#Planck Advanced (but not too advanced) Cygwin Users Guide If you are a user of the Cygwin environment in Windows and want the freedom to use the latest tools available, then this is the guide for you. If compiling your own copy of the latest and greatest Gnu C compiler makes you super happy, then this is the guide for you. If the command line make you smile, then this is the guide for you.
This guide was written step by step as I went through the process on a Windows10 x86_64 based system. This should be generally applicable to to any Windows Environment with Cygwin.
#####Do not skip steps. Do not move past a step until the previous step finishes successfully.
based on avr-libc installation guide
###get the required packages Download the Cygwin Installer (x86_64 or x86_32) and install the default system plus the following if they are not already selected: -devel/gcc-core -devel/gcc-g++ -devel/flex -devel/git -libs/libglib2.0_0 -libs/libgcc1 -interpreters/m4 -web/wget
The following sources will be required: -get gmp (6.1.0) -get mpfr (3.1.3) -get mpc (1.0.3) -get binutils (2.26) -get gcc (5.3.0) -get avr-libc (2.0.0)
The dfu-programmer will be required to flash the new firmware
-get dfu-programmer (0.7.2)
The set of commands below will create a directory (~/local/avr) for the sources you compile to be installed on the machine and a directory (~/src) for these source files to be stored. The commands then download the sources of the needed packages and unpack them. note: the expand commands are different depending on if the packages are offered as a bz2 or gz archive
$ mkdir ~/local/avr
$ mkdir ~/src
$ cd ~/src
$ wget https://gmplib.org/download/gmp/gmp-6.1.0.tar.bz2
$ wget http://www.mpfr.org/mpfr-current/mpfr-3.1.3.tar.bz2
$ wget ftp://ftp.gnu.org/gnu/mpc/mpc-1.0.3.tar.gz
$ wget http://ftp.gnu.org/gnu/binutils/binutils-2.26.tar.gz
$ wget http://mirror0.babylon.network/gcc/releases/gcc-5.3.0/gcc-5.3.0.tar.gz
$ wget http://download.savannah.gnu.org/releases/avr-libc/avr-libc-2.0.0.tar.bz2
$ tar -xjf gmp-6.1.0.tar.bz2
$ tar -xjf mpfr-3.1.3.tar.bz2
$ tar -zxf mpc-1.0.3.tar.gz
$ tar -zxf binutils-2.26.tar.gz
$ tar -zxf gcc-5.3.0.tar.gz
$ tar -xjf avr-libc-2.0.0.tar.bz2
###setup build environment These commands will set up the install directory and the PATH variable, which will allow you to access your installed packages. note: if you close the cygwin terminal window, you will need to rerun these commands, they are not permanent
$ PREFIX=$HOME/local/avr
$ export PREFIX
$ PATH=/usr/local/bin:/usr/local/lib:/usr/local/include:/bin:/lib:/cygdrive/c/WINDOWS/system32:/cygdrive/c/WINDOWS
$ PATH=$PATH:$PREFIX/bin
$ export PATH
##The gcc required math library packages The following packages are required to be complied and installed in order to compile gcc. They are not available through the cygwin package system, so we have to make them ourselves. They must be complied in this order because each one depends on the previous.
###build and install gmp
$ cd ~/src/gmp-6.1.0
$ ./configure --enable-static --disable-shared
$ make
$ make check
$ make install
###build and install mpfr
$ cd ~/src/mpfr-3.1.3
$ ./configure --with-gmp-build=../gmp-6.1.0 --enable-static --disable-shared
$ make
$ make check
$ make install
###build and install mpc
$ cd ~/src/mpc-1.0.3
$ ./configure --with-gmp=/usr/local --with-mpfr=/usr/local --enable-static --disable-shared
$ make
$ make check
$ make install
##OPTIONAL Part You can build and install a brand new gcc or you can use the one supplied by cygwin. This will take about 4-5 hours to compile (It is a "native build", so it does the entire build 3 times. This takes a long while). I would skip it. ###build and install gcc on your machine
$ cd ~/src/gcc-5.3.0
$ mkdir obj-local
$ cd obj-local
$ ../configure --enable-languages=c,c++ --with-gmp=/usr/local --with-mpfr=/usr/local --with-mpc=/usr/local --enable-static --disable-shared
$ make
$ make install
###build and install binutils on your machine
$ cd ~/src/binutils-2.26
$ mkdir obj-local
$ cd obj-local
$ ../configure
$ make
$ make install
##End OPTIONAL Part
##Buliding binutils, gcc and avr-libc for the AVR system Now we can make the critical stuff for compiling our firmware, binutils, gcc, and avr-libc for the AVR architectures. These allow us to build and manipulate the firmware for the Keyboard.
###build binutils for avr
$ cd ~/src/binutils-2.26
$ mkdir obj-avr
$ cd obj-avr
$ ../configure --prefix=$PREFIX --target=avr --disable-nls
$ make
$ make install
###build gcc for avr
$ cd ~/src/gcc-5.3.0
$ mkdir obj-avr
$ cd obj-avr
$ ../configure --prefix=$PREFIX --target=avr --enable-languages=c,c++ --with-gmp=/usr/local --with-mpfr=/usr/local --with-mpc=/usr/local --enable-static --disable-shared --disable-nls --disable-libssp --with-dwarf2
$ make
$ make install
For building the avr-libc, we have to specify the host build system. in my case it is x86_64-unknown-cygwin. You can look for build system type in the gcc configure notes for the proper --build specification to pass when you configure avr-libc
###build avr-libc for avr
$ cd ~/src/avr-libc-2.0.0
$ ./configure --prefix=$PREFIX --build=x86_64-unknown-cygwin --host=avr
$ make
$ make install
##Install dfu-programmer
To install the dfu-programmer, we must get if from their website (no fancy command line tricks here, but this might work).
Copy this file into your cygwin home directory. (For me, it is C:\cygwin64\home\Kevin), 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/dfu-prog-usb-1.2.2/x86/ to a directory in the Windows PATH and the Cygwin PATH. I achieved this by moving the files in Windows Explorer to C:\cygwin64\home\Kevin\local\avr\bin Then, in a WINDOWS command prompt running:
C:\> set PATH=%PATH%;C:\cygwin64\home\Kevin\local\avr\bin
Adjust your path (for username) as needed. Also, libusb0_x86.dll needs to be renamed to libusb0.dll. Why must this be so hard? You can tell that you were successful this way:
$ 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.
-Do not try to extract it with cygwin's unzip as it does not set the executable permissions correctly.
####Install the USB drivers
These drivers are included in the dfu-programmer 0.7.2 (but you can get newer ones here) and allow the dfu to program the firmware. From an administrator-privileged Windows terminal, run the following command (adjust the path as necessary) and accept the prompt that pops up:
C:\> pnputil -i -a C:\cygwin64\home\Kevin\dfu-prog-usb-1.2.2\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
##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/jackhumbert/qmk_firmware.git
$ cd qmk_firmware/keyboard/planck
$ make
Make sure there are no errors. You should end up with this or something similar:
Creating load file for Flash: planck.hex
avr-objcopy -O ihex -R .eeprom -R .fuse -R .lock -R .signature planck.elf planck.hex
Creating load file for EEPROM: planck.eep
avr-objcopy -j .eeprom --set-section-flags=.eeprom="alloc,load" \
--change-section-lma .eeprom=0 --no-change-warnings -O ihex planck.elf planck.eep || exit 0
Creating Extended Listing: planck.lss
avr-objdump -h -S -z planck.elf > planck.lss
Creating Symbol Table: planck.sym
avr-nm -n planck.elf > planck.sym
Size after:
text data bss dec hex filename
18602 82 155 18839 4997 planck.elf
-------- end --------
If you don't, you did not build the firmware, and you will have nothing to flash. If you have the fresh clone from github, it was probably something in the install process, go check and see what didn't work and threw errors or what steps you might have missed.
But if everything went OK, you are ready to flash! Press the reset button on the bottom of the Planck, wait two seconds, then:
$ make dfu
. . . profit!!!
