Unofficial Behringer Control Development Kit
--------------------------------------------
The Behringer Control series are general purpose MIDI controllers. The firmware
of these devices can be updated by sending special midi messages. This package
contains the tools generate these midi messages from a firmware image and vice
versa, and to upload them.
For building custom software for this device, please see README.firmware.
Requires Python.
--- IMPORTANT NOTE ----
This software is unofficial and based on reverse engineering efforts. Although
unlikely, reprogramming your device may actually render it dysfunctional and
unrecoverable without physically opening it and reprogramming the flash chip by
other means (bricked). Care has been taken to prevent this, but is not
impossible. You have been warned.
This development kit was created to promote interoperability of BC2000 devices,
and to allow fixing errors by the community. It is not allowed to use this for
creating commercial clones of these devices.
--- IMPORTANT NOTE ----
** bcfwconvert.py
Converts between the various file formats. The formats are:
- syx: System exclusive midi messages that program the device. The official
firmware from Behringer is in this format.
- dump: Memory dump that corresponds to the device's internal flash memory.
- os: An operating system image, that is the compiled code. This is
different from a memory dump in that the memory dump contains an
obfuscated os image, preceeded by a length and a checksum.
The most commonly used formats will be syx and os, the former to upload a
program to the device and the latter as the binary output of the linker.
** bcfwflash.py
Uploads a midi firmware image to the device and displays feedback on its
progress. By default it scans each midi device for an attached Behringer
Control device and connects to the first found.
This utility has only been tested on Linux and will probably not work on
non-unix-like systems as it needs a device file to read and write from.
** Examples
Convert an existing midi firmware file to an operating system image
$ bcfwconvert -i bcf2000_1-07.syx -I syx -o bcf2000_1-07.bin -O os
Compile an assembly program and generate a sysex file to program the device
$ arm-as -o test.elf test.S
$ arm-objcopy -O binary test.elf test.bin
$ bcfwconvert -i test.bin -I os -o test.syx -O syx
Detect attached Behringer Control devices (BCF2000 attached via USB)
$ bcfwflash -l
/dev/snd/midiC1D0: BCF2000 1.10
Upload a midi firmware file to the first detected device
$ bcfwflash -u -i bcf2000_1-07.syx
Flash an operating system image directly to the specified midi port
$ bcfwconvert -i test.bin -I os -O syx | bcfwflash -u -d /dev/midi0
Display the string "ABBA" on the device's display
$ bcfwflash -p ABBA
