The OSP is a hackable, open source drum machine that accidentally got very, very close to the erica perkons hd-01, which is real beauty of instrument design that i truly love, except for its unhackable closed source nature. So, we new need gnu one.

The OSP is a hackable, open source drum machine that accidentally got very, very close to the erica perkons hd-01,
which is a real beauty of instrument design that i truly love, except for its unhackable closed source nature.
So, i made a gnu one.

Build Instructions

Toolchain Setup

Compiler

compiler used is gcc for arm:
Options:

install version specified by electro-smith: https://developer.arm.com/downloads/-/gnu-rm
install the latest version: https://developer.arm.com/Tools%20and%20Software/GNU%20Toolchain

IMPORTANT: Do NOT use any OTHER gcc-arm toolchain than these ones!!! There is a pitfall that is quite hard to debug. I used the gcc-arm from macports. There is NO libc-nano shipped with it, because its not GPL. BUT the daisy build scripts specify the use of libc-nano.

Programmer / Debugger

on macos: port install dfu-util openocd

dfu-util is the program that is invoked by the Makefiles to program the thing via DFU. openocd is the program that is invoked by the Makefiles to program the thing via JTAG. openocd also is the debugger we use.
