hello everyone, this is the first time in my life I have encountered such an error. I have an esp32 camera programmer card in my hand, as you can see in the picture, I made the connections perfectly, but every time I try to upload code, I get this error code. there is only a reset button, i'm tired of dealing with it for days, don't spare your help spartans 
Did you press the button when the serial monitor shows ...___...___...___...?
Sorry I cannot read your text, you can copy it then paste it into your message. As for code please use code tags as explained in the forum guidelines.
connecting on serial monitor.................................. when I saw the text I pressed the reset button but it didn't work.
please post your code.
please press the <code> icon and copy/paste it into the highlighted area

sorry. i misunderstood that this error is during the upload
which port is selected under the Arduino IDE Tools-Port tab?
yes ı am getting this error while uploading code. Port 3
is "COM3" the port the Arduino is connected to?
is COM3 the correct port?
yes its correct i think the problem is this card is espressif card like i said i tried everythink so i cant find the where is the problem
notice you're using IDE 2.1. i'm prefer the older version
i tried changing the upload speed and setting the board to Wrover for my ESP32-WROOM-32D and it still worked.
the default upload speed is 921600
don't know what else to tell you
ok i will try and let you know
I am using 1.8.19; this may look different in 2.1:
fire up the IDE
No board connected: Tools >> Port and note the ports available. typically ttyUSB0 and ttyS0
Connect ESP board
Tools >> Port and note the new port available. that new port was created by the UART chip in the ESP. connect to that new port
Serial Monitor, at 115200
press the reset on the ESP
if you see a wall of gobbledygook, you're in
the following is what i see if the COM port is not set correctly, so i think there's some other issue

Error opening serial port 'COM4'.
I'm having the same issue. I've tried on both Ubuntu and macOS, neither have worked. I've checked the serial port and it disappears when I unplug it and reappears when I plug it back in, so that's probably not the issue. I'm getting zero communication on serial monitors. Is it a hardware issue? @burak60 did you buy your board from HiLetgo on Amazon?
Form the picture you have posted a lot of details can not be seen:
- where is the USB-virtual-COM-Port-adapter-chip?
- what type of USB-virtual-COM-Port-adapter-chip is it?
what else than the USB-socket do you need as connection for uploading code?
It can not be seen if this board has a reset and another second button
best regards Stefan
don't post screenshot graphics post text like shown in this tutorial
edit: are you really expecting that other users will re-type a foreign language error-message and translate it ?
You are posting in the english speaking / writing forum this means your communication has to be in english
