Fiio M3k

[Richie325]

I have been using rockbox on this device for over 2 weeks now. I noticed that the voice in the right earphone is a bit distorted and the left earphone is clear(If you change the balance and listen to only one side you will notice it). I tried different headphones and earphones as well. This issue is not present when i boot to the stock OS.

I've updated the kernel on my github for anyone interested.
https://github.com/froggestspirit/FiiO_M3K_Kernel/releases/tag/v1.01
As I mentioned, I don't know if I'll be working too much more on the kernel itself, but the code is there if anyone wants to pick it up.

I've tried many different files and listened very carefully as you suggest but I can't hear any distortion on my Rockboxed M3K.

In this post https://forums.rockbox.org/index.php/topic,52917.msg246172.html#msg246172 efqw explained that "The main player application is aggressively logging to /data/userfs/app.log. I'm really concerned about this wearing out my NAND", is that fixed in that new version of the kernel?

It's not kernel issue, it's stock player application issue. It relates to firmware (rootfs image) modifications but not to kernel or rockbox.

I followed alexs's instructions and installed the newest version. The bug of not being able to scroll up on the search input is still the same.

The problem is only being able to move down, left and right, so that if you miss your letter you have to scroll all the way around to it in order to pick it again. Is there any fix to this? Thanks

Wow, Ok! I should have listened to the warnings in this thread! Gonna post my experience here so others know not to install this version yet.

I have been using the Vortex version for a few weeks and it works great except for some minor bugs like scrubbing through songs and not being able to scroll up while typing text. I wanted to see how the development was going so I followed this thread and installed the latest version of RockBox, that was a mistake!

The current version has a fix for the scrubbing issue, but the search issue is still there, and is honestly worse because now the letters are all on one page and very tiny.

But most of all, this version auto logs you into Rockbox without any option of going to the Fiio version, and the ability to access the device from a computer is totally broken. I don't have an SD card reader so this means I have literally no way to add new music, get to the USB DAC or fix this in any way until I get a reader. I can't go back to the other version because I can't remove the Rockbox files from the SD because file access is broken.

Thanks everyone for working on this, definitely my fault for installing unfinished software, but to people wondering if they should install this, don't do it yet! For now, the Vortex version is in a much better state as it actually lets you go back to the official firmware without an SD card reader. Good luck everyone!

There's a reason it's listed as "unusable" on the main rockbox web page.

(Or more accurately, _many_ reasons...)

At least it motivated me to try compiling this myself. Gonna see if I can fix up the search menu bug and reorganize the letters in a better way, seeing as the search isn't case sensitive so I really only need one set of the letters.

So far I've changed the calculator labels to say "D I D  T H I S  W O R K" so I have a long way to go lol

Hey!

I solved the bug of not being able to scroll up in text entry on the Fiio M3K! Someone literally just forgot to add the code to enable "ACTION_KBD_UP".

The problem was totally fixed for me if I add this line:

Code: [Select]

    { ACTION_KBD_UP,          BUTTON_UP,                        BUTTON_NONE },
    { ACTION_KBD_UP,          BUTTON_UP|BUTTON_REPEAT,          BUTTON_NONE },

Before line 100 in the file apps/keymaps/keymap-fiiom3klinux.c

Can someone check my work? I'm not set up to submit code yet, this is my first time ever working on an open source project. Let me know if this looks good and also fixes it for other people!

[speachy]

That looks good!

If you'd like to take this all the way thorough and submit a patch, you can do that via the bug tracker or through gerrit directly (see https://www.rockbox.org/wiki/UsingGit for how to set it up)  Otherwise I'll be happy to do it for you.

(We will need your legal name to accept a patch, FYI)

[heyspencerb]

Awesome! If possible I'd love to submit it! It would be my first accepted code.

I followed the guide for submitting and added my ssh key but when I ran the test I got this error:

Permission denied (publickey)

[heyspencerb]

Fixed the issue! Just submitted for review, thanks!

Here is the link to the change if you'd be willing to review it!

Hi, can I flash the 1.4.3 firmware if I'm running 1.4.5? That means can I downgrade?
