Title: [SOLVED] Installing to C250 V2 ; File Not Found when loading Firmware.
Post by: ScottMartin on January 20, 2010, 04:18:58 PM
I have tried to install the latest version of RB onto my C250 today and I seem to be having problems as well.

Downloaded the lasted C250 Firmware
Downloaded lasted RB software for C200V2
Downloaded mkamsboot and patched successfully:
>> [INFO] Patching succeeded!

Copied the outputed BIN file (renamed to C200PA.BIN) to root of device
Copied .rockbox to root of device

Ejected, powered on. Firmware updated successfully ...

I get the rockbox logo, then I get:
Loading Firmware: File not Found.

What am I missing?

Using U9.10, amd64. OS loads USB fine.

Regards,
Scott.

Usually that means you didn't actually copy the .rockbox folder to the device.  I'd make sure its there and that its intact.

Also, FWIW some c200v2s have trouble installing rockbox, but from the error message you got it sounds like yours isn't one of them.

I have read other replies stating that missing files are the reason, but I am looking right at it ;)
All the files seem to be the same as the Archive, sizes ... etc.

Any other thoughts?

I am correct in the DIR off the root is .rockbox (displayed as a hidden DIR in Linux)?

Scott.

That's my understanding.  So {mountpoint}/.rockbox (or whatever) should be populated.  Are there really files/dirs under .rockbox?  It's really a dir and not a renamed .tarball or something? 

Forgive me if it's too obvious, but sometimes I do a sanity check with something like:
file {mountpoint} to make sure I know what that entry really is
find {mountpoint} -print to make sure the system sees files/dirs there

I have the daily build running on my c240v2 but it really is unstable.  Navigates fine, FM is fine, but playback usually hangs on the 2nd or 3rd track played.  The UI remains responsive.

Yes sir, everyone is present and accounted for. It is a real DIR and not an archive.

btw, what file is 'not found'. A bit of a generic error. There should be more info.

Scott.

Does this make it more clear:

If it prints ok I'll commit it.

But yeah, you need .rockbox/rockbox.sansa

I wonder if it's a rockbox*.zip file for another target.  If so, maybe the BL is looking for .rockbox/rockbox.sansa and finding something else (or the filesystem is dorked so it can't read the rockbox.sansa correctly).

Well... that file does not exist. Did I forget to do something?

Is there another file named something like .rockbox/rockbox.ipod or something?  If so, I think it means it's just the wrong rockbox unzipped there.  That would be nice because it means you could clobber the existing .rockbox and unpack the right one there.   I think this is good news.

Nope. Perhaps I could get a dowload link. I was getting it from Daily Builds.

Post by: fratermus on January 20, 2010, 06:16:52 PM
http://download.rockbox.org/daily/sansac200v2/ is for the v2; we're assuming your OF was 03.xxxxxx or whatever

I opened up http://download.rockbox.org/daily/sansac200v2/rockbox-sansac200v2.zip and there was a .rockbox/rockbox.sansa in it for sure.

Added:  just installed the most recent daily build for c200v2; either it's a coincidence or it was more stable a week or so ago.  I can't even play one track now.

This download allowed me to boot thanks. It seems I had the wrong download.

[New Problem]
I think I am in the same boat as you though. Selecting a song just freezes, but I can still navigate.
If you find a working copy, I would appreciate a link so I can listen.

I just went back to the one from the 14th (24225) and it plays at least one song so at least you can hear the machine make music.  I just unpacked it on top of my recent build without cleaning out .rockbox first. 

2146028 2010-01-13 20:00 rockbox-sansac200v2-20100114.zip

I read somewhere that there's a place to find old daily builds but I don't remember where.  I searched the forum and found old (2007) references to an "archived daily builds" but the site seems to have been reorganized since then. 

I have that copy above I could email you if no one else can point us to a d/l link before then.  PM me with an email addy and I'll send it off.  I haven't used this site's PM function but I assume it'll work the normal way.

I think thats normal.  I don't think playback on the c200v2 works yet.

Do you have a link to the older builds? It was mentioned rockbox-sansac200v2-20100114.zip works.

Yes, I already tried these. Same problem or checksum errors were present.

Took me a while to respond to the PM, as I was away.  You should have the file now.

The version I'm sending definitely plays MP3.  You can play, FF/RW within and restart any particular file, but that's it.  It will advance to the next file but will not play it.

And therefore is not working

My playback is uninterrupted and continuous. So I can say that it is working for me.

This is only after downgrading to the version that was given to me:
rockbox-sansac200v2-20100114.zip

I think c200v2 is the most problematic of the Sansa AMS targets which have this playback problem (Clipv1, m200v4, c200v2).

So far we haven't found reliable actions/workarounds to make playback work fine or not.

On the ABI forums some told they had great playback on Clipv1 when not skipping any track, others told they had problems, some told the bitrate had effects etc...

But in the end I think each person had found some workaround but it would change with rockbox updates...

If you find a way to have somehow stable playback, I'd say stick with the current version you use, and share it anyway so maybe we could find some pattern which affects playback if everybody can confirm your results.

Just don't expect too much from c200v2 though.

Note: what does "alloc" say if you go in system->debug->buffering thread?

My Clipv1 says 0/394240 , so the audio buffer is 385kB, and I have very stable playback (these days, because it didn't use to be true).

I expect the c200v2 buffer to be much lower and I think this is the root of the problem.

Yes my alloc is very low compared to yours: 0/44592

current builds  should have a much higher buffer size: i disabled doom since it didn't work anyway and reduced the size available for plugins at the benefit of audio buffer

I have downloaded the latest version and it seems to be working just fine. I did have one song that it could not handle, kept jumping around .. but after 30 seconds, it went to the next track and has been fine for the past 2 hours.

Scott.

How big is the "alloc" reported to be after the change?  If its now comparable to the clip (~400KB) playback should be fairly stable as on the clip.
