Hi
I am quite new on PlatformIO and I try to upload through OTA to ESP32-CAM AI Thinker but it failed.
The invitation was sended but the uploading stops after 3%. For information, it worked fine on IDE Arduino.

Have you an idea to solve the problem?
Thanks
Please set the debug to level to verbose (docs), reflash the firmware normally and re-execute the OTA upgrade while looking at the serial output of the device. What does the device output?
Thanks for your response, I will try this in the few days and keep you informed
Hi
Here the serial output:

Please update the BasicOTA sketch (while adapting the WiFi credentials of course) to the device and retry the OTA. Is the log different now?
I think I will retry with arduinoIDE to check it is always OK
Is your firewall or antivirus program blocking outgoing connections from the python program? Can you temporarily disable it? Does it work in the Arduino IDE?
In fact I have the same problem on IDEarduino 
(but it worked before I shloud have reinstalled my ubuntu few weeks ago). So the problem is not PlatformIO. Moreover the complete log on serial port is this after:

I will check Firewall or antivirus
I found the problem 
The board should be set to:
- Board: "ESP32 Dev Module ,
- Partition Scheme: "Minimal SPIFFS (1.9MB APP with OTA/190KB SPIFFS)
- and PSRAM: "Enabled
And not AI Thinker ESP32-CAM! It is necesseray to have two partition set. The problem is that I know how to set this set in ArduinoIDE but not in PlatformIO…
Setting up partition tables in PlatformIO is documented.
As you can see from the Arduino-ESP32’s board.txt, using that partition scheme maps to using the following partition CSV file:
Thus you should try adding the line
board_build.partitions = min_spiffs.csv
in your platformio.ini
I tried to set
board_build.partitions = min_spiffs.csv
the uploading of my own sketch is OK but when the ESP is restarting it boots on an old sketch!!! The BasicOTA sketch…
Does the Arduino IDE behave in the same way?
No it is booting on the correct sketch on ArduinoIDE! I don’t understand. The config of ESP32 and especially partition’s configuration is not easy on platformIO… I keep it only because I like VisualStudio code’s editor… 
So what is your board set up as now in PlatformIO? Something like the following, I hope…
[env:ESP32-CAM]
platform = espressif32
framework = arduino
board = esp32dev
board_build.partitions = min_spiffs.csv
upload_protocol = espota
build_flags =
-DBOARD_HAS_PSRAM
-mfix-esp32-psram-cache-issue
On second thoughts, after looking at the configuration for both the esp32dev and the esp32cam… I don’t see why the esp32cam profile wouldn’t work, as long as you set the right partition scheme… i.e. the ESP32-CAM is set to huge_app.csv by default, and sets the PSRAM build_flags, so the following should work also.
[env:ESP32-CAM]
platform = espressif32
framework = arduino
board = esp32cam
board_build.partitions = min_spiffs.csv
upload_protocol = espota
Ok, I think I made mistake yesterday when I tested quickly and use an old platformio.ini file from an another project… 
So now it works with this platformio.ini file:
[env:esp32cam]
platform = espressif32
board = esp32cam
framework = arduino
lib_deps = GitHub - tzapu/WiFiManager: ESP8266 WiFi Connection manager with web captive portal
upload_port = 192.168.1.43
upload_protocol = espota
monitor_speed = 115200
board_build.partitions = min_spiffs.csv
@maxgerhardt @pfeerick Thanks for your help
