Problem uploading to ESP32-CAM with ESP-Prog

Using PlatformIO in VSCode with an ESP-Prog connected to ESP32-CAM module. When I started working with this project, I could Upload to the ESP32-CAM without pulling the GPIO0 to GND, now I find I need to do that each time to upload my code.

Is there a setting I can use to get around this?

I simply cannot get flashing or debugging of ESP32-CAM working with PlatformIO in VSCode. The only way to flash is as described in my original post, i.e. hold GPIO0 low and power-cycle the ESP32-CAM. The power cycle is required because the reset button is pretty much inaccessible when the module is mounted on a breadboard. Even using this “trick” I cannot get the debugger to work at all.

Has anyone succeeded in flashing and debugging ESP32-CAM with VSCode, PlatformIO, and ESP-Prog? If you have any pointers you have would be very much appreciated. I cannot imagine doing my project with the println debugging as my only choice, that is why I chose PlatformIO.

Many thanks, I hope the community can help :slight_smile:

Does it behave the same in the Arduino IDE? Which settings do you use there?

Hi @maxgerhardt I think part of the issue is that the ESP32-CAM has an SDCard onboard, and it uses the same pins as JTAG. I am basing my project on one that uses the SDCard so I am currently removing the SDCard code since I do not need it for my application.

I will report back here when I have done that on any progress made.

Many thanks.

Things appear to be better. Here is the log when trying to start debugging. There appear to be a number of issues, but I don’t know what they mean:

Can you set debug_speed = 500 in the platformio.ini and see if it gets better?

Hi @maxgerhardt Some progress to report:

First, I could not get the Arduino to upload code to the ESP32-CAM without manually operating Reset and GPIO0. I connected GPIO0 to the DTR output of my serial adapter and this resolved (for Arduino IDE) needing to manually ground GPIO0. However, the ESP32-CAM module I was using did not expose the Reset signal. What I found is that not all ESP32-CAM modules are created equal! I swapped for another module that did expose Reset and connected that to the RTS output of my serial adapter. These two changes made the module programmable using the Arduino IDE without manual reset or GPIO0 grounding.

Unfortunately, flashing from PlatformIO (using the same serial) did not completely work. The flashing worked but the module is not being reset after programming is done. I need to investigate a littel more, but this does look like a PlatformIO problem.

Will report back later.

@maxgerhardt Yes the issue is from PlatformIO. I placed my oscilloscope on the Reset and GPIO0 signals and observed them when the flashing was done with the Arduino IDE. I saw what I expected from both signals, however when the PlatformIO “Upload and Monitor” command was used, the signals look right at the start, however, when the Monitor was started both Reset and GPIO0 were being held low.

In fact the issue appears to be the “Monitor” command of PlatformIO, after a simple “Upload” the Reset and GPIO0 signals appear correct.

Not sure where to investigate further, advice would be much appreciated.

I have not yet done the same test in PlatformIO with ESP-Prog and JTAG. Will do that later.

@maxgerhardt So, I switched to using the ESP-Prog JTAG debug interface and I am able to start debugging, set breakpoints, and step the simple blink sketch.

However, the “Monitor” command still places the target board into Reset with GPIO0 also low.

So I am convinced this is a bug in PlatformIO. I would love to dig further but I am just not sure where in the PlatformIO codebase to even begin looking.

Are there documents that would help me understand where to begin looking. Having come this far I would really like to continue digging into the issue.

The DTR/RTS line when the Monitor is open can be controlled with Monitor options — PlatformIO latest documentation, see e.g. Noob stuck on ESP32-CAM+MB with PIO/vscode - #5 by maxgerhardt

@maxgerhardt Excellent … I will try that later, thanks for the continued help :slight_smile:

@maxgerhardt Many, many thanks. I added control of the Monitor Initial State dor RTS and DTR and now with my simple test program I am able to Upload, Monitor, and Debug the code using ESP-Prog.

I am going to try and find some time to write a blog post on the setup, I am sure it will be useful to others trying to write custom code for the ESP32-CAM.

Excellent Community help!

@maxgerhardt Sorry to trouble you again but the use of ESP-Prog seems very unreliable. This afternoon I cleaned up the breadboard that connects the ESP-Prog (JTAG and Serial) to the ESP32-CAM. Initially all was looking good, “Upload and Monitor” seemed to work fine. I tried to use “Start debugging” and the startup failed. Just to double check the JTAG and Serial connections I tried to do “Upload and Monitor” again and that now fails. I have power-cycled the ESP-Prog and the ESP32-CAM several times, also I have restarted VSCode, by the problem remains, I cannot “Upload and Monitor” my very simple sketch.

Here is the task output:

*** [upload] Error 1

Can you reduce adapter speed a bit? Add debug_speed = 500 into the platformio.ini.

I can certainly try that; however, it is working again now. I switched to Arduino IDE to check if it was able to upload the code and it did right away. When I switched back to PIO it has worked since.

Next time it occurs I will lower the debug speed. Although I suspect that is not the issue.

I started work with PlatformIO again this afternoon and while Upload and Monitor is working the first time I tried to start debugging it failed like above.

I added the line “debug_speed = 500” to platformIO.ini, but this did not resolve the issue.

Running the simple sketch with the Arduino IDE did not resolve the issue this time, that must have been a coincidence.

Here is the debug log I see:
