iriver H120 after CF mod: *PANIC* error dc_writeback_callback ()

[Bilgus]

IDK its been forever since I saw the stock bootloader

instead of deleting and copying try renaming .rockbox and copying

I bet it failed to delete/overwrite

I'll try this later.

What I did right now is repeating a full Write & Read test with CheckFlash, but this time "as physical drive (NT-based systems only)" because I thought the CF card IS a physical drive in the H120... the test started with full of errors... does it mean that the CF card is defective or is it the wrong test procedure?

So... it's been a while, I tried some things out and here is my update (spoiler: still no success yet).

I bought a similar CF adapter like the one from dealextreme from a german shop I luckily discovered, it seems to be from another factory (https://www.m-ware.de/adapter-und-konverter/mini-ide-adapter/compactflash-an-1-8-hdd-adapter-von-m-ware-id6882/a-6882/). I also purchased another kind of adapter CF to toshiba 50 pin (https://www.m-ware.de/adapter-und-konverter/mini-ide-adapter/compactflash-an-1-8-toshiba-hdd-adapter-female-von-m-ware-id7595/a-7595/). Finally, after some testing, I also bought a second CF card (Transcend 133x 32GB). Long story short, all combinations resulted in the same problem, which is hanging with the mentioned error pretty quickly when playing or skipping tracks (sometimes with the new card just endless hanging without error occurance).

The 1,8"-CF to toshiba-hdd-adapter did'nt work with both cards, giving me a -ata 11 panic error immediately after booting.

Strange thing concerning the idea to try rockbox version 3.9.1: even after full erases with special software and reformatting rockbox still told me in system menu that it was 3.14?!

I run out of ideas now... I think it is pretty sure that it is not the card or adapter, is it? Sure, I could go on buying further CF cards, maybe with other writing/reading speeds or capacity or models/manufacturers, but obviously this is not such an attractive idea. Has anyone a helpful thought about this -ata 11 error or rockbox 3.9.1 not getting installed?

Another thing I just discovered: Here is a patch for CF card using https://www.rockbox.org/tracker/task/8644. Unfortunately, I don't really understand what's it for and how to use it. The patch area in the wiki is not understandable for me... https://www.rockbox.org/wiki/WorkingWithPatches. May anyone help and tell if this could be a promising thing to try?

[Bilgus]

well besides being 10 years ago it is a promising avenue but it'll either have to be applied to the source from 2008 or dissected and added into the code at HEAD.

Without having a device in hand it is hard to dev something like this..

[It looks as if its already been added..]

[entne]

Sorry but I don't get the meaning of your post?! 

[Bilgus]

that flyspray patch has already been merged into Rockbox..  (So it won't do any good to add it again)

[entne]

Just recently I realised why other rockbox versions weren't recognized and always 3.14 was displayed as the installed version... after copying the .rockbox folder I should of course have booted in disk mode which I didn't. Well, I did now and the writeback error or some similar freezing persisted in all trys (3.14, 3.9.1, recent dev build, Bilgus' modification build). I thought maybe it would make a difference if I flashed one of these versions to RAM/ROM as an "update", meaning that following the CF wiki guide I executed RoLo (in disk mode) and wanted to reflash. With 3.9.1 RoLo gave me a "checksum error" and I am now ruminating if it really makes sense trying the procedure again with dev or modificated build. On the one hand I don't have much to lose, on the other I am afraid of completely breaking something... what do you think? Or other ideas?

Has anybody a hint concerning the following questions:

1. What does an ATA -11 error message mean? I get it when using this adapter: https://www.m-ware.de/en/adapters-and-converters/mini-ide-adapters/st5051-cf-to-2-5in-hdd-adapter-id7595/a-7595/

2. Can RAM/ROM be flashed with older versions of rockbox or with dev builds to try these out? I currently have 3.14 in flash.
