I am currently facing an issue where I have connect the debugger via USB to my laptop, power on its Atmel-ICE debugger with the CPU ATtiny13a. After clean and build project successfully, I didn't managed to debug it.
It resulted in the error: Failed to enable DW: Failed to enter programming mode. ispEnterProgMode: Error status received: Got 0xc0, expected 0x00 (Command has failed to execute on the tool)
I have tried to troubleshoot by checking the wiring connection. It shows connection to my laptop as the debugger lights up with green LED when i powered it up with 12V, and red LED lights up to show debugger has been connected.
Could it be the connection issue or failure in the chip or debugger board having issue?
Would like to have some advice on what I can do. Thank you so much!

I tried all the google solutions, It seems like RST button doesn't actually reset. Just red led blinking all the time, and no serial output or anything I'm working on Windows 10, ESP32 Dev Module ,on COM4 ,Default 4MB with spiffs (1.2MB APP/1.5MB SPIFFS), 240MHz (WiFi/BT), QIO, 80MHz, 4MB (32Mb), 115200, None.
I tried with different esp it works
Sketch uses 204738 bytes (15%) of program
storage space. Maximum is 1310720 bytes.
Global variables use 13416 bytes (4%) of
dynamic memory, leaving 314264 bytes for
local
variables. Maximum is 327680 bytes.

I normally upload at 921600. Your settings look perfect, it is working very well for me. Try the following -
If the Serial pins(Rx/Tx) are connected anywhere, disconnect/unplug them.
Keep the boot button on hold while it is trying to connect.
Change the USB port. If you are using hardware debuggers, zadig can mess things up.
I have faced similar issues, the above mentioned ones have always solved it. Choosing wrong board also results in this issue, I tried ESP-01, ESP-03 or other smaller boards with this setting and faced this. So make sure you are using exactly the ESP32 dev module and not anything else.
I had this problem, turns out I didn't have the proper USB driver installed.

Hope this helps someone in the future.
I have an ESP32-Cam AIThinker and everytime I try to upload (File > Examples > ESP32 > Camera), I always get this error everytime: A fatal error occurred: Failed to connect to ESP32: Timed out waiting for packet header.
I've been following YouTube tutorials but none just seem to work for me :(
Here are my upload settings. At the time of writing, I am using Arduino IDE 1.8.15 and esp32 board version 1.0.6.
I have tried:
Using FTDI232 to upload
Pinout Diagram
Using Arduino to upload
Pinout Diagram
Using ESP32-CAM-MB that came with the ESP32-Cam I bought.
Pressing the RST button while and before uploading (also waiting for the "connection" text to appear then pressing RST).
Switching between 3.3v and 5v, still the same error.
Switching between QIO and DIO flash mode.
Swapping RX and TX.
Though I didn't get any errors uploading using the ESP32-CAM-MB, I was stuck on this and it wouldn't show me IP to where I can access the camera.
I am new to this so please take it easy :)
This is what worked for me: Remove the GPIO0 and GND short after uploading the code and press the RST button.
Press the Reset (or Boot in some boards) button and keep it pressed until you see that the code is being written (uploaded) on the board.
I just installed the ESP32 library, and every time I try to upload a file to the ESP it gives me this error:

If you use the bare board check for
Serial monitor closed
3.3V stable voltage and
correct connection via FTDI/USB
if using a CP210x (driver 2019) or similar you can try lowering the baud rate for flashing to 115200 or/and
to pull EN to GND (If the board has a boot button then press this one) until the connect_____.....___ appears then release OR the magic sequence
Press and hold RESET / Press and release BOOT / Release the RESET
If you have hardware attached:
IO12 must be pulled low on power up as it is also the MTDI line. The device does have a weak pull down on IO12
See docu page 18 Figure 4If you are using it as I2C or similar you may have a pull-up connected. When removing the pull up resistor you could program it.
Recently I bought a esp8266 nodemcu for my project.
For running the blink code, I followed this tutorial esp8266 quick start.
But ended up with this :

I tried with different baud rate but failed.
Arduino IDE: 1.6.5 and 1.8.5
OS: Windows 10 and Ubuntu 16.04LTS
Update: Solved after using USB HUB.
The problem may come from circuit breakdown. I have this problem today and solved by following. Jump D3 (or GPIO00) to GND (if your PC still can see port). However, GPIO0 is set to OUTPUT/HIGH by default and may cause excessive current consumption. To prevent board fail, 1K resister may add between GPIO0(D3) and GND. Plug module power and upload program. Sometimes, please remember that you may need to unplug and plug module every new upload.
For another method,direct program to chip, use FTD232 (switch jumper to 3.3V) connect between FTD232 and NodeMCU like as Vcc(check it is 3.3V):3.3V , Tx:Rx, Rx:Tx, Gnd:Gnd, Gnd:D3. (you may use on board GND to D3)
Plug and upload. if the second method cannot work your ESP8266 IC may be gone.
As mention above, if your ESP8266 set GPIO0 as OUTPUT/HIGH, ground it may damage chip. Make sure that you
1) unplug power before ground GPIO0 (or add a resister)
2) power it and upload
3) remove GPIO0 when enter upload to prevent short out the output when program start to run.
First, you have to install the driver for the nodeMCU! You can get it here:
https://www.silabs.com/products/development-tools/software/usb-to-uart-bridge-vcp-drivers
And then go to control panel->devices and check if your system detects the nodeMCU.
Next go to preferences and add the board to Arduino IDE
Next disconnect and reconnect (just for confirmation) to verify if a led(blue usually) blinks upon connection.
After these steps, then go to Arduino IDE and select the board as ESP -12E module
Set the programmer as AVRiSP mk ll
And then compile and upload!
Recently I got my ESP 8266. It was running fine untill I hit the command AT+CIUPDATE for installing any OTA updates. The module is now unresponsive. It returns garbage values in the serial monitor when powered and connected to Arduino Mega.
Can any one help me out in this problem?
The binaries become corrupt due to heating, to restore it to its normal state, use any flasher tool to re-flash the firmware onto it.
