Faulty device?

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,

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

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.

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" :)

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

Hi, try prebuilt firmware:
https://github.com/m5stack/esp32-cam-demo/blob/m5cam/m5cam-firmware.zip

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

@pksuf07 在 M5Stack Official ESP32 Camera Module - Demo, Runtime Error 中说：

@calin

Did you mean soder directly on ESP32 chip pinout?

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


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.

Kyu

@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...
