Taking the hosted port approach would be the path of least resistance, and there's enough RAM to still have plenty of resources for Rockbox. But while that Pine64 board might make for the basis of an early prototype on a breadboard, the real hurdle is the physical enclosure. That dictates the design of the PCB and the other major components (screen, battery, etc)
...the tooling to make the case can be pretty expensive (and paid up-front), but you amortize it over your production run, so the more you make, the lower the overall per-unit cost. But the larger your production run, the more money you need up-front to pay for components. Economies of scale on component pricing don't really kick in until you're looking at 1000-10000 units.
...If we had some folks that speak one of the common Chinese languages, we might be able to negotiate with an existing OEM to produce us a palette-load of an existing player design, contingent on supplying complete board schematics and all relevant source code. Or even just purchase a pile of empty cases for us to design our own PCB into.
I wonder if it's feasible to design a new PCB to go into a classic iPod enclosure. Actually it would probably be cheaper to buy a pile of those shovelware atj2127-based players, throw the PCBs out, and put a new PCB in there instead...

Apple - Installation/Removal / RockBox on iPod Classic 120Gb
« Last post by LightHorse98 on March 27, 2024, 02:51:12 PM »Hi people of RB-forum,
Recently I've installed RockBox through UMS-boot by Emcore. This action cause the iPod couldn't be reset by Apple iTunes. So now I use the Emcore bootscreen and choose the RockBox button at the boot to play music. The iPod Classic is formatted to FAT32 with clustersize 32kb in one partition of 111,8Gb. On the root directory there is the ".rockbox" folder and the created "music" folder I made for the Albums. I've copied some Albums through "Teracopy" with Windows 7 on my laptop. When I deattach the iPod from my laptop it goes well. Then I turn on the iPod and scan the database. I can find the Albums, but now I got a real problem cause the first song I play got played well but the next song won't be played... Sometimes I tried a different song after rebooting and the different song will also be played. But the next song won't. Is there an option I've missed out!?

I started to think about that kind of project, a Rockbox dedicated, open source player and I found something which could be a very nice start.
https://www.cnx-software.com/2022/12/02/pine64-ox64-sbc-bl808-risc-v-multi-protocol-wisoc-64mb-ram/
Nice CPU, plenty of RAM, I2S support, low power draw and a lot of modern things like bluetooth and wifi.
With some effort it can be a fully featured DAP similar to a Surfans F20 and others with same CPU.
MIPI sounds like a nice, 3.5 inch 640x480 screen, with I2S there can be support for HiRes.
The problem might be a CPU architecture but there should be a linux for this board and for Linux, we can run something like a hosted port.

Hardware / Re: Native Port Hifi Walker H2 playback judder/skipping
« Last post by Elm1825 on March 27, 2024, 10:03:44 AM »It acted up again this morning. Restarted the track a handful of times before it played right. Track played fine several times yesterday. Not sure. This was the first track after it booted. The player was off all night. It resumed playback right away. I restarted the track and after a few seconds it started cutting out.

Hardware / iPod Classic 6.5gen and 7gen In-Line Volume control
« Last post by Alan Tochterman on March 27, 2024, 12:12:53 AM »Hello:
I am hoping that this is the correct forum to post my request.
The iPod Classic 120gb (6.5gen) and 160gb thin (7gen) were the only two models to support in-line volume control amongst a few others, for Apple or Apple approved earphones/headphones.
The feature works with Apple's native operating system, but not on Rockbox.
Since I am not a programmer, I have no idea how difficult it would be to enable this feature on these two devices. But if it is possible, I would like to make the request.
Thank you

Hardware / Re: iFlash Solo – perfectly reliable iPod/sd-card combos
« Last post by chris_s on March 26, 2024, 08:12:43 PM »Fwiw, the info from the OP is outdated as there've been further changes since then. The current dev build, at least in my experience should now work as-is both on an iPod video and iPod 4g (monochrome) when combined with an iFlash solo, possibly depending on the SD card used... Not sure about the iPod color though.
There's a somewhat more recent iFlash compatibility discussion going on here: https://forums.rockbox.org/index.php/topic,52560.msg253273.html

I should try turning DMA back on...
