The precompiled binaries don't play well with `cygwin` so it is better to build them ourselves. The procedure for the precompiled binaries is included at the end of this guide. + +### Build and Install the `libusb` +The `dfu-programmer` requires `libusb` so that it can interact with the USB system. These repos must be bootstrapped in order to create an appropriate `./configure` and `Makefile` for your system. +``` +$ cd ~/src +$ git clone https://github.com/libusb/libusb.git +$ cd libusb +$ ./bootstrap.sh +$ ./configure +$ make +$ make install +``` + +### Build and Install the `dfu-programmer` +``` +$ cd ~/src +$ git clone https://github.com/dfu-programmer/dfu-programmer.git +$ cd dfu-programmer +$ ./bootstrap.sh +$ ./configure +$ make +$ make install +``` + +Verify the installation with: +``` +$ which dfu-programmer +/usr/local/bin/dfu-programmer + +$ dfu-programmer +dfu-programmer 0.7.2 +https://github.com/dfu-programmer/dfu-programmer +Type 'dfu-programmer --help' for a list of commands + 'dfu-programmer --targets' to list supported target devices +``` +If you are not getting the above result, you will not be able to flash the firmware! + +###Install the USB drivers +The drivers are included in the windows binary version of [`dfu-programmer` 0.7.2](http://iweb.dl.sourceforge.net/project/dfu-programmer/dfu-programmer/0.7.2/dfu-programmer-win-0.7.2.zip). +``` +$ cd ~/src +$ wget http://iweb.dl.sourceforge.net/project/dfu-programmer/dfu-programmer/0.7.2/dfu-programmer-win-0.7.2.zip +$ unzip dfu-programmer-win-0.7.2.zip -d dfu-programmer-win-0.7.2 +``` + +or + +The official drivers are found in [Atmel's `FLIP` installer](http://www.atmel.com/images/Flip%20Installer%20-%203.4.7.112.exe). Download and then install `FLIP`. Upon installation, the drivers will be found in `C:\Program Files (x86)\Atmel\Flip 3.4.7\usb`. + +Then, from an **administrator-privileged** `Windows` terminal, run the following command (adjust the path for username, etc. as necessary) and accept the prompt that pops up: +``` +C:\> pnputil -i -a C:\cygwin64\home\Kevin\src\dfu-programmer-win-0.7.2\dfu-prog-usb-1.2.2\atmel_usb_dfu.inf +or +C:\> pnputil -i -a "C:\Program Files (x86)\Atmel\Flip 3.4.7\usb\atmel_usb_dfu.inf" +``` + +This should be the result: +``` +Microsoft PnP Utility + +Processing inf : atmel_usb_dfu.inf +Successfully installed the driver on a device on the system. +Driver package added successfully. +Published name : oem104.inf + + +Total attempted: 1 +Number successfully imported: 1 +``` + +Alternatively, the `Windows` driver can be installed when prompted by `Windows` when the keyboard is attached. Do not let `Windows` search for a driver; specify the path to search for a driver and point it to the `atmel_usb_dfu.inf` file. + +##Building and Flashing the Planck firmware! +If you did everything else right. This part should be a snap! Grab the latest sources from `github`, make the Plank firmware, then flash it. + +###Build Planck and Load the Firmware +``` +$ cd ~/src +$ git clone https://github.com/qmk/qmk_firmware.git +$ cd qmk_firmware/keyboards/planck +$ make +``` + +Make sure there are no errors.

(For me, it is `C:\cygwin64\home\Kevin\src`), extract the files, move `dfu-programmer.exe` to `~/local/avr/bin`. Most obnoxiously, the `libusb0_x86.dll` and `libusb0.sys` need to be moved from `./dfu-prog-usb-1.2.2/x86/` to a directory in the `Windows` `PATH` and the `cygwin` `PATH`. This is because the `dfu-programmer` binary is `mingw` based, not `cygwin` based, so the `dlls` do not cooperate. I achieved acceptable pathing by moving the files to `C:\cygwin64\home\Kevin\local\avr\bin` Then, in a `WINDOWS` command prompt running (Adjusting your path for username, etc. as needed): +``` +C:\> set PATH=%PATH%;C:\cygwin64\home\Kevin\local\avr\bin +``` + +Then, rename `libusb0_x86.dll` to `libusb0.dll`. + +You can tell that you were successful by trying to execute 'dfu-programmer' from the 'cygwin' prompt: +``` +$ which dfu-programmer +/home/Kevin/local/avr/bin/dfu-programmer + +$ dfu-programmer +dfu-programmer 0.7.2 +https://github.com/dfu-programmer/dfu-programmer +Type 'dfu-programmer --help' for a list of commands + 'dfu-programmer --targets' to list supported target devices +``` + +If you are not getting the above result, you will not be able to flash the firmware! +- Try making sure your `PATH` variables are set correctly for both `Windows` and `cygwin`. +- Make sure the `dll` is named correctly. +- Do not extract it with `cygwin`'s `unzip` as it does not set the executable permission. If you did it anyway, do `chmod +x dfu-programmer.exe`. +- Still have problems? Try building it instead. + + +##Debugging Tools + +These tools are for debugging your firmware, etc. before flashing. Theoretically, it can save your memory from wearing out. However, these tool do not work 100% for the Planck firmware. + +### `gdb` for AVR +`gdb` has a simulator for AVR but it does not support all instructions (like WDT), so it immediately crashes when running the Planck firmware (because `lufa.c` disables the WDT in the first few lines of execution). But it can still be useful in debugging example code and test cases, if you know how to use it. + +``` +$ cd ~/src +$ git clone git://sourceware.org/git/binutils-gdb.git +$ cd binutils-gdb +$ mkdir obj-avr +$ cd obj-avr +$ ../configure --prefix=$PREFIX --target=avr --build=x86_64-unknown-cygwin --with-gmp=/usr/local --with-mpfr=/usr/local --with-mpc=/usr/local --disable-nls --enable-static +$ make +$ make install +``` + +### `simulavr` +`simulavr` is an AVR simulator. It runs the complied AVR elfs. `simulavr` does not support the `atmega32u4` device... it does `atmega32` but that is not good enough for the firmware (no PORTE and other things), so you cannot run the Planck firmware. I use it to simulate ideas I have for features in separate test projects. + +This one is a major pain in the butt because it has a lot of dependencies and it is buggy. I will do my best to explain it but... it was hard to figure out. A few things need to be changed in the 'Makefile' to make it work in `cygwin`. + + +``` +$ cd ~/src +$ git clone https://github.com/Traumflug/simulavr.git +$ cd simulavr +$ ./bootstrap +$ ./configure --prefix=$PREFIX --enable-static --disable-tcl --disable-doxygen-doc +``` + Edit `src/Makefile.am` now so that `-no-undefined` is included (I did this by removing the SYS_MINGW conditional surrounding `libsim_la_LDFLAGS += -no-undefined` and `libsimulavr_la_LDFLAGS += -no-undefined \ libsimulavr_la_LIBADD += $(TCL_LIB)`. Also, `$(EXEEXT)` is added after `kbdgentables` in two places. + +``` +$ make +$ make install +``` + + +TODO: +- git repos for all sources +- command line magic for cygwin setup +- better options for `dfu-drivers` |
