Other - Installation/Removal / Re: Surfans F20 "NAND open error"
« Last post by GraFfiX on April 09, 2024, 12:59:20 AM »I bought a Surfans F20 Player as well and I want to install the native port on it.
[...]
Is it save to proceed with the installation of the native port with the latest (v7) bootloader from this thread?
[...]
Flash info:
readID opcode = FF C8 D1 C8
readID address = C8 D1 C8 D1
readID dummy = D1 C8 D1 C8
[...]
This shows you have the GigaDevice flash (same as JosephM's) so yes it's safe to install with the v7 bootloader.QuoteI installed the ROCKbox native port from the v7 bootloader, after a success message I first booted into ROCKbox from the BOOT Menue, this worked.
Then I rebooted and I just got a flickering screen.
So I powered the device off by long pressing power.
A new press on power just gives me the flickering screen again...
So I loaded the v7 bootloader from command promt again...
I reinstalled ROCKbox and powered off after.
I pressed power again and all I got is a flickering screen again.
So I started the bootloader again and created a Flashdump and the info files again.
here are they https://mega.nz/file/jTQS1K6Y#2OMx0mlbN7KqH24NBsz7AEeZqBCtWyXwTirj_9ecDxM
Then I restored the original bootloader. Now the player is working again with its original Firmware (not with ROCKbox sadly). I hope you will have success in getting the thing working with ROCKbox! If you need something else from me I try to provide it to you.
I don't know what the issue is, but if you try a few things it might help narrow things down:Also if you could explain what you mean by the screen "flickering" that would help. Can you see the Rockbox logo or menus? Do they look corrupted? Or do you see randomly colored "noise"? Better yet, post a video of the problem if you can. It doesn't have to be great, as long as the problem is visible.
- Go into the bootloader menu (hold volume up when powering on) and boot Rockbox - see if the LCD flickers
- Boot the original firmware from the bootloader menu - check if the LCD works
- Boot the original firmware by holding PLAY when powering on
Greetings, I recently acquired one of these players, and I'm having trouble getting the bootloader flashed on the device. I can boot the bootloader, but the image on the screen is flipped and inverted?
These are the parameters:
Code: [Select]
readID opcode = FF EF AA 21
readID address = EF AA 21 00
readID dummy = EF AA 21 00
sfc params0 = 06 05 04 03
sfc params1 = 02 55 AA 55
sfc params2 = 00 61 02 02
sfc params3 = B4 2F 00 00
Any clue what changes I could make to get the screen to present properly, and get the bootloader to install to my device? I can provide any further info you need. Thanks.

Hardware / Re: iFlash Solo – perfectly reliable iPod/sd-card combos
« Last post by Porklife on April 08, 2024, 01:29:50 PM »It's been a few years since I messed around with Rockbox, but I always remember it being "Rock" solid.
Seems it's quite broken now. I do appreciate its free / open-source and devs give their time freely etc, so not a criticism, just an observation.
My experience:
Ipod Classic 5.5G with iFlash quad and quality micros sd. Rockbox USB disk mode is borked. I've tried stable/daily/dev, all fail in the worst way, copy files from PC to ipod with no error message but files are corrupted on the ipod disk leading to track play weirdness
Ipod Classic 3G with iFlash CF adapter. Rockbox freezes, panics, reboots. Again stable, daily, dev builds. It's completely unusable.
Sansa e200v2 Rockbox USB disk mode borked. Copy starts but then goes slow and then fails with write error.
However on all 3 players above the stock OEM firmware performs flawlessly (albeit with the stock limitations). So suggests the hardware is not fundamentally the issue.
It would certainly be useful to have some documentation on what hardware mods and build version combinations are stable. Maybe I've just been unlucky, but 3 out of 3 fails seems like some fundamental usb/disk issues going on in the code.
Wish I had the dev skills to help out...all I can give is karma and respect...

https://www.mediafire.com/file/d8lw7bzhrl6xmw7/mRobe500_rockbox_NO_LCD_DMA.zip/file
also if you would can you make note of exactly how it fails and let me know if that changes when you run a build
like does it take longer flash the screen first etc.

Other - Installation/Removal / HiFi Walker H2 v1.5 Rockbox "incomplete installation"
« Last post by multiwirth on April 07, 2024, 01:06:36 PM »Hey there,
i've recently got my hands on a HiFi Walker H2 which seems to be the latest hardware revision.
It's stock firmware is 1.5 and it has the USB-C port aswell.
I just downloaded and installed the pre-patched 1.5 firmware image, after i failed to install the native port, as it would result with the error "can't open NAND".
So for now, i'm running the hosted build and that's probably good enough.
However, after placing the rockbox firmware to the root of the microSD card, it doesn´t seem to recognize it.
It boots from the nand flash instead and reports "incomplete install" with a very minimalistic interface.
If i go to the file explorer, i can very well see the microSD card beeing mounted, after digging through a very familiar linux filestructure.
So by navigating to mnt/sd_0/ there indeed is the .rockbox folder, containing all neccessary files on my card.
So why wouldn't it load the rockbox firmware from the microSD card?
I made sure to reformat the card using fat32, still not recognized, unfortunately.
Am i'm missing out on something?
Perhabs the mountpoint changed for some reason?
btw. i've dumped nand info aswell, in case anyone curious.

New Ports / Re: [Port Idea] Tangara The music player you wish you had in the early 2000s
« Last post by speachy on April 06, 2024, 05:43:58 PM »Yeah, but I mean, it's intended to be a music player. Why were music players from the 00s so overpowered then?
Most DAPs from 20 years ago used SoCs capable of running real operating systems. They were also relatively expensive, even before inflation is factored in.
Most stuff today is built around cheap microcontrollers executing code from solid state storage and pulling data directly from other solid state storage into hardware codecs without CPU intervention. They are designed to be as minimal, integrated, and most importantly, cheap as possible to accomplish that task, resulting in a feature set that is largely locked in at the time the ASIC is produced.
20 years ago, flash was slow and expensive, so you had to execute code from RAM. You also had to buffer large amounts of data into RAM so you could leave the spinning rust hard drive powered off most of the time (and to reduce latency). Finally hardware codecs were relatively rare and expensive versus a more powerful CPU so one could do it all in software.
Meanwhile. Those $20 shovelware players have essentially identical (and very lacking) feature sets, with the software written entirely by the SoC vendor and lightly skinned for each customer. The ESP32-based tangara uses a off-the-shelf SoM on a custom motherboard, but its software is completely besopoke and intimately tied to the ESP32 vendor libraries (many of which are proprietary) with a relatively limited feature set (vs Rockbox).
Rockbox directly supports several dozen different devices encompassing four major CPU architectures and can run bare-metal, on Linux, or any SDL-capable platform. It supports 1bpp-to-32bpp screens of near arbitrary resolution, has an extensive codec, plugin and game library, arbitrary button configurations, touchscreens and a fully themable, translated, and *voiced* UI. The only limitations are those imposed by the hardware. And every line of its source code is under a F/OSS license.
Can it be made to work on the tangara player? Absolutely! But the feature set (and performance) is going to suffer somewhat due to the ESP32's limitations.

« Last post by Oktan on April 06, 2024, 05:00:43 PM »My smart light switches use esp32 microcontrollers. Just because something was designed recently doesn't make it a good choice for audio playback or make it better than older hardware for a specific task. Microcontrollers especially are often very limited by memory, which is fine if you want to toggle a light switch.Yeah, but I mean, it's intended to be a music player.

Olympus - Installation/Removal / Re: M: Robe 500i hangs on white screen when try to boot Rockbox
« Last post by multiwirth on April 06, 2024, 04:14:07 PM »I hope everything works. Some time ago, I tried to swap the storage too, but caan't remember if I have ever succeeded or which adapter I used. What do you use?
Thank you very much, yes it indeed works pretty well!
I'm using an 64gb msata ssd on a cheap sata to IDE ZIF adaptor, together with another ZIF to CE adaptor.
Initially i wanted to use compact flash, as this sata solution already caused troubles with rockbox on my ipod video.
But the m:robe wouldn't accept any of my CF cards, except my 256gb card i already planned to use elsewhere.
Also it's limited to 128gb, but this CF card has been the fastest and most stable solution otherwise.
The SSD is really heating up a lot, even though the transfer speed never exceeds 1,3Mb/s
If that build works for you hit us up here with details and later on IRC when you have some time to test buildsSure, just let me know how i can help you debugging the issue.
Never used IRC before, but i'll have a look around.

Feature Ideas / Re: Keep custom audio speed setting during shutdown/reboot
« Last post by eugenkss on April 06, 2024, 03:16:39 PM »Thank you.
Yes, I know. This is how I currently do it, in conjunction with "Bookmark on Poweroff".
But if the audio speed was persistent, you wouldn't have to execute a bookmark each time on bootup.
You could simply continue to play, instead of "Home, 3x Up, Right, Right"
