M5Stack Official ESP32 Camera Module - Demo, Runtime Error

[pksuf07]

First of all, if I violate any community posting rule, please forgive me because it is my first time.

I bought two ESP32CAM units (https://www.aliexpress.com/item/M5Stack-Official-ESP32-Camera-Module-Development-Board-OV2640-Camera-Type-C-Grove-Port-3D-Wifi-Antenna/32881414545.html?spm=a2g0s.9042311.0.0.3da24c4dBymjBW) and tested with esp32-cam-demo (https://github.com/igrr/esp32-cam-demo).

One unit was OK but I have problems with the other unit:

First of all, flashing was not easy. I made success 1 out of 4~5 tries after I hold down and release reset button (download mode).

Secondly, the camera was not probed properly. So, I installed the camera again and it probed (detected) ov2640 camera ok. Now, it reboots while it initiating wifi as follows.

Rebooting...

Does any one have resolved this issue?

I requested how I can replace this unit through Aliexpress but haven't got any reply back.

I am hoping I can fix the issue because it's going to take long time to replace the possibly defective unit.

Any solution ? Or any recommendation?

Check the project idf config using make menuconfig option.
In this situations, a debugger will be very helpful.

@calin

Appreciate your reply. The problem is that for this new module I do not any other pinouts except USB Type-C and Grove to connect JTAG, SWD, or any other debugging interfaces. I have to confess that I am not expert on this issue but if you know how I can do? I enabled gdb stuff in menuconfig. But I am wondering if I can connect OpenOCD and gdb through it.

Can you enlighten me?

Thanks,
Kyu

Check the wifi config on project menuconfig.
The Jtag connect's to GPIO's 12,13,14,15,RST and GND on ESP32.
If you really whant to use a Jtag on that one, you can use any FTDI based Jtag and you must solder some wires to ESP32 Jtag pin's...

@calin


I would if the unit is like DevKit but as you can see in above picture. No pinout for soldering. Did you mean soder directly on ESP32 chip pinout?

I appreciate your attention to my question a lot.

Hi, try prebuilt firmware:

That firmware should do... if the hardware is OK

Well... yeah... if you are determined to debug...

@bin

Hi Bin,
This works. It probed camera good and got connected. Can you enlighten me there is any changes in the source code?

@calin

Thanks for advice. I feel sorry I do not have skill and equipment to solder ESP32 Chipset pint out for debugging which I would love to learn to .

@Bin
I will try.

I will try.

Here is my M5Stack debug setup: a "home made" Jtag, some ESP32 board and a ILI9341 TFT.
And M5Stack device running (almost) the same code :)

Too bad the actual M5Stack don't have a touchscreen... i can use the touchscreen on the debug "setup" :)

[pksuf07]

@calin

Appreciated your information and picture.

I am already able to configure the debugging setup. I have done it but I could not with ESP32CAM.

By the way, it seems to me that you are using platform I/O which I do not use. So, I will try as per your configuration.

And I do not have m5stack core and accessory units except ESP32CAM.

In fact I am interesting ESP32CAm only if it can handle some real time application because I believe it can off-load some of processing with ESP32, especially by pipelining processing frame while it streaming. For example stereo vision for distance. This is just hobbiest's thought.

Thanks,
:)

[Calin]

I can't debug on M5Stack Core because it use GPIO 14 as TFT CS and that's interfering with Jtag TMS line.
That's why i made this setup for debugging.

[pksuf07]

@calin
Understood. I am sorry I do not have M5Stack core. Only ESP32CAM. I now understand your setup little bit.

I should keep in touch with you more to learn from you more.

[pksuf07]

@bin

Hi bin,
Can you give little information on the changes or setup I am missing? I tried to make this as STA and giving static ip address. The firmware you uploaded is good for softAP.
Thanks,

@0x1abin The prebuilt firmware doesn't work for me either. I get this:

Faulty device?
