This is caused by a generic connection error between your computer and the Arduino, and can result from many different specific problems. Here are some easy things that can often fix this error: Disconnect and reconnect the USB cable. Press the reset button on the board. Restart the Arduino IDE. Make sure you select the right board in Tools ► Board ►, e.g. ...

Another fix: Change Tools->Processor->Atmega 328P to Atmega 328P (Old Bootloader). Remind that the Processor option is only available when you select some specific Boards at Tools>Board. This worked for my Arduino Nano with CH340, using Arduino IDE 1.8.5 under Linux Ubuntu 17.10. Besides, this will probably happen if you use IDE 1.8.9 or newer ...

If you want an exact duplication of what the IDE does but want it driven from the command line, that's what Ino is for. The full Arduino build process involves copying a lot of files from a lot of places, and is generally not trivial to duplicate. If you're ready to let go of .ino files and the Arduino libraries, you get a much simpler toolset. avr-gcc ...

Unfortunately, it can also mean that you burned your microcontroller. Were you doing anything dangerous right before you tried to upload a new sketch? Is the microcontroller still working, with its previously loaded sketch?

I soldered wires to pads to be sure the connection was good, and used those wires for programming from the Uno. Then the programmer worked, without any edits to the command lines as posted in the question. I ran a few variations and was able to answer all my questions, and a few more besides: The "Yikes! Invalid device signature" error was being caused by ...

If none of the above steps work, try reinstalling Avrdude and the avr-gcc compiler. I had to do this after my Mega started suffering from this. If you installed Avrdude and avr-gcc separately, simply uninstall them. if not, you may have to reinstall the Arduino IDE. These steps will depend on your operating system.

In my case I hadn't wired the RTS pin of the FTDI chip to a capacitor which went to the RST pin of the Arduino Pro Mini. Once I installed this connection, I no longer got the error and I was able to upload code. Nick Gammon explains this in his forum. I've added a picture of where/how the capacitor should be placed.

I've had the same message. Every time it has been solved by selecting the right port ie USB under the menu Tools then Ports. Its a simple step but I always forget. I'll unplug the Arduino to stop the current program, plug it in again to my computer to upload the new program and get the error, panic, curse, and only then, remember.

From the OSX System Report we learn that your board is based on an SiLabs CP2102 converter (or workalike), but according to your question you installed the drivers for an entirely different product from FTDI (Arduino.cc has used FTDI in the past and CDC/ACM today, I don't believe they have ever used SiLabs so their instructions probably don't cover that, ...

After poking around for a bit more, it turns out my problem was the baud rate. I could make it work by setting it to 19200, just a little slower. Alternatively, you can modify the ArduinoISP sketch to enable higher baud rates. I used this post to enable 115200 baud and I was able to successfully use avrdude at the higher rates. Not sure how I missed this ...

AVRDUDE does not actually perform the write, it merely directs it. The actual writes are performed either by the bootloader or by the ISP firmware/hardware within the MCU itself. With the bootloader it depends on how itself is coded, but at worst it would finish off the flash byte or page or EEPROM page zero- or one-filled and then fail to communicate ...

The reset button does pretty much the same as unplugging the board and plugging it back in. It restarts your program from the beginning. The same thing happens when you program the board - the USB interface presses the reset button for you. That then enters the bootloader for a second or two so it can try and program it. When you reset the board the ...

I had the exact same problem. I tried installing the IDE in another laptop and uploaded the program from that laptop. Problem solved. Then I came back to my laptop, uninstalled the IDE and re-install it.. it started working. However, I wasn't satisfied because I couldn't find the source of the problem... so I tried running everything again the same exact ...

just to add to the list - some cheaper boards use CH340 chipset here is a blogpost on how to install the drivers on OSX http://javacolors.blogspot.ie/2014/08/dccduino-usb-drivers-ch340-ch341-chipset.html From that post: You can find drivers for this chip on the web site of the chinese manufacturer, here : http://www.wch.cn/downloads.php?name=pro&proid=...

Assuming the lock bits on the device haven't been set, sure. Simply prepare the Arduino for ArduinoISP, hook up the ATtiny45, and perform a read using AVRDUDE instead of a write (-U flash:r:foo.hex:i).

Do I need an oscillator installed just so I can wake it it up and tell it to not use an oscillator? Yes, yes you do. Pick up a 8-16MHz crystal (not an oscillator) and two 15pF capacitors and use very, very short wires to connect them to the chip as shown in the "System Clock and Clock Options" section of the '328P datasheet. You will then be able to ...

Please, Note that the Arduino IDE is behind on many of the tools. In this case avrdude and its conf file, along with avr-gcc First: .\arduino-1.5.6-r2\hardware\tools\avr\etc\avrdude.conf needs to support the m328 in addition to m328p. This can be done by either updating .\arduino-1.5.6-r2\hardware\tools\avr\bin\avrdude.exe to something like avrdude-6....

I had exactly this problem. If the ATtiny is set for external clock, then the ArduinoISP will not be able to program it without an external crystal. Connected a 16 MHz crystal and 2 capacitors and worked perfectly. (I was then able to set ATtiny to internal clock, remove the crystal, and then worked perfectly without the crystal.)

The cause is most likely the fact that you "... do not use any resistors, capacitors etc." Connect a 100nF capacitor between Vcc and GND. Connect a 10KΩ resistor between RESET and Vcc.

To preserve the bootloader, you should use the -D option in the ISP command line just as it was used in the bootloader upload command line. This will disable usage of full-chip erase. I expect you would end up with something like avrdude -c avrisp2 -p atmega328p -D -U flash:w:_build/image.hex However, it is important to add something which I overlooked ...

After much frustration in trying things, I came across this forum post which advised: sudo systemctl stop ModemManager.service If this works, disable the service from starting next boot: sudo systemctl disable ModemManager.service It seems like setting ENV{ID_MM_DEVICE_IGNORE}="1" in a udev rule is insufficient.

I uninstalled the IDE and drivers etc, installed it all again, then I ran the Arduino IDE as an administrator and set to run compatibility as windows 7 (I'm currently using 10). I also changed the programmer to AVR ISP (I don't think this matters, but I changed it anyway). All is working again... hopefully, this can help someone else out too.

For people using Linux Mint I found that by selecting the "TTY SO" port instead of the one labeled "Arduino" it would work (I can't tell you exactly because I don't have that computer in front of me right now). Then the next time I used the Arduino I again got the same message so I switched back to the "Arduino" port and it has worked that way ever since. ...

The bootloader on an arduino is just a piece of software written to enable you to update your sketches using the usb connection. Without the bootloader you can't upload sketches using just the arduino ide. More information about the bootloader can be found here: http://arduino.cc/en/Guide/Environment?from=Tutorial.Bootloader Look under the heading entitled ...

You cannot set the fuses using the Arduino bootloader, since they cannot be self-programmed. You must use either serial or parallel programming via ArduinoISP or an external programmer to set them. Since the chip is configured to use an external crystal you must either connect a crystal up to the chip appropriately (see sections 9.3 or 9.4 of the datasheet) ...

Short answer: I'm afraid you can't do it with Arduino IDE 1.0.5. Long answer: First of all, be aware that -B20 does not specify the baud rate but the bitclock period (in us); this is specific to stk500v2 programmer. Normally, enabling your programmer should only be a matter of adding it to the list of programmers known by Arduino IDE; that list can be ...

This is not an error. AVRDude is running with the Verbose flag on. Verbose in English means: using or expressed in more words than are needed. In the Arduino IDE:


3

Yes, it does. As can be seen in the "USART" section of the datasheet the baud rate is generated directly from both fosc (aka FCPU) and the value contained in UBRR. The tables at the end of the section gives the appropriate value for UBRR for a given CPU frequency, desired bit rate, and state of the USART clock doubler.

Your log is showing that communication is failing right away (avrdude never gets a proper response). This can mean that the VCC is not resetting there is no bootloader installed there is some other defect You can test case is by manually hitting the reset switch around the time that avrdude starts. If the necessary pins are available, you can exclude ...
