THIS IS A PRUSA3D BRANCH, WORKING AROUND A SPECIFIC PROBLEM
|
|
IN THE EARLY I3 MK2 USB COMMUNICATION CHIPS.
|
|
|
|
Some of the early Prusa3D i3 MK2 printers were shipped with a buggy
|
|
USB communication controller firmware. This fork of avrdude contains
|
|
a workaround inside the stk500v2 protocol implementation.
|
|
|
|
The workaround depends on a specific behavior of the Arduino AVR 2560
|
|
bootloader, which is installed on the i3 MK2 printers:
|
|
|
|
https://github.com/arduino/Arduino-stk500v2-bootloader
|
|
|
|
The avrdude binary modified by Prusa3D could replace the avrdude bianary
|
|
of arduino to program the RAMBo board. In that case the modified binary
|
|
is identified by a "-prusa3d" suffix to the version information.
|
|

|
See the documentation file for the details.
|
|
|

The latest version of AVRDUDE is always available here:

|
Important environment variables for ./configure:
|
|
================================================
|
|
|
|
CPPFLAGS: C preprocessor flags (*not* "C++")
|
|
|
|
This is the place to put additional (non-standard) -I options into.
|
|
For example, if your Windows system has LibUSB-Win32 installed into
|
|
\\WINDOWS\ProgramFiles\LibUSB-Win32, use
|
|
|
|
CPPFLAGS=-I/WINDOWS/ProgramFiles/LibUSB-Win32/include
|
|
|
|
to tell configure where to search for the header files. (The use of
|
|
forward slashes rather than backslashes can often simplify things.
|
|
Note that the Windows system services internally treat both the same.
|
|
It's only cmd.exe which requires backslashes as the directory
|
|
separator.)
|
|
|
|
LDFLAGS: Linker options
|
|
|
|
This is the place to make additional library locations known to the
|
|
linker. To continue the above example, use
|
|
|
|
LDFLAGS=-L/WINDOWS/ProgramFiles/LibUSB-Win32/lib/gcc
|
|
|
|
to make the linker search for "libusb.a" in that directory.
|
|
|
|
|
|
Linux users: make sure the header files are installed
|
|
=====================================================
|
|
|
|
While many Linux distributions install the libraries needed by AVRDUDE
|
|
(libusb, libelf) by default, they leave out the corresponding header
|
|
files. Consequently, the configure script won't find them, so these
|
|
libraries could not be used.
|
|
|
|
Usually, the packages with the header files (and static libraries) are
|
|
derived from the regular package name by appending "-devel". Thus,
|
|
make sure you have "libusb-devel" and "libelf-devel" installed before
|
|
running the configure script. (Same goes for libftdi.)
