Hardware / Re: New cheap portable player in the market
« Last post by Bilgus on August 03, 2022, 06:52:47 AM »Unfortunately I think without having a upgrade file for the firmware or at the very least some idea of the internal chip and its layout
we are never going to be able to do anything with this player
I was hoping there was jtag on the device that might allow some probing but it appears everything is done with the USB to me
maybe some deal with the chinese manufacturer and a SDK but where to start without knowing who that is IDK

« Last post by Bilgus on August 03, 2022, 12:00:08 AM »First day with these devices and I already had one stop enumerating as USB and now won't even turn on that was before I started messing with getting into boot mode 
taking it apart it has the same QA 2100 but with 2022ad005c
the back side of the board is marked j01 wb vl1 210315
The second one I have managed to brick and disconnecting power / reconnecting brought it back luckily
also no need to use the reset button simply turn player off (long press play/pause) then hold M while plugging USB
i then enumerates as 4d00

« Last post by dconrad on August 02, 2022, 05:20:20 PM »Sorry, that definitely could be clearer. My understanding is that yes, the line out functionality is the only thing on the 2.7 firmware units that doesn't work.

Hardware / Surfans F20 w/ v2.7 firmware: Clarification on state of support?
« Last post by Abscissa on August 02, 2022, 03:45:24 PM »On this page: https://www.rockbox.org/wiki/AIGOErosQK
It says "newer Surfans F20 units which ship with firmware 2.7 appear to have audio hardware changes, and line out functionality does not work in Rockbox yet on these specific units."
So obviously, if I get that version of the device, I can't expect the line-out to work right now, but I'm unclear on one detail:
In comparison to the other AIGO EROS Q/K devices: Is that statement saying that there are ALSO OTHER things besides the line-out that aren't working yet? Or is it just simply saying that line-out not working IS the one and only limitation currently caused by these audio hardware changes?

Rockbox General Discussion / Re: I'd like to buy a new player to put rockbox on, what should I look at?
« Last post by Oscar on August 01, 2022, 03:17:00 PM »I do own a Shanling Q1 as well as a Surfans F20 (since a few days). Both run Rockbox quite well. I'm happy with both of them. Both do have a more than reasonable battery runtime with my typically 320 kbps MP3 music library. The Shanling runs in my test for about 19 hours and the Surfans F20 runs even for 26 hours non stop playing. To answer one of your questions: I use a 512 GB microSD card on both devices without any problem.
Since my Surfans F20 is the one with the v2.7 firmware and the "new" NAND, I had to use the bootloader (v7) from the thread https://forums.rockbox.org/index.php/topic,54228.0.html to install the native port. It went without any problems.
I slightly prefer the Shanling Q1 over the Surfans F20 though. These are the reasons:
I can't say anything about the Fiio M3K, except that it is hardly available anymore as well.

I slightly prefer the Shanling Q1 over the Surfans F20 though. These are the reasons:
- The Q1 has the bigger and better looking screen
- The Q1 has a touch screen. And with adequate settings/themes Rockbox runs reasonably well with a touch screen.
- The housing of the Q1 is rounder and works better in my hands and my pockets. I don't like the sharp edges of the F20. Maybe the Hifi Walker is better in this regard?

Other - Installation/Removal / Re: Surfans F20 "NAND open error"
« Last post by twotoneblue on August 01, 2022, 03:11:49 PM »kaas, twotoneblue - could either of you provide another dump with the v7 bootloader to ensure it still works with the Winbond flash? I made a couple tweaks, which shouldn't have broken anything but it's a good idea to test again just in case. Thanks.
Dear all,
Apologies for not seeing the updates here - for some reason the notification didn't reach me. Here is the usual package with the v7 bootloader: https://drive.google.com/file/d/15Tw912xBi0yB0LDxorQVqi4igAxwtAQg/view?usp=sharing
There are a few differences - I believe you can make more sense of them than me.
Thanks for your continued investigations, everyone!

New Ports / Re: Rockbox Player - Project to design and build a Free/Open hardware audio player
« Last post by RandomInsano on July 31, 2022, 01:53:52 AM »Exhuming this thread. I won't make any promises, but if I made five Raspberry Pi based daughterboards would there be devs willing to port Rockbox to the BCM2835 that's in the Raspberry Pi Zero? I built a prototype tonight and am streaming music on it in Linux now. The Pis will be hard to get...
https://imgur.com/a/svWt4Dq
I bought some cheap junk off the Internet (PCM5102 I2S DAC, SSD1306 OLED module) that are widely used by Raspberry Pi and Arduino users and I think is what's in the Hackaday article. With some light electrical engineering it's possible to make something smaller than the volume of an iPod classic. I don't expect it can be done for less than $50 USD because people's time costs more than the bill of materials but I paid ~$40 CAD just buying off Amazon (already had the Pi)
The *real* question I think is does anyone want to try and port Rockbox natively to the Pi? There are bare-metal toolchains now (I use a different Pi to emulate a Commodore 1641 disk drive https://cbm-pi1541.firebaseapp.com/) and it's well documented. If there's interest I may just build a few with these parts and send them out. I would only send to active port maintainers though.
I'll float the hardware side of this idea past some friends to see if they'd want to tackle that side of it, but as it stands I built mine in an hour and didn't need a daughterboard.

* https://www.digikey.ca/en/products/detail/midas-displays/MCOT128032CY-WS/15854837 (~$11 in orders of 100)
If there are better options for screen and DAC I'm open to suggestions but I want them to already be in use with the Pi and have their source documented.
No promises at all, but I think this could be fun.
Back the next day with some adventures. This device from Pimaroni is about 66% of the way there (need a battery) to give an idea of how small it could actually be:

Rockbox General Discussion / Re: I'd like to buy a new player to put rockbox on, what should I look at?
« Last post by Ren on July 30, 2022, 10:01:15 PM »I'm also looking to buy a new DAP for ROCKbox.
This would be my first ROCKbox player so far. I only found out about the existence of this alternative open source firmware about a month ago or so.
But I have many years and lots of experiences with modding gaming consoles, or flashing firmwares like LineageOS etc. onto Android devices.
From looking through many of the listed Players in the Target List and in price comparison sites/ebay/amazon... I came up with 3 possible choices that would be possible to buy from within germany. And seem to have a somewhat good stability of ROCKbox. The Shanling Q1, The Fiio M3K, and the Surfans F20. From what I've seen the Surfans F20 looks best to me. But maybe you can tell me your thoughts on this matter?
Also what isn't clar to me is if it would be possible to use bigger microsdxc cards than 256GB in the Surfans F20, since I read that would be the limit. But it seems artificial to me why there should be a size limit like this when bigger microsdxc cards have the same technical standart...? Has anyone tried to use bigger cards in this player? And what about changing the battery of this player, are there spare ones available? I couldn't find any...
