Sandisk Sansa e200R

[Bagder]

If you can install Rockbox using the e200 installation instructions, you do not have a e200R model.

Does it truly say e280R when you connect it to USB? Does it reveal only one partition when you do "fdisk -l" on the device?

We've seen other guys have what looked like refurbished R models where the vanilla version has had a Rhapsody logo on the back etc.

Here's the easiest way to tell if you have a true R series: If you have the Rhapsody Channels option in the main menu of the original firmware, you have an R series. If not, you have a vanilla.

I've had read about the sansa rhapsody player in the sansa port section and regarding about the bootloader,I read in some part of that article,that the player has its own memory and a ram,that ram is a like the ram in our pc's but is backed up by a battery,if you dissasemble a sansa you are going to see at the front something with some masking tape,remove the tape and then the battey,if you want to get the bootloader,as I've read it is stored on a ram,and the ram's are volatile,so if you cut the power is going to loose the info stored on the ram,so I guess that is going to help to develop the rockbox for rhapsody,thanks for reading this and wish luck to all.

X86: unless you can back up something like that with real world facts, it is just a wild theory together with all the other wild theories.

A unit is likely to be able to survive a total battery run-down.

The bootloader we've extracted from an R model was copied from its RAM, sure, but we can copy the vanilla one the exact same way and that's because the bootloader is loaded from the non-volatile place into ram.

badger sorry if I said something you didn't like, the idea just came to my mind,I'm going to think about that,I have a ruined sansa wich I dont use,I'm going to use it like a test hamster,count with me for this,I want to colaborate in this project,damn it,sorry again,I just wanted to help,I don't know something about programming but I can help simulating scenarios in my mind,doing aproximations and analysis about something in matter,count with me,sorry if I made a mistake.

I'm Bagder

This thread and all other places we read stuff about the e200R is littered with people speculating and throwing out wild ideas or crazy things claimed to be facts. We all have an obligation to pause such behaviors and stop and think a little before we post facts we believe we might have read somewhere.

That's the main reason why I bounce on all weirdo claims posted here. I'd love to see new break-troughs and interesting new angles on how to get the R models hacked, but we need to filter out all the junk along the way.

[X86]

ok bagder I understand,I'm going to think before I post something may become into junk,I'm going to dissasemble my sansa to see it analyze it and I'm going to do some research,I want to help to get rockbox running on sansa  rhapsody.

[e280ruser]

Yes, sorry, but I think that it is a refurbished E200, only with the rhapsody logo printed on the back side.  It does say e280R, when I mount it, however, there are 2 partitions, the fat32 storage partition, and a hidden OS/2 partition, which I guess holds the original firmware(?).  Sorry for any misplaced hopes in regards to making that model work.  I guess I will need to get a hold of a REAL e280R and get to tearing that thing to shreds to try and figure out what is hindering this model from working, which will hopefully lead to some kind of a hack to make it work.

i don't know if i'm slow or not making any sense but i've found out that if you change the file extention to .txt you can read the info in the file.
if you've already covered this well you don't explain things to people so how would i understand?

[Bagder]

i don't know if i'm slow or not making any sense but i've found out that if you change the file extention to .txt you can read the info in the file.

What file are you talking about and how is this really relevant to get Rockbox to the R models?

And we can read all files no matter what they're named...

A plea for some help from one or more e200R owners:

Can you please use e200tool while in manufacture mode and dump the i2c rom (with i2cdump) and make it available to me?

[clutch]

If no one else does it by morning.  I'll give it a go.  My box that dual boots to linux is currently re-encoding some video.  Hopefully there are not any issues using FC5.

Okay, killed the encoding.

Used this on my 250R to enter manufacturing mode:
This mode requires a special driver or tool to access it, and I just got a complete system lock when I tried it without one!

    * Power off
    * Turn ON lock/hold
    * Hold down center select button
    * Insert USB cable

Got this:

[wess@localhost ~]$ ./e200tool i2cdump mysansa
e200tool v0.2.3-alpha (c) by MrH 2006, 2007
Dumping i2c rom (address=87) range 0x0000-0x2000 to 'mysansa'
Searching for device 6666:e200 ... 9 8 7 6 5 4 3 2 1 0 not found!
[wess@localhost ~]$                                

I pulled the battery and it came back to normal.

When I plugged in the sansa in normal mode I got this:

system:/media/sdb1

Fedora Core 5 automounted it just fine.

I'll be up for a bit longer.  I only sleep a few hours at a time so I'll check for advice in a few hours.

It's been a while since I played with this... I guess you need to use 'init' first, before i2cdump works?
