New Ports / Re: AIGO EROS Q / AIGO EROS K / IRULU Surfans F20 / AGPTek H3 / HIFI WALKER H2
« Last post by coomer101 on Today at 12:46:29 AM »This family of devices is one of the few (if only) rockbox PMPs that are powerful enough to have several EQ filters while playing high res files.
I wonder if there's a way to have rockbox recognize AutoEQ configs?
I've been "translating" them by hand and it works very well, but it's very tedious.
Been brainstorming ways to at least have a bash script convert them PC side then moving them to the payer but my sed and awk skills just aren't there sadly.
Anyone else use the parametric EQ? Very underrated feature of rockbox imo

« Last post by Alan Tochterman on March 27, 2024, 08:20:16 PM »I was unable to find anything in the forums nor on Reddit.
Again, I have no clue how to make it operate. I assume it is something in the logic board itself. The 6th gens use the same earphone jack, as the Videos and the later units, but the feature is not on them. So I assume it had to be in the board itself.
Is this forum the proper one to make requests ?

Perhaps I was not using the proper terminology.
I am referring to the volume control on headphones, not from the 30-pin connector. iPods from the Video (5th generation) forward used a TRRS style headphone jack. On the Video the extra contact point was for composite video out. On the 6.5 and 7th generation iPods the extra contact point was for the volume control and microphone like on the iPhone 4S.
On my Apple earphones and on my Bose QC20s there is a small control unit on the wire to the right ear peace which controls volume and pause, and I believe track forward and reverse. When I am in Apple mode (which is almost never, these days) it works perfectly.
Once in Rockbox, it becomes non-functional.
If I am taking a walk and my iPod is in my pocket, it is nice to be able to adjust the volume without having to take the iPod out.

« Last post by Trzyzet on March 27, 2024, 04:32:05 PM »I've already started some basic PCB design. It will be similar to tenga from this thread - PCB with PMIC, buttons, charge/data USB port, socket for LCD and you just need to solder the ox64. I'm opting for a removable battery like Nokias BL-xx
When I finish the basics I will share kicad project on github. Maybe someone will have some time and will to improve it. Also, there is a few different BL808 based modules, I'm sure there will be something more like ESP32 size.
I was thinking about 3D printed cases. Even PLA will be looking factory-like when you will smooth it with acetone.
The only thing about SoC which hurts me really bad is lack of USB 3.0 support. USB 2.0 is so outdated these days it just hurts.

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.
