS and display it on demand.
(I am aware of the need of config.grab_mode = CAMERA_GRAB_LATEST; for this kind of application in 2.02)

The original demo turns off the brownout detection, but even with the brownout detection enabled the results are bad and there is no explicit crash for brownout detection. Does not seem to be a power supply problem. Tests were also done wih external power supply.

Same test adapted to use the SD card instead of the SPIFFS run perfectly in 2.0.2
For this adaptation I just changed the #include and the .begin

//#include <SPIFFS.h>
#include <FS.h>
#include "SD_MMC.h"            // SD Card ESP32 + fs ++++++++++++++++++++++++++++++
#define SPIFFS SD_MMC         // SD Card ESP32 + fs +++++++ and change the .begin(  )

and 

// if (!SPIFFS.begin(true)) {
  if (!SPIFFS.begin("/sdcard",true)) {    //  +++++ changed for SD . Prevent use of pin 4 the LED

ESPAsyncWebServer version 1.2.3
Code compiled for AI Thinker ESP32-CAM board or ESP32 Dev Kit with psram enabled. Same results.

Other Steps to Reproduce

Test OK with 1.0.6
Test OK in 2.0.2 if SD card is used instead of SPIFFS
In fact I see other crashes than the ones reported here, but could not reproduce at capture time :-<
Crashes not the same with debug level none. (see the 2 logs , separted with ++++++++++++++++++)

I have checked existing issues, online documentation and the Troubleshooting Guide

I confirm I have checked existing issues, online documentation and Troubleshooting guide.

Hello. is the error the same for 2.0.3-RC1?

Jason2866 · 2022-04-04T11:03:11Z

The test sketch is not working.

src/main.cpp: In function 'void loop()':

fanfanlatulipe26 · 2022-04-04T11:10:23Z

Don't know how to install 2.0.3-RC1
May I have both version 2.0.2 and 2.0.3-RC1 at the same time and an easy way to switch from one to the other ?

me-no-dev · 2022-04-04T11:14:46Z

decoding those exceptions can also help much. (And it is a requirement) https://github.com/me-no-dev/EspExceptionDecoder

fanfanlatulipe26 · 2022-04-04T11:20:10Z

Well: there is no stack in the output, just "Backtrace:0x400ea765:0x3ffbee0c |<-CORRUPTED"

fanfanlatulipe26 · 2022-04-04T11:24:16Z

@Jason2866 : no problem in Arduino IDE.
Maybe just need to add the function prototype before

Jason2866 · 2022-04-04T12:20:05Z

In general there is no problem with the webcam. We have a webcam build with Tasmota and it worked never so stable as with core 2.0.x

fanfanlatulipe26 · 2022-04-04T12:34:16Z

Test done with 2.0.3-RC1:

small testcase with no wifi / webserver runs perfectly.
test case with the webserver runs also pretty well, but many messages in the log, such as
cam_hal: EV-EOF-OVF
or
cam_hal: EV-VSYNC-OVF
Doesn't occur in 1.0.6
The program needs to take 2 or more picture in order to get one really stored in the SPIFFS. Don't understand.

Doesn't occure if the picture is save on the SD card instead of the SPIFFS

Here is a log (no more information if compiled with debug level "debug")

I just see you mentioned ESPAsyncWebServer problems, it can be probably related to this issue? #6502?

fanfanlatulipe26 · 2022-04-07T17:09:37Z

The mix SPIFFS + ESPAsyncWebServer have a strange behavior.
