2019年1月13日 · For avrdude to correctly work with USBAsp, I found the best to install the libusbK driver, at least under Windows 7. This way it works with both - the official avrdude build, and the one from the Arduino IDE. With the libusb-win32 or the WinUSB it works with one, but fails with another.

2018年2月2日 · and invoke avrdude as avrdude -c ft232r_mod -p m328p -P ft0 -U flash:w:led.hex (making sure to use ft0 instead of the serial port name). Alternatively, if you post what your FTDI board is, there may be an exposed pad for the DTR signal, like on Adafruit's FTDI Friend.

2023年1月25日 · avrdude.exe: verifying ... avrdude.exe: verifying ... avrdude.exe: verification error, first mismatch at byte 0x0000 0x00 != 0x0c avrdude.exe: verification error; content mismatch Note: before AVRDUDE gets to this point it reads the device signature and writes the hex files that I sent to it. Like normal.

AvrDude -> ArduinoBoard+ArduinoISP -> targetChip And I fail miserably to find proper instructions though I believe this is possible and perhaps even already explained somewhere. I could not find instruction mainly because keywords …

I had the same issue with an attiny25-20PU that had already a unknown program on. I copied the arduino command line for avrdude from arduinos upload output into a terminal, added at the end a -B and used different big numbers (32 48 64) and by good luck the 64 made the programming so slow that it worked - and from now on it worked without any -B option.

2017年11月9日 · avrdude -c usbasp -p t85 -B4 The -B4 is important and I tested successfully between -B4 and -B20. It slows down the clock and -B4 was the minimum for me to make it work. I had however chips that did NOT answer with -B4. To be conservative, I started with -B16.

The avrdude documentation doesn't tell the whole story. Fortunately the source is open , so we can peer beneath the covers. Essentially avrdude collects the command line arguments, packs them in a struct, and asks the programmer to initialise itself .

The -b parameter to avrdude specifies the baud rate for communication with the programmer. In contrast -B paramater specifies the speed of the actual programming, though I'm not entirely convinced that this is honored when using the ISP sketch.

2012年5月1日 · Whenever I've gotten the 'not in sync' error, it was related to my just missing the reset timing (or forgetting the reset entirely!). For my breadboard, and Eclipse/AVRDude, un-grounding the reset pin just before or at the same time as …

2014年12月21日 · I also had the problem: "avrdude: stk500_paged_load(): (a) protocol error, expect=0x14, resp=0x00. avrdude: stk500_cmd(): programmer is out of sync". Later given up. Then I used another USB cable (proper) instead of a thin USB cable supplied with a Pololu ISP for something else and I realized the cable I used with the Arduino Nano may be of ...
