I have been working with the Arduino system with an Arduino Uno chip for a while, but I recently came upon a problem I cannot solve. The problem is that whenever I attempt to upload a new program to my chip, I get the following error:
avrdude: stk500_getsync(): not in sync: resp=0x00
I have done some research, and I have tried everything that people have suggested. I have checked the COM port, checked the chip type, checked the component installations, updated the FTDI drivers, hit the reset button, tried the latest Arduino software, and yes, I have even made sure the board is plugged into the computer.
Earlier this year I had absolutely no problem uploading code to my board, and almost nothing has changed since I last tried it. The only thing that has changed is the cable I have used to upload the programs, and I have tried several different cables as well. Could it just be a batch of bad cables? This seems unlikely. I have also tried uploading code onto different boards, with the same result.
This is getting quite frustrating, as I really want to continue working on my projects. However, that will not happen if I cannot even print "Hello World!" to the serial monitor.
I am running on a 32-bit Windows 7 machine. Any suggestions to solving this would be greatly appreciated.
If you are expecting a normal upload using Serial then you should ensure your preferences are not set to "Upload using programmer" and that you are not selecting "Upload using programmer" from any of the Arduino menus.
EDIT
If you have not overridden the programmer then you must have the wrong board selected on the tools menu boards list. lpt1 in the error message is not what the Uno uses.
It turns out that the problem was the FTDI cable I was using. I tried a bunch of different cables until I found one that works, and now uploading occurs without any problems.
check the board you have selected in tools-> board . If you selected wrong board error comes as above. If right board being selected still getting same error , then it is definitely boot loader crashed error. You need to upload boot loader.
Sometimes parts connected to digital pin 0 and 1. The parts interfere communication between the computer and arduino so I recommend this procedure.
Check something is connected to D0 and D1.
If something is connected, unplug those.
Upload the sketch.
Plug parts removed at step 2.
your arduino maybe not uno, change board to duemilanove.

I tried to flash an ESP32 but I didn't succeed, I tried with esptool.py and Arduino IDE. I tried to press the boot button and reset but it didn't work. Here is the error:
A fatal error occurred: Failed to connect to ESP32: Timed out waiting for packet header
If using the Arduino IDE, try lowering the upload speed (Tools/Upload Speed). Lowering mine from 921600 to 460800 did the trick.
First ensure that you are in download mode:
Start the serial monitor and set the speed (mine is 115200).
While pressing the "boot" button, press and release the "en" button (your buttons may be labeled differently).
You should see something like this on the serial monitor:
waiting for download
Now start the upload
My development machine, a 2013 iMac is connected via USB to the USB-c port on my ESP32 Dev Module. Apparently the iMac's USB or ESP32 board's USB cannot keep up at the 921600 upload speed.
DISCLAIMER! May not be correct answer but may help to save time for someone.
Quick answer if you do not want read my experience: Disconnect all wires from pins and try uploading again! It may help.
I came across with the same error and could not figure it out. I first thought that something is wrong with the code, because it happened after I edited working code while figuring out where to connect what pin 😀. I also wasn't able to upload simple HelloWorld after it happened with connected wires. But then I disconnected all my wires from the board and the upload works fine.
I can not figure out the WHY factor but I think it must had been the input/data pin I was using, in my case D13. I have the DevKit with fewer pins. Maybe someone can comment why connected pins may make the error come up?
To make your ESP32 board go into flashing/uploading mode automatically, you can connect a 10 μF electrolytic capacitor between the EN pin and GND. When I had the same problem, when I followed this advice, the problem was solved.

espressif/arduino-esp32 - issue
On some AliExpress-like ESP32s you have to press the boot button in order to upload your sketch.
If you are watching the Arduino IDE console ouput and Connecting ... appears, you have to press the boot button for approximately 2 seconds until the console output changes.
Try to do this one after the other
Press the boot button when press uploading button until it write the code.
Try disconnect esp32 from the board/header/pcb that you are using right at the time.
Disconnect any other connection that your esp32 might have.
Do not connect to anything even your hand if possible.
Try put it in something that doesnt have a moist surface. look pic number 3.
MY CASES(30 pin version):
Case 1: I dont know why. I was connecting the pin to a female header it doesnt work and sometimes it just work like that. look pic number 1.
Case 2: when Im holding esp32 on my hand sometimes it wont work then i put it on my table and another time it doing well.
Case 3: pressing boot button when uploading it helped sometimes, and the other time it just work like it should.
Case 4: when it connected to pcb its simply just wont work, but when disconnected boom it work like nothing ever happen. look pic number 2.
Maybe just maybe something with capacitive or something like that (just assuming because number Case 1). hope that will help you out.

This technique definitely working
Goto Tools > programmer, Select ISP and Upload Your Code.
if you can't see any programmer, then download 1.8.12 version.
https://www.arduino.cc/en/software/OldSoftwareReleases
With Arduino IDE
Make sure the Com port is selected under Tools menu. My experience with ESP32 is Com 5.
If it is not available as an option, try changing USB ports and/or re-select Tools - Board - ESP32 dev module.
Watch the "Compiling Sketch" window.
Press the "Boot" button as soon as you get the red message "Serial port Com 5" You can release the button as soon as it starts to upload.
If this doesn't work,try plugging into another USB port.
The Reset button only resets the uploaded sketch to re-initialise and has nothing to do with the uploading.
Install expressif.exe and port drivers,connect the port and flash the esp32 ,upload the code using ardiuno,solve the error
in my case buttons are new but not shorting properly as multimeter showed ..opened both scratched resoldered and all working
Changing by upload speed from 921600bps to 115200bps fixed it. No need to press any buttons.
Just download the drivers x)

FTDI: FTDI Virtual COM Port Drivers
I'm trying to do a DFU program upload via Arduino for an STM32F401CC. I'm using CubeProgrammer to upload the compiled bin and verify the contents of the STM32's flash is being written starting at 0x8 -- it's all there. I'm using a jumper to pull B0 high and am verifying it shows as STM32 BOOTLOADER in the device manager, then I'm disconnecting it. Everything shows that the program is upload correctly, but my program isn't actually running (make onboard PC13 LED blink). I'm using a board I got off amazon but verified the STM32F401CC is genuine. Is there something I'm missing? I'm coming over to ARM after years of using the ESP32.
I had couple bought and both the same problem,as yours, supposingly they were fake ones and wrong batch,so port in arduino ide wasnt recognized and the same issue as above in stmcubeprogrammer. It was stm32401ccu6 gh27a batch 103, only way was flash with full erase (manually didnt work only automatically in stm32cubeprogrammer ) possible but after each download code to mcu in arduino IDE i couldnt download any more sketches on it and had to upload new firmware / bootloader again and it didnt finish i had to press stop button in stmcube programmer during burning bootloader so trash, cheap peace of all kind of problems, i had to read the chineese documentation From WeAct on git because those with HID bootloader was just crap bad english , so more timre carefully didnt make even sense, so finally figure out how to flash finally bougt same chip 411 and it worked but Arduino ide sketch led didnt Blink another piece of cheap clone, 411ceu6 batch 106, at least could upload firmware sucesfully in stm32programmer but Arduino sketches didnt work , i had one 411 already from different manufacturere and didnt have these issues, and next time i will give it last try with WeAct orig chineese manufacturer which makes suposedly only original nonfake Stm32f411ce ver 3.0 product on aliexpress and they sell since 2022 411ceu6 batch 014 allegedly its only one which should not give all kinds of issues As they state on their git. Had anyone same problem solved to finally blinking led in arduino ide? It even didnt switch the build in on PC13 but i could measure 3,1V on that pin to ground, and everytime i burn the orig Or hid bootloader The led fades in and out, its a mystery to me really whats going wrong, someone on forums wrote issues with timer, it has to be sth with arduino ide 1.8.19 or stmduino , then noticed in board manager i have../raw/master/package_stmicroelectronics_index.json in preferences arduino ide and stated there as depreciated so i there was srated i shall be using raw/main/package_stmicroelectronics_index.json Oh my thing So i changed the word master into main and typed in Board manager STM32 MCU based boards and installed actual version 2.2.So instead of chaos just be patient and check literally everything, arduno could pop up message that mcu package depreciated but didnt ;) oh my...suddenly surprice, i need check yet if all worked and i just underwent wrong rumors, so no, it has 1,20V on PC13 diode doesnt blink with blink sketch only after bootloader upload fading, i hate such a job and bought 3 and all of them the same. Doesnt work eiter Led_buildin nor pc13, It was swg method, if i set led high and upload via serial i measure 1,9v and if I set led low i measure 1,3 v with Vin 5V and voltage drop ,5v results in 4,45v complete rambazamba , so i start tombelieve these boards are fake anyone similar or same experience?
i got a brand new Teensy 3.2 with the blinking LED programm on it.
When I now tried to upload another programm on the teensy, Arduino says:
Teensy did not respond to a USB-based request to automatically reboot.
Please press the PROGRAM MODE BUTTON on your Teensy to upload your sketch.
The automatically starting window of Teensy, doesn't give me a chance to (for example) reboot the Teensy as well, so something of the connection seems to be wrong or something, but what...
Even if I mannualy press the pushbutton, it's still not possible to upload something. Any ideas why?
I have encountered this problem twice. The first I tossed out the board. This time, when I power it, it runs the last program I burned on it, but when I try to program it again, the LED stops blinking and everything stops.
The claim that it might not be a data cable is not reasonable, because how can it stop the current program unless it was told to. I doubt very much that +5V can provide such commands.
I have tried different cables, different USB ports, rebooting my Linux box, reinstalling (twice), checking the pins on the Teensy and the cable... no clue.
It always boots up in the old app (I left the blinker running to indicate "liveness"). I had programmed a message to come out the hardware serial port. Could that have been the problem? Wait... Is there a way to set the baud rate on the USB? I wonder if that is the problem! --
Banner(void) {
Serial.begin(9600);
Serial1.begin(115200);
};
The example had me programming the USB serial! I bet that is the problem! Better yet, does anyone know what the protocol is for talking to USB serial commander?

I have an Arduino Uno and I am using arduino 1.0.5 IDE. I followed he procedures for bootloading an atmega328P-PU on a breadboard.
I uploaded the ArduinoISP sketch first, made the connections(using the External Oscillator) and then wired it up. Then, I selected the programmer as Arduino as ISP, selected the board as Arduino duemilanove w/ Atmega328P. Then I selected the correct serial port and clicked Burn Bootloader.
I got the following errors:
avrdude.exe: stk500_program_enable(): protocol error, expect=0x14,
resp=0x50avrdude.exe: initialization failed, rc=-1 Double
check connections and try again, or use -F to override
this check.avrdude.exe: stk500_disable(): protocol error, expect=0x14,
resp=0x51
How to solve this issue? Also, can I upload the bootloader directly by using it on the Uno in place of the original chip. If so, how?
to my understanding the error you have indicates a bad reading from the chip. I experienced that with chips that were either dead or not properly connected, especially to power supply.
You may find more detailed information in th tutorial : https://www.arduino.cc/en/Tutorial/ArduinoISP
Especially those things :
Note for Arduino 1.0: you need to make one small change to the
ArduinoISP code. Find the line in the heartbeat() function that says
"delay(40);" and change it to "delay(20);".
Select the items in the
Tools > Board and Serial Port menus that correspond to the board you
are using as the programmer (not the board being programmed).
Instead of arduino built-in boot loader just go through below link and it will be great for uploading boot loader and verifying board status info
I am replying you this because same issue I got long back and it saved me.
One more thing for arduino boot loader: for atmega328 you need to put capacitor between reset and gnd( in case you missed)
For gammon bootloader you don't need it.
Be Innovative.
For reset line you might me using 100nf(thats what stated in documentation )...but sometimes it doesn't work...try something like 4.7uf, 22uf or 47uf or close values
I had a similar problem and the issue was that my programmer was a bit slow, I used the -B flag for avrdude to slow down the bitrate and it started working, I set the -B20 and works like a charm every time, but I use the USBTinyISP programmer, not the stk500 one, so this might not work for you.
In case someone stuck at this as I did and nothing like changing the cap value helped. Make sure you are using your USB-TTL adapter in a 5v mode (obviously for a 5v powered chip). I always used it in a 3.3v mode in order not to accidentally burn my 3.3v chips and it always worked. Until today, I was trying to flash my custom atmega8 board and everything worked with the ISP but I was having a hard time using the bootloader and after half a day searching and trying different stuff the 5v setting to the rescue.
I am using arduino uno r3 board and arduino 1.6.5 on windows 8. When Itried to upload my program on ATMEGA328 microcontroller it is showing:
avrdude:stk500_getsync not in sync:resp=0x87.
help me to solve this error
This boils down to 3 problems usually..
The bootload on the chip is missing (unlikely if you purchased the board from Arduino).
The serial connection between the arduino and the computer is disconnected or interrupted.
You've simply selected the wrong board type or port when programming, and thus the IDE is searching for a signal that the arduino isn't coming back with.
This problem is most likely due to option 3, however it can occur in odd situations especially on the Arduino Micro where the board does all USB comms on chip and can be flooded by main without an appropriate delay to the point it can't communicate with the IDE. However this is just most likely a bad board selection or a bad port selection.
I've tried many things but this worked for me. If you have a working Arduino lying around (in my case Uno) you can use it as an intermediate in-system programmer (ISP).
Follow this guide to first load the ISP sketch into your working Arduino.
Once you are done, for your non-working Arduino, select from the Tools > Programmer menu and choose Arduino as ISP, and set Board and Processor accordingly. To program choose Sketch > Upload using programmer.
Hope this works.
I think the reason that this work is that it will bypass the CH340/FTDI chip, and all those synchronization issue. Given that that is your problem.
