Getting Nightly Builds for AVRDUDE

Here you can find the latest development builds of AVRDUDE for various operating systems and architectures.

Note: The executables provided on this page are development builds and may not work as expected.
If you want to download AVRDUDE, you should use the AVRDUDE Releases instead.

Windows (static linking to dependancies)

1. Using VS2022 MSVC toolchain

• avrdude-msvc-x64.zip (recommended for most users of Windows)
• avrdude-msvc-x86.zip
• avrdude-msvc-arm64.zip

Known limitation for the above MSVC build

• https://github.com/avrdudes/avrdude/issues/1552 (no libserialport support)
• https://github.com/avrdudes/avrdude/issues/1253 (slow speed when using arduino-ft232r or similar programmer)
• https://github.com/avrdudes/avrdude/issues/968 (not working with USB Composite Device programer like USBASP with the FW from https://github.com/dioannidis/usbasp)
• https://github.com/avrdudes/avrdude/discussions/1440 (no support of CH341A)
• https://github.com/avrdudes/avrdude/discussions/1956#discussioncomment-13017813 (no support of PICkit 5)

2. Using MSYS2 mingw toolchain

• avrdude-mingw-x86_64.zip (recommended for Windows users if the msvc x64 version does not work well for you under Windows)

Known limitation of the above MSYS2 mingw build

• You will have to use Zadig to swtich the FTDI vendor driver if you use libftdi based programmer (eg: ft232h, ft2232h, arduino-ft232r)
• https://github.com/avrdudes/avrdude/issues/1271 (timeout may be more likely to happen for urclock in terminal mode)
• https://github.com/avrdudes/avrdude/issues/1594 (not working with SNAP and PICKit 4 under Windows 7)

Linux (dynamic linking to dependancies) -- please do not use this build in general as it may only works for later version of Ubuntu.

• avrdude-linux-i686.zip
• avrdude-linux-x86_64.zip
• avrdude-linux-armhf.zip
• avrdude-linux-aarch64.zip

macOS (dynamic linking to dependancies) -- please do not use this build in general as it may only works for later version of macOS.

• avrdude-macos-x86_64.zip

Linux, macOS and Windows (static linking to dependancies)

Using the Arduino avrdude-packing CI script to be compatible with many Linux distros and macOS versions. This is recommended for most users of Linux and macOS, as well as for Arduino distros under Windows.

• dist_Linux_32bit.zip
• dist_Linux_64bit.zip
• dist_Linux_ARM64.zip
• dist_Linux_ARMv6.zip
• dist_macOS_64bit.zip
• dist_Windows_32bit.zip

Known limitation for the above build

• https://github.com/arduino/crossbuild/issues/13 (no libserialport support as of now)
• You will have to use Zadig to swtich the FTDI vendor driver if you use libftdi based programmer (eg: ft232h, ft2232h, arduino-ft232r) under Windows
• https://github.com/avrdudes/avrdude/issues/1271 (timeout may be more likely to happen for urclock in terminal mode)
• Notes for the macOS binary: The macOS binary is static linked to dependency libraries. You may need to follow the guide below to allow the execution of the binary under macOS. https://support.apple.com/en-sg/guide/mac-help/mh40617/mac
