    Hey there! I’m in desperate need of help, since my Owl Pedal is totally bricked.

    I’m trying to update the bootloader using the following guide (,
    which then led me to the git repo with another guide on how to build it (

    I downloaded make, duf-util and the GNU ARM toolchain. After some troubleshooting i found out that the folder that the toolchain was in was named incorrectly. After fixing this, i went through a series of errors each time i tried to run “make”, where it said that “Tools” was not recognized as a command, and spitting out all the different .o-files. However, after running make a number of times, the console spits out another error(which i presume means that there was something weird going on with the .o-files, but that might(?) be fixed).

    The new error says:

    using ::abs;
    make: *** [Build/Owl.o] Error 1

    A google search didn’t give me any answers, or at least not any that i understood properly.

    I’m hoping that someone can help me, since i feel pretty damn stuck with this process at the moment.


    Mathias 🙂
