dual boot to rhapsody firmware

[alaron]

Hey xoring,

Thanks for making that clear I'll update the code to date and build a bootloader and it should dual-boot properly and have that pixel corruption you were talking about fixed.

[xoring]

Update: I now have a fully working pp5022.mi4 that fixes the pixel corruption.

svn up -r 14423 rockbox/
svn up -r 14620 rockbox/firmware/target/arm/sandisk/sansa-e200/lcd-e200.c

I posted the file at the same place as the previous one.

Hey, |Rain| showed up on IRC (http://www.rockbox.org/irc/reader.pl?date=20070927#23:01:47) and provided a patch that might work. It basically disables the microsd card (and doesn't start a thread) for the bootoader:

(I don't think it has been posted to flyspray just yet)

It would be great if you could try this on a fresh SVN checkout on an e200R player.

[xoring]

Bagder: I just tried out that patch (svn up && patch -p0 < booloader.patch). I didn't get any errors when I patched or compiled, but the resulting bootloader causes my e200R to freeze on the first SanDisk logo-screen. It doesn't load either firmware.

Hi guys

I can confirm that neither the bootloader build from HEAD or the one patched worked, both froze at the Sandisk screen. So it's not the patch who's freezing, but the HEAD source.

I've tried Xoring's posted bootloader and works fine on mine, I can dualboot but I have 1 line of corruption on top of the screen. If we could fix that...

I think xoring's bootloader was built off an older code base...not the from HEAD, am I right?

alaron, did you try the new one? I posted one at 2am EST that fixes the corrupted pixels.

[alaron]

nope I tried your first one
I'll try your new one now!

[alaron]

Perfect xoring, that bootloader worked fine no pixel corruption!
I wonder why the HEAD source doesn't work since I was thinking to get the latest version...

You have your sources sync'd to an old revision...

svn up -r 14423 rockbox/
svn up -r 14620 rockbox/firmware/target/arm/sandisk/sansa-e200/lcd-e200.c

If I have time this weekend I'll try to play with the sources a little bit.

Thanks Xoring!

The problem with the boot-up freezing at the logo-screen was fixed in HEAD so I gave that patch another try and got the original problem again. It boots Rockbox fine, but not the OF.

[alaron]

Thanks Xoring

This morning when I tried HEAD was broken for us they put up the fix really fast.
We can probably trace the problem in the simulator and fix it...if time permits

[alaron]

Anyone knows if this bootloader would work with a newer version of the original Rhapsody firmware which is:

Product: e280R
FW: 01.02.031
Region: America
Build Date: 2006.12.14

Thanks

[xoring]

why not try it and find out for us. worst that can happen is you have to re-install, but after the ordeal with the bootloader you should be very familiar with the unbrick/reinstall process.

[alaron]

Where can I get a newer Rhapsody version from? Sandisk's software will detect they have a newer version and will ask if you want to install it but that will not work with out setup. I need to get the actual .mi4 file and place it inside System folder.

I'm willing to try if I can get a new firmware version.

After a few minutes on the official website I found this...

[alaron]

Tried it and works fine

Thanks Xoring!
