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,

@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.

@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

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.

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

@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.

@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

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.

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?
