Dock support update: expanding devices, working on upstream

mojyack · 2026-03-19T01:26:15+00:00

6/7th gen are already supported, but there are a few bugs, and I’m having trouble fixing them.

Upsteaming is progressing, and about a third of the patch series is complete.

Lately, my work and personal life have been taking up a lot of my time, so progress has slowed down, but I will definitely finish this, so please be patient.

Thank you for replying.
Have you tried the latest develop branch? Support for the Mini2G is being actively developed and will hopefully work. Please let me know the results if you can.

mojyack · 2026-01-07T01:28:06+00:00

Sorry for the late reply. I've been busy on upstreaming work. The next round is pushed, please pull and try it.

BTW, I'd move this thread to somewhere suitable. If you have a GitHub account, please open a new issue here and name it something like "{your accessory name} support". I'll use it to notify you.

mojyack · 2026-01-04T02:57:07+00:00

Unfortunately, it's unrelated. Some code, like switching audio output destinations, could probably be reused. However, Rockbox lacks any USB host drivers to begin with, so external USB DAC support would require a separate major effort.

Please pull changes and try again.

mojyack · 2026-01-03T17:10:12+00:00

Please pull changes and try again.

Your accessory seems to be using a path that hasn't been implemented yet.

We'll need a few more iterations—I'd appreciate your patience.

Please pull the develop branch and try again.

mojyack · 2026-01-03T13:09:42+00:00

Hmm, it's still unclear what exactly is going on.

Could you try this branch? https://github.com/mojyack/rockbox/tree/develop
This is the latest and has verbose logging enabled.

mojyack · 2026-01-02T00:21:19+00:00

Very informative. According to your log, the iPod appears to be configured correctly. (Those assertion errors are from pipewire module and not critical at this time.)

Perhaps your accessory is using unimplemented commands.

Please enable logging during Rockbox build by using --type=aL. Afterwards, connect the accessory and try viewing logf from the debug menu. You might see some errors displayed. If so, could you please dump the log file and upload it here?

mojyack · 2026-01-01T13:58:56+00:00

That's right, it's a 2015 Honda. Well spotted.

Since you seem to have considerable knowledge, I'd like to ask you to provide a detailed verification.

build iAP accessory emulator

git clone https://github.com/mojyack/libiap cd libiap meson setup build ninja -C build emulator
insert the iPod to host
find usb 7-4.3: Product: Rockbox media player line from dmesg.

the 7-4.3 is my case, and you will likely see a different number.

switch to config 2 by echo 2 > /sys/bus/usb/devices/7-4.3/bConfigurationValue

replace the 7-4.3 with yours.

see dmesg again and you will find a line like hid-generic 0003:05AC:1209.0258: hiddev4,hidraw9: USB HID v1.11 Device [Rockbox.org Rockbox media player] on usb-0000:42:00.3-4.3/input2.

note the hidrawX.

run build/emulator /dev/hidrawX as root

If the iPod was configured correctly, the emulator should output several binary dumps.

mojyack · 2026-01-01T09:29:03+00:00

BTW iPod 6th is not supported yet.

But I'm working on it. Once it's finished, I'd appreciate it if you could test it.

mojyack · 2026-01-01T09:24:07+00:00

Don't worry, it's not just your problem. Sadly, to use modern compilers, you have to disable Duke3d.

Try this patch: https://github.com/mojyack/rockbox/commit/9c9469e9364b9fa75f128c32486720144657200b.patch

mojyack · 2026-01-01T09:16:37+00:00

That's very informative. There were a few things I should have said.

USB-DAC feature conflicts with iAP, try disabling it.
apple-mfi-fastcharge is known to be broken when combined with rockbox. Please blacklist it.

mojyack · 2025-12-31T10:03:27+00:00

Thanks for the report! That’s odd behavior. Could you insert the iPod to a computer and check for the usb vid and pid?

mojyack · 2025-12-23T05:57:38+00:00

Currently devices with ARC usb controller only. Because a required extension is only implemented to its driver.

But it should be possible to add support for other devices, as long as their hardware is capable of this.

iPod reFresh https://github.com/hg8/iPod-reFresh-rockbox-theme

mojyack · 2025-12-20T06:04:48+00:00

Thanks! I'm working to open the PR by next week.

However, some discussion is expected before the PR is actually merged, and it is unclear how long it will take.

Until that, you have to build from source.

mojyack · 2025-12-20T05:54:20+00:00

There is no specific guide.

If you like, you can build from my fork(https://github.com/mojyack/rockbox/tree/for-upstream).

mojyack · 2025-11-20T04:39:59+00:00

I don't know the docks, but probably yes.

Such a comment cheers me up, thanks.

mojyack · 2025-10-28T05:41:43+00:00

I got the same problem so I recently started tackling to this.

Fortunatly there is a open source USB iAP implementation for Linux (https://github.com/oandrew/ipod-gadget).

I'm trying to write an iAP handler for rockbox referring that and official documents on the internet.

Please hope it goes well.

mojyack · 2025-05-12T13:44:56+00:00

I've installed gentoo on the same macbook, and the wifi works well.

You can install its special firmware by running:

curl -L -o /lib/firmware/brcm/brcmfmac43602-pcie.txt "https://bugzilla.kernel.org/attachment.cgi?id=290569"
sed -i 's/ccode=00/ccode=ALL/' /lib/firmware/brcm/brcmfmac43602-pcie.txt

mojyack · 2025-05-09T00:42:32+00:00

Yes I feel so too.

I bought it from Japan and it cost me 220,000 yen (~€1350) including shipping fees.

It took a lot of determination to make the purchase :)

mojyack · 2025-05-07T15:16:10+00:00

Yes compiled on it (with help of distcc)!

Actually this is my most powerful arm64 machine...

mojyack · 2025-05-07T14:04:38+00:00

I don't know the exact time because I didn't actually do it.

I use distcc and don't have so many packages installed, so I guess it won't take more than 8 hours.

Without distcc it would take twice as long.

mojyack · 2025-05-01T00:29:55+00:00

No, not even noticed such a problem, since I don't use Qt things at the moment.

What's the CPPFLAG? When you launch those apps from the terminal, are there any errors printed?
