Programming ESP32: how its done and issues that might occur [solved]

In this video I show how to program an ESP32 (ESP32-WROOM-32D) with the Arduino IDE and discuss the following three errors that can occur:

NOTE: please make sure you restart the Arduino IDE after board installation.

NOTE2: make sure that the com port of the ESP32 shows up in the windows device manager. In some cases you might need to install these drivers:

Error 1:
A fatal error occurred: Failed to connect to ESP32: Timed out waiting for packet header
* Solution: press "Boot" for at least one second when programming in the connection phase

Error 2:
A fatal error occurred: Timed out waiting for packet content
* Solution: replace USB cable

Error 3:
USB device not recognized: The last USB device you connected to this computer malfunctioned, and Windows does not recognize it
* Solution: replace USB cable

Addition : if you don't want to press the boot button when uploading you can use capasitor elcho 1uf 16v/10uf 16v and connect to ground and en

I think the reason why you need to have the right USB cable is that it must transfer data as well as power. Many USB cables are power only

BOOM! Finally! Thanks loads! press boot x2 after compiling ':]

I went through about 5 cables trying to get mine programmed, but finally got a good cable and programmed them all. Short thick usb cable.

Thank you so much brother i m trying to search the solution of this problem since 4 days bt now it fixed thank you so much🥳🥳

FYI on Mac m1, you may need to quit and reopen arduino ide after pasting the link for the board installation to show up

Do you press and hold down the boot while trying to upload after it compiles, Or do you press and release the button while trying to upload after it compiles?

why when I reset the esp it still doesn't want to connect to wifi? and the serial monitor reads like random letters and numbers?

Thank you so much for this tutorial. It helped me when I was working on ESP32 WROOM. Now, I'm working on ESP32-C3 and having same issue only this time the fatal error is No serial data received. Do you have any clues how do I sort this out? Thanks in advance

The error comes as “ A fatal error occurred : Packet content transfer stopped (received 8 bytes) “ Can you please provide a solution asap, I have been banging my head and brainstorming still nothing is working. Also, I’m already using a 10uF capacitor between En and ground still the adamant error persists. Please provide a solution

Thank you for your tutorial bro, But I'm facing an other error like this "A fatal error occurred: MD5 of file does not match data in flash!"
how to solve this error please help me on this bro
thamk you in advance

I'm getting a fatal error: failed to connect to esp32: download mode successfully detected, but getting jo sync reply: the serial tx path seems to be down

[edward]

Mine is still giving issues. Even with capacitor and different cables used, the IDE does not go past "Connecting Any other solutions I should try?

The WiFi LED is not switching off and am not able to boot the ESP32 using the boot button.

Hello: I'm working with Xiao esp32 light sleep: I put this code at the beginig of the loop function. Now I cannot re-program the device. I've tryed by pressing the boot button while connecting USB-c; but fail to program the Xiao Esp32... I cannot make the device enter in download mode: A fatal error occurred: Failed to connect to ESP32-C3: Wrong boot mode detected (0x1)! The chip needs to be in download mode.
Please some help.

I have the wesmos d1 r32 and I had the same issue until I finally was able to upload it but then the circuit does not do any action at all. Like I've made a simple code for led light and nothing happens.

[orangepoof]

how about error: Failed to connect to ESP32: Download mode successfully detected, but getting no sync reply: The serial TX path seems to be down. I try lot of way until i buy new usb cable and still didn't work, press and hold EN & Boot button, restart the ide, laptop etc. Still didnt work, help
