Rockbox Player - Project to design and build a Free/Open hardware audio player
LADave:
Embedded Linux ( https://www.yoctoproject.org/ ) is an alternative to replacing a cellphone's native O/S with Rockbox. Then a RB port would have to be done, hopefully only once for all devices running this flavor of Linux. Thanks to BenBrown for clueing me in! Unfortunately Embedded Linux is still a work in progress.

One of the points of Lyre was to have truly open software, and hardware.
Something anyone with the source code and schematics could whip up on their own home desktop and fabrication table.
Using cellular phones defeats that entirely.
Now, before anyone rushes to say "But Android is open!", it isn't.
Period.
There is a project by the name of Replicant that aims to replace closed vendor binaries with open alternatives, but the outlook for this project is truly bleak. Off the top of my head there isn't a single device that isn't functionally crippled in some massive way.
But the main thing is the hardware. Using phones, the project cannot evolve as freely as a project like this should.

The limitation isn't software nor hardware (effectively manufactured PCB) which throttles these efforts but ironically competent fabrication of the physical enclosure to the extent it is something you'd want to carry around. So from that narrow perspective I can see the motivation to leverage existing cell phone product. But doing so addresses only this single consideration and otherwise you're pounding a round peg into a square hole from a design suitability perspective. Add to that there is no control of the repurposed product availability and the leveraged effort can be derailed at any time, and moreover will be derailed at some time, likely without notice.

It is difficult to believe it has been 5 years since I'd designed this. And it certainly could use some updating at this point.
The links earlier in this thread are obsolete so I've located the information here:

If someone is interested to move this project ahead feel free to PM me in this forum.

Would it be possible to release CAD/CAM and BOM as well?

Hi all,
I signed up in the forum because I want to contribute on this topic. These days you can get STM32 ARM CortexM for very low money, do any of them fullfills the RB min REQ?:

You could output the data through I2S to a decent DAC, then to a headphone output. I think the only we would be missing is native USB support for data transfer and charging.
Thanks
