Hi.
What is the ESP32 core version you’re using? Go to Tools > Board > Boards Manager, search for ESP32, and then check the version. Try to update to the latest version and check if anything changes.
Regards,
Sara

thank you, I have the esp32 2.0.11 version. I have studied the arduino forum link and saw a number of persons having the same problem. You mentioned in the tutorial that there can be problems with the 2.0 Arduino IDE. Would this be one such problem? I noted that in the forum there were persons with EPS32 S3 that had the same problem so that made be think it was not a problem with the IDE version not being legacy.

Hi.
What options are you selecting in the Tools menu:
 I’ve selected “Ai Thinker ESP-32 cam” board. Flash mode “DIO”. Partition Scheme “Huge APP (3Mb…)”
Did you select that too?
Can you share your code with me so that I can test on my boards?
Regards,
Sara

Thank you for your continued effort to ease my pain.
I’m using the recommended tool settings. with the Ai thinker ESP-cam, Flash Mode DIO, partition scheme “Huge APP…,” cpu frequency 240 mhz, core debug level “none,”  flash frequency 80 mhz, programmer esptool, core debug level “none”, erase all flash before sketch upload- “enabled,”
the code is from the recommended example.  Also I am using the 2.1.1 IDE.

Sarah, my apology.  I did comment out the esp-eye and uncomment the ai thinker in the code that i used and for which I  receive the error messages.  I sent a raw copy of code but have been making the required changes.
Do you use the new Arduino IDE or the legacy version?  I was reluctant to make that change in the IDE.
I am using the MB programmer and have ordered a FTDI to see if that helps.
 

Hi.
I just tested the example in File > Examples > ESP32 > Camera > Camera Web Server
I’m using Arduino IDE legacy version.
I selected AI-Thinker ESP32-CAM
Tools > Flash mode: QIO
Tools > Partition Scheme Huge App
I’m using the MB programmer.
I’m using the ESP32 core 2.0.10.
 
Everything works as expected.
 
Please try Arduino IDE legacy version.
 
Regards,
Sara
 
 
 

I also tried using Arduino 2.0 and it also works.
So, I’m not sure what might be causing the issue exactly,
But, try the other version of Arduino, just in case the 2.0 is not creating the partitions correctly.
Regards,
Sara

Sarah, Thank you for all your help.  After your last response, I decided to erase one of my computers down to the shell and start over.  Everything works now. I was having the same problems on both of my computers and also had an ESP32 dev module that had a faulty serial port connection.  Not sure if my problems were related to have both Arduino Create15 and Arduino IDE on my computer, or my Arduino sketch/library files on the cloud, or a corrupted file or my PATH  (on both computers) misdirecting,  or whatever.  Anyways, the VSCode with Platino and my Arduino IDE are working fine. On to my next mistake.
 

Great.
I’ll mark this issue as resolved. If you need further help, you just need to open a new question in our forum.
Regards,
Sara

hi sara i am siegmund and i am new. I have the same troubles and i tried all the suggestiions. but i still getting: “E(495) esp_core_dump_flash: no core dump partition found.” I dohave images, but no streaming images. So please do you have an other suggestion? thank you

Hi.
Please provide more info about the sketch you’re trying to run, the board you’re using, and the complete error message.

Sara
