HOW TO: Install Rockbox

[mountainlion]

Thanks for getting back to me. I replaced the binary in the rockbox folder but I still get the same error message.

Scrap this post - false information provided as I lacked understanding =)

@Bullseye, mountainlion:

I need you to try going back to a vanilla "legacy" D2 firmware (eg. 3.59 with NO Rockbox or multiboot), then install the patched Rockbox 3.59 (NO multiboot) and see if this works. Only then should you try installing a patched D2+ firmware.

@andrewthecoder:

The .rockbox folder won't make any difference to this error - it happens during initialization of the NAND driver in the bootloader. This is before it even mounts the drive, let alone tries to access the right folder...

[andrewthecoder]

@shotofadds:

hmmm... Care to explain (perhaps in a PM?) that to me please? As the only place I find that string is in this file;
http://svn.rockbox.org/viewvc.cgi/tr....c?view=markup

Which (correct me if i'm wrong) has nothing to do with the bootloader.

In fact I've just re-confirmed my thoughts by testing a rockbox binary on my D2 which was built after lowering the "MAX_WRITE_CACHES" from 8 to 1 - it gave the panic message as expected. No changes to the bootloader there.

[shotofadds]

Open a patched firmware in a text editor and you'll find that string too! The NAND driver _has_ to be included in the bootloader, otherwise it wouldn't be able to load and run the actual Rockbox binary (rockbox.d2).

You'll still get an error after reducing MAX_WRITE_CACHES to 1 in the main binary, as the NAND driver is included in both the bootloader and the main binary - and both need to work properly!

I tried all 3 builds Andrew and got the same error message. I assumed I should rename them rockbox.d2. I might try a different f/w later tonight or tomorrow shotofadds. Is there any point in trying an older d2+ f/w?

As you may see from the above post(s), I have just learned that was completely pointless, sorry. ><

See, my understanding of Rockbox is very limited, that was just a haphazard attempt before shotofadds got a chance to reply.
The rockbox binary itself has nothing to do with the error you are getting, they are caused by the bootloader (which is patched into your Cowon firmware).

So what shotofadds has asked you to do is eliminate all possible causes of the problem by reverting to Cowon firmware 2.59 or 3.59 then repeating steps 2,3 and 4.
If the problem no longer occurs with the original ("legacy"?) D2 firmware, then it means patching the rockbox bootloader into the D2+ firmware causes problems.
Either way, I know it is hassle, but as a process of elimination it would be very helpful =)

P.S - @shotofadds: to repeat the big button that says "Thanks"... thanks =)

[Bullseye]

I will do it in a few days. I need time to do so. If that fixes the problem (reverting back, then using D2+ FW) I would be quite happy.

Will keep you informed.

Now we need the Multiboot version for x.11 firmwares. Thank you for your hard work.

No problem, thanks for reminding me about the latest firmware version(s).
Uploaded =)

[andrewthecoder]

Just an update; All of the bootloader-patched firmwares have been updated to use the latest (revision 21549) bootloader.
For some, this may fix problems (I think?)
Either way, figured updating was a good idea. =)

[Bullseye]

Forgot to mention it here but with the last change shotofadds did I no longer have the *PANIC* message and my rockbox works.

Thanks again shotofadds

Hi, I also have a problem with Rockbox:

I have a D2+ with FW 3.11, installed the patched firmware, it also upgraded correctly. I then copied the .rockbox to my D2, but it doesn't load. Am I just unable to use the hold switch correctly? I have also tried reinstalling, deleting rockbox and copying it again.

Thank you in advance for your help.

[andrewthecoder]

Ignoring the rockbox folder for the time being, are you saying that when you perform steps 1 - 4 and switch on the D2 then slide the hold switch, it simply boots into the Cowon firmware?
If so, I may have screwed up, lemme go check =)

[maedden]

Yes it boots the cowon firmware. When I copied the patched firmware I downloaded, it said "upgrading firmware" as it should, but it keeps on booting the cowon one instead of rockbox.
