FiiO M3K Install (Native port)

[juupi]

It's 2 keys combination in rockbox: Play + Vol Up and Play + Vol Down

Thanks, but that doesn't work on my device. Do I have to enable it anywhere?

It should work when device is locked.  Also make sure you have
Settings -> General Settings -> System -> Advanced key lock

Enabled - Yes
And Exempt Seek, Exempt Skip and  Disable Touch should be enabled (other options can also be enabled, it's just minimal set to make skip and seek work by Play + Volume keys combination)

Here I can't do / change anything. Additional confusing: the names depends to language settings:
English:

• Exempt Volume
  Exempt Play
  Exempt Seek
  ....

German

• Exempt Volume
  Play
  Seek
  ....

When device is locked only volume control is possible (as german settings)

*PANIC*
TLB refill handler at 0x8007f14c! [0x0]

Just wanted to call out for folks receiving errors like these from the firmware and who have SD cards larger than 32GB:

• Panic TLB Refill Handler
• Error -2
• Rockbox File Not Found
• etc.

Double-check that your SD card is still FAT32, not exFAT. I broke my original install somehow, formatted the drive (exFAT), and got each of the above errors depending on the action I was trying to take (boot, restore firmware backups, etc.). Smelled like filesystem errors so I checked for a dying card, but a full read/write scan reported OK.

FAT32 is the answer, as vitt13 mentioned above. Easiest way to get back to it is to boot the M3K into the stock OS (hold play before/while powering on) and format it from Settings there. No need to fight with your PC to allow you to format a large drive FAT32.

Copy .rockbox back over (even while booted into the stock OS) and you should be fine from there.

projeKct and dconrad would either of you be able to test a new bootloader on your M3Ks? I fixed a couple of bugs yesterday and I think it might fix the recovery kernel hang on your units. If you can also confirm the new bootloader still works to boot Rockbox and the Fiio player, I'll put this up as the next 'official' release.

The new bootloader is here (FYI this corresponds to the series g#4348):

You can install it from the rockbox bootloader menu or by jztool, just be prepared to re-install the old bootloader using jztool in case the new one is broken.

Amachronic, just flashed that bootloader build onto my m3k, which has not seen a new build of either bootloader or rockbox in quite some time. I flashed it via the existing bootloader and it seemed to work without any issue. I have build dbb7371065-211128 (!!) on my player - you can see I don't use it much at the moment, lol. It also boots fine with build b309fae2bc-220317, the latest and greatest.

Booting RB works, booting OF works, getting into the bootloader menu works, USB mode appears to work fine, bootloader area backup appears to work fine.

Any other tests you would like me to do?

[amachronic]

Did it boot the OF recovery as well? (I recall it didn't work on your unit with the old bootloader)

[dconrad]

Ah, I didn't try that one. I do get "uImage load failed" trying to launch Fiio recovery. I assume it doesn't need the recovery image actually on the SD card, right?

[amachronic]

The error is referring to the flashed recovery kernel uimage, so I guess it's corrupted or maybe an unsupported option. I'll put together a new build this weekend so we can figure out what's going wrong.

[amachronic]

Here is that build:

dconrad can you please try loading the fiio recovery with that and tell me the error code it gives? I'll need you to post the recovery kernel image too, which can now be dumped via the debug tools menu. Thanks!

This is the recovery kernel I dumped from my unit (for comparison):

While waiting for dconrad's feedback, I'd like to report that the 220319 bootloader works fine. When loading the FIIO recovery there is no error, it only displays "No Update File". I had FW v1.4.5 before and my recovery kernel image has identical hash as amachronic's.

I am new to Rockbox so please excuse my ignorance but I can not get bookmarks to work. I selected:

• update on stop: yes
• maintain a list of recent bookmarks: one per track

"Bookmarking only works when tracks are launched from the file browser, and does not work for tracks launched via the database. In addition, they do not work with dynamic playlists."

I do not use playlists, in file browser mode I start/stop audiobook files but no bookmark is registered. Why?

[dconrad]

After a change to ignore bad nand blocks, the bootloader is fully functional on my player.

AACC, with those bookmark settings you'll need to go into the context menu of the While Playing screen and manually create a bookmark, then it should update the bookmark for that playlist whenever playback is stopped after that. If you want it to always make bookmarks for any file, you can use "Bookmark on Stop" set to either Yes or Ask.

The way you've got it set up, it will update bookmarks after you manually create them once, but it will not create them where they don't already exist.

The way rockbox works, you always have a playlist even when you just play a particular file. I think by default this "dynamic" playlist includes all files in the same folder.

I hope all that makes sense.

[AACC]

In WPS context menu there is nothing about bookmarks, I only see 'shuffle' and 'repeat' options. I did change "Bookmark on Stop" to Ask but there is no asking when I stop. Perhaps the rockbox-fiiom3k-20220318 version is buggy?

[dconrad]

If you only see shuffle and repeat, are you sure you're getting into the context menu? It sounds like you're in the quickscreen, which is accessed by pressing the top left button (menu, I guess I would call it?). The context menu is accessed by a long press on the scroll strip. The Bookmarks entry should be between Playback Settings and Open Plugin.

If it's not between those two entries, that means that the dynamic playlist I mentioned earlier has been modified and it needs to be saved, but it sounds like that's not the problem you're running into.

I'm pretty sure the Ask option for Bookmark on Stop works fine, I just tested it on my player with a build just one day older than yours. Just to be sure, are you sure you're actually stopping playback? You need to hold the power button for about a second or so, but not long enough to power off the device. It should ask you to save or not then.

[AACC]

dconrad you are right on all points, thank you for your explanation. Bookmarks are essential for my audiobook collection and Rockbox truly ROCKS. I am installing it on my spare M3K too and never going back to original firmware. Oh wait, not sure about battery performance yet, just started using it. What are your observations about battery life?
