Hello, The "panic: Attempted to execute unimplemented instruction 'mrc'" message means that your code is trying to access a coprocessor. You have to check if your code can run in the FS mode.
To run your own OS, the 'baremetal' option may be interesting in the FS mode, but I've never tried. Hope it helps, -- Fernando A.
