M5Stack Official ESP32 Camera Module - Demo, Runtime Error

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

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

@calin

Did you mean soder directly on ESP32 chip pinout?

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

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" :)

@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,
:)

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.

@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,

@pksuf07 Hi, This is the ESP32CAM pinout

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

Faulty device?
