Double boot on X5 ?

[Eldreamer]

I've made a short press... The monitor showed me black lines and no turning on and the pleer had gone to off-state.

Finally.
I've made one short press and at once short press again. it run up brilliant.
What's the trouble?

My version: X5 60 Gb (with radio)

I've tried to full charge the iAudio. Hmm... The same problem. It starts up 4-5 times from 7  attemts. In any way.. Where can i find old version of dual-boot with REC button?
Please help.

I think you're pressing the on button for too long.

If it's pressed for more than 25ms, the OF is booted; alas, the OF shuts itself down if you don't hold it for ~1 sec, resulting in symptoms as you described.

First try to flick it as fast as you can to verify this, it'll be easier if you can learn the correct timing

If you really want it to wait some more, you'd have to compile your own bootloader :
Get and apply FS#5289 (may 12th comment), change the constant in the calls to preloader's sleep() in crt0.S to something more than 25 and compile.

The old (deprecated, not supported even by me, just don't use it) REC version is there as well, at the top.

Dear RaeNye!

I'm not a super-user. Would you be so pleased to make a precompiled "x5-dual-bootloader.bin" with 0.75 sec for RB and more time for OF.
I will appreciate you.   Please help me.

My contact e-mail: eldream@e-music.ru
Hope for you help.

[RaeNye]

Sorry, I don't have my RB setup on this computer.

No special privileges are needed to compile a bootloader, just get the source code off CVS, apply the patch and compile. If you have problems, come to IRC and ask there.
Another option is to ask for it on iaudiophile X5 RB forum.

BTW: You can't change the timing for the OF without further investigation.

May be someone else could help me..  
Please...

Dear RaeNye,

Is there a patch file of the current version of the dual boot for the current version of the RB bootloader in which I can adjust the holding time for booting the OF (that often mentioned 25ms)?  Can you please point out what I need to change in that patch if it is not all that so obvious?

Cheers.

Read my message above (from Dec 18).
It is probably out of sync but easily resync'ed.

[winnyec]

Yes, I have read that, but you have posted the stable version on 5th August in this thread, and even there on Flyspray there is some follow up and you refer to some other post here, which leads to the precompiled version on 5th August again.  Does it make no difference?  I.e. is the difference in mkboot?  Many thanks.

[RaeNye]

It's a later compilation with no actual difference (maybe something did change with mkboot, I don't really remember that).
I tried to get rid of the OF dependency on later version, but that never worked out and the only stable version is May 12th's.

Sorry for being a pain in the arse, but I am really a rookie to this, and my programming abilities suck.  So it seems that the stucture has change to some extent; I checked the dual-x5.patch file, and the

Code: [Select]

 /tools/Makefile
  /tools/configure
  /firmware/boot.lds
files seems to trivial how to change.  However the crtical crt0.S has been really restructred.  Am I right in guessing that now the

Code: [Select]

 /firmware/target/coldfire/crt0.Sneeds to be changed?  So that your code is pasted right after the

Code: [Select]

start:?  In which whenever the code

Code: [Select]

 pea (25).w
  jsr sleep
  addq.l #4, %sp
appears, this 25 needs to be changed to larger value?

If I manage to compile to the whole thing, is there a way to test it before flashing to my player?  If still the player fails to boot up in any way, is there a way to put either RB or OF back so that something at least would work?

Thanks really a lot.

[RaeNye]

You are right in all assumptions.
Note that IIRC the constant 25 appears twice, change them both.

You can't test this offline, but even if you totally mess things up, you'll still be able to reset device, enter USB mode and reflash another firmware of your choice.

Feel free to post the sync'ed version back to flyspray (#ifdef the dual booting code so that the code would compile on other coldfire platforms as well).

Hello ppl,


im new to this at all but here´s my question. Can anyone tell where i can download the latest dual bootloader file. I already installed rockbox but now i want to try out this dual bootloader with the original firmware. Anyone knows where to download it? I have a X5.

Hi All! I'm new to Rockbow and after one day figuring out what it is, one more reading forums I still can not find the latest RaeNye latest dual bootloader file.

The ones who where in this thread are said "deleted because obsolete", well good to do that but WHERE is the new ones...

iAudiophile seems dead (you have to be a member to acces downloads, and for 6 hours now I still didn't got any actiation mail ;-( )

Anyway it is an independent site, should we really go there for something born here ?
Well  guys claim it loudly and clearly if this subject is politically incorrect but why can't this just be on the downlaods part of the site under an "UNSUPPORTED" chapter ?
Where can we (newbies like me find the files to even try this mighty dualboot on X5 ?)

Thanks.
