Title: Fiio M3k
Post by: chocovy on July 23, 2019, 04:04:46 AM
Gonna start a thread for the fiio m3k (not m3)

So far this is what I was able to gather on what's inside the player.

SoC: Ingenic X1000e
OS: Custom (linux-based)
DAC: AKM AK4376A
Power management IC: AXP192
Screen: 2.0 inch IPS TFT 240×320

Until I can figure out how I can disassemble the unit safely the pcb scans have to wait I guess...
Can't really help out on the software side of things as I'm only familiar with C++.

This is where the firmware updater (and other firmware versions of the player) is located
http://www.fiio.me/forum.php?mod=viewthread&tid=43627&extra=page=1

will update this thread on further findings

Here we go!
Rockbox for the FiiO M3K is available on my site:
http://xvtx.ru/rockbox/download.htm (http://xvtx.ru/rockbox/download.htm)

- Based on the stock FW v1.3.0 (which has also been optimized for speed and memory usage).
- It is flashed like a regular firmware (...and rolls back also).
- Almost everything works, but minor bugs will be fixed over time.

Enjoy!
(and please consider a donation for me or/and rb team if You'd like it).

P.S. source code will available later, when all settle a bit.

Awesome work! How does one go about installing this on the player? What bugs have you noticed?

You should install it as regular update: https://www.fiio.com/newsinfo/82055.html
There are several minor issues, they will be fixed in the next version. Nothing serious.

I got it installed and its working pretty great, gotta say i absolutely love rockbox. only 2 errors so far, both errors on bus (one said 10 i believe and the other 11), first one happened when i tried to open my library before scanning the database, the second happened when listening to music and going through the plugins menu. Hope this helps!

Edit: also just noticed there doesnt seem to be a way to lock the screen with the physical screen lock button

Depends on which theme. Cabbie has the lock feature. Hold on /off button for 3 seconds to lock or unlock. Updated version available now through link in Rockbox general discussion forum.

So I've used it for a few days now and here's the bugs I've encountered.

The worst is that I can no longer boot into the stock OS, it just freezes up after I select fiio music.
It also is completely off on the battery level, it'll be at 0 for a while but stay on, or say 30 then jump to 17 when I plug it in.
It also seems to have a problem keeping setting changes.
Also still experiencing crashes when loading large lists in file view.

Hi, thanks for the port - good job.
I found one bug, however.  The left-right balance does not work for me. Volume in both headphones is turned down instead of just one side.
I would also like to ask if it is possible to make the volume control work even when the keys are locked.
Thanks for the reply.

If the device has a physical lock button we don't put code for the soft lock stuff which allows keys to be pressed while locked
However it is possible to add it http://forums.rockbox.org/index.php/topic,52539.0.html

Just letting you know that the most recent version of Rockbox on your site for the M3K is basically unusable, as it doesn’t let you change the volume and instead defaults to just very very loud. Just letting you know.
