Re: New Nokia N800 Firmware to fix SDHC Bug Released
 

I agree with Texrat that the problem *should* be fixed now.

However, the official "release notes" with the bugfix is at least confusing and questionable:

QUOTE:---------------------
This new release (version number 4.2007.38-2) provides a software fix for a bug which may have appeared while copying large amount of data over-the-air or from external SDHC memory card to internal memory or vice versa. In some cases the downloaded data may have corrupted.

This new release fixes also a bug which drops in some cases voltage from memory card, though cards should manage this kind of situations without corruption.
---------------------

So, the last sentence should be the actual bug that was fixed. What bug the first sentence is referring? Was there another bug that I'm not aware??? :confused:

I blame Finnglish. :p

Hi Fanoush,

Thanks a lot for the effort to give us the flasher.

Really appreciated.

Hi,

After the update is done shouldn't you delete the two files downloaded to save space? I mean is it safe?

Just curious..

Hi Mlhouse,

Thanks a lot for hosting the image.

Maybe this is a little OT but do you think your point back to: http://www.internettablettalk.com/fo...8223#post58223
is still needed with this kernel? I notice that after flashing only the kernel, my setting @ 1000 remains. Should we reset that back to default?

Thanks again,
Chris

Re: New Nokia N800 Firmware to fix SDHC Bug Released
 

OK, so this firmware supposedly fixes the SDHC bug(s). But has anyone actually tried using a SDHC card yet? I don't want to install the new firmware until someone else has tried it out with a large capacity card. Any guinea pigs^H^H^H^H^H^H hands-on end user reports?

Re: New Nokia N800 Firmware to fix SDHC Bug Released
 

Well, I'm posting this from an n800 with two Kingston 8gb sdhc card installed. (Root partition is on the internal card also.) No problems here. I built an identical system for my business partner also, and she's doing fine as well. However, I think the Kingston cards may be safer then others relation to the bug fix.

Re: Fix for the memory corruption bug!
 

Only the MMC/SD corruption issue is addressed in this new firmware (specifically with kernel changes and nothing to do with WiFi) so yes, I'd say the WiFi timeout tweak is still neeed when using the new firmware/kernel.

Your setting @1000 remained after you flashed only the kernel because the gconf settings are stored in your rootfs. If you had reflashed the entire firmware on to your device, your settings would have reverted to the default (200?) and you would no doubt experience WiFi connection problems again.

Milhouse your contributions are highly appreciated.

Re: New Nokia N800 Firmware to fix SDHC Bug Released
 

From following the reports in bugzilla it appears that the problem was reproduced and understood at Nokia the moment a certain Michael (IIRC) posted a report where it became clear that the card corruption was happening when the N800 light dimmed a certain time window after data was written to the card. Only then it became clear what was happening. It wasn't just a question of 'write a large file to the card, damm*t!' or some such.

You needed to have the conditions set up like described above to reproduce the problem. _None_ of the steps-to-reproduce posted earlier had included the user's light timeout settings, not to mention actually describing the connection to the light dimming. In light of this (no pun intended) I find the whining and yelling from some posters quite uncalled for. Instead, virtual beers and cheers to the bugzilla poster which actually came up with the _true_ way to reproduce the problem!

Re: New Nokia N800 Firmware to fix SDHC Bug Released
 

Now I'm wondering if my extended timeout settings are what prevented me from experiencing the card problems... probably so.

Re: New Nokia N800 Firmware to fix SDHC Bug Released
 

so my question is, am i (or any of the rest of us) going to get reimbursed for the card(s) burned by n800s? seems to me something should be done about that.

Re: New Nokia N800 Firmware to fix SDHC Bug Released
 

As explained before, the avenue for reimbursement lies with the card vendors.

Re: New Nokia N800 Firmware to fix SDHC Bug Released
 

I recall someone testing this theory out and it did indeed help... maybe a quick seach on forum can find out... :rolleyes:

Re: New Nokia N800 Firmware to fix SDHC Bug Released
 

"As explained before, the avenue for reimbursement lies with the card vendors."

This is too terse. You figure out why; I'll adopt your policy and just provide my conclusion with no hint of my reasoning.

Re: New Nokia N800 Firmware to fix SDHC Bug Released
 

It's not *my* policy. As for being too terse, that's simply because I see no need to completely reiterate what's been mentioned numerous times already, including the reasoning. No offense intended.

Re: New Nokia N800 Firmware to fix SDHC Bug Released
 

I'm still getting corruption and crashing after applying the update. Which is extremely annoying, as I'm about to go on vacation, and being able to have a bunch of mp3s and some video was the whole reason I bought the N800. Has anyone else had this problem?

Does this help?

Re: New Nokia N800 Firmware to fix SDHC Bug Released
 

It sheds some light, but since the last post was on 10/12, I'd think that most people aren't still having problems. My symptoms are a little different after the firmware upgrade - before, individual files and some dirs became corrupt after Canola rescanned my library, but this happened quietly, and I only noticed it as albums dropped out of the list. After the flash, (and with a new 8Gb Transcend card), Canola's scanning again causes corruption, but with more serious results - the N800 locks up on the NOKIA boot screen, and after a minute or so, powers down. I just reformatted and checked the card under OS X, and it seems fine, so I'm trying again, this time with the card's lock switch on (though I'm not sure that'll save me). -T.
