Rockbox Player - Project to design and build a Free/Open hardware audio player

Ok, I found another thread about porting RB to a Cortex M4 or even a M7:

THis dates from a year ago. Has any work being done at all here? I could quickly do some quick PCBa design around it.

I don't think so. I don't even recall seeing anyone use Cortex M processors for a portable audio player yet.

saratoga: There was a guy which claimed to have preliminary rb port for some M3 eval board. From the technical point of view there is no problem other then time and persistance really.

Unless you were planning on carrying a bare PCB around or the same
stuffed into a clunky enclosure, fabing a PCB really isn't the problem.
Rather it is the mechanical design of the device which torpedoes these
efforts.
I suppose if you could accept a 3D printed enclosure that may be a partial
solution. But given the effective resolution of even commercial printers
it isn't something I'd want to brag about. For small quantity runs it might be
feasible to CNC machine enclosures using a well fixtured blank. You'll
still need to address surface finish quality but would be in a far better
starting point relative to printing. Still you'd never reach the level of quality
achieved with large scale injection molded components from insanely
expensive dies.
This is assuming you have a design ready to manufacture. Getting there is
no mean feat with interdependent tradeoffs between display technology and
available footprints; battery technology, footprint, runtime, interconnect, etc..
No doubt you could amass the engineering talent needed to get the job done
particularly in the context of a collaborative, open effort. But successfully
executing the manufacturing task is usually where such projects fizzle out.

I agree with the comments about the case and real portability of such a product. We are not talking about an O2 DIY that will sit next to your PC and doesnt need to be taken out.
However, if someone could direct me to however did a port to the M4, please let me know, I would be really interested in give it a go.
Thanks
