Re: Update for Enhanced kernel for power users just released
 
I just read something two pages back in this thread that more or less confirms my frustration with the mind-numbing inability people seem to have to figure things out.

UBoot does not make charging impossible or a problem. Okay, I am pretty sure you can't boot normally, with the charger out, and then stick the charger in while it's on the uboot screen, and get it to start charging that way. But I know for a fact that if your N900 is off, and you plug it in to the charger, you will get a light-less uboot screen. Which, if you DON'T TOUCH, will complete its countdown and then load the kernel, which will THEN drop into the normal off-but-charging mode.

I don't know how you people didn't figure that out. Okay, maybe some hardware revisions play differently with uboot. Maybe. But I kinda doubt it. So what I really think is that the people who killed their battery unable to charge didn't have the patience to sit there for a few minutes after plugging in the cable when their device was off. That, or the kernel attached to their uboot was f'ed up, and then that's not really uboot's problem.

Maybe this weekend :p

v46 appears to work fine. On first boot of it the Nokia handshake video was truncated but the device continued to boot normally after that, I have the ULV 250MHz/1.1GHz as my default profile for Overclocking. It is running smoothly.

Note - I didn't have any showstopping issues with v45. I did have some weird charging issues such as a minute or two after hooking up the charger and getting the charge system sound and announcement that it was charging I'd get the system sound and announcement again. I trust these kernels so much I at first thought it was a USB issue. But there is no evidence to suggest this is the case.

Camera, Fcamera, BlessN900 all function as expected.

Instead of pulling from the devel repo and reporting problems with new features with that version. We should instead be reporting and Voting on version 42 in testing.

>> http://wiki.maemo.org/Extras-testing/QA_Checklist

>> http://maemo.org/packages/package_in....6.28-maemo42/

That way this testing version either gets promoted or bugs get squashed and the subsequent versions in devel move up the queue...

Those wanting to report bugs with the devel versions should:


Life as it should be. :)

For those interested in overclocking with PR1.3, version 42 in testing has worked fine for me with none of the other problems reported in this thread.

Camera works, mass storage works...
HEAR HEAR!!

I really wish there was a more foolproof and reliable method for people to do exactly as you suggest, but sadly people are .... not always that foolproof and reliable :p:rolleyes:

version .42 works beautifully for me as well and hasn't presented a lick of instability yet.

Well you can continue to have your doubts, but for me it's a reality that v44 with revision 2204 hardware did not boot. I have never before installed multiboot/uboot/nitdroid or anything like that. My SD card has just the single, factory default fat partition.

I got a problem in installing h-e-n.... anyone know what is the problem???

firstknight 2010-11-20 03:31
Re: Update for Enhanced kernel for power users just released
 
i install linux-kernel-power-headers... then install i2c...

my h-e-n worked...

so what is linux-kernel-power-headers needed for??

Then vote it up and simply copy and paste your comments from this thread. :)

The only foolproof and reliable method for people to do this, is to just begin doing this... Savvy?

I did find that the testing version 42, broke Jace's FMTXD binary since voting but, that is to be expected. I will reinstall his patch and see what cooks. I will then do the same... (copy and paste), my comments from this thread.

How is v46 of power kernel?

I was afraid of installing it...

greboide 2010-11-20 04:48
Re: Update for Enhanced kernel for power users just released
 
working fine, but i dont think it has too much difference from v45.


btw why are we using linux-2.6.28 when there is released linux-2.6.35, im sure there is a good explanation but dunno what it is?

I can't in good conscience vote on 42 when I went almost instantly to 46.

What is ur dev revision ? 2204 ? PR 1.2 ? Has anyone had trouble playing SDLMame or Mame with CPU at 1 Ghz and dualshock connected?

@ Geneven. What is ur device revision? PR 1.2 or PR 1.3 ? Do you play psx4all or mame with 1 Ghz overclocked?

The fact is, I did plug in the charger. Nothing happend. Battery stayed flat. Turning it on or off made no difference. Two hours or whole day. Still no difference. Many did have encounter this problem, or some conspiracy was going on with those club members.
Uboot is great, in principle, of course. But not every uboot build play that well in real situations. Just my 2 cents.

I want to know if it is safe to install Power46 on PR 1.2 dev rev 2401, I dont have fcam or bless installed any more, and should I upgrade from Power44 to Power46? Or uninstall first? Thanks any1 .

That must be it, the scores of people who had this issue must be idiots with the attention span of a goldfish.:confused: - you know some of these guys had a bricked phone for a number of days, you would have thought that one of them would have had the sense to plug it into the wall:rolleyes:

The fact of the matter is that U-boot did not play well with a pre-installed multiboot and folks could not load a kernel, and yes most of the people I discussed this with tried pretty much everything including your suggestion to get the battery charged, all of them had to get it charged externaly.

From my observations, I believe that some part of the kernel must be loaded before the device can charge - try it yourself, turn off the phone, plug it in and watch as the 5 dots appear before it starts charging.

That is not what the word bricked means. A bricked device is a device that cannot be revived at a (regular) user's home. If it only requires a micro usb cable and a PC (and a way to charge a BL-4J battery in the worse case) it is not bricked.

There is no problem between u-boot an multiboot. No program knows or cares if what is flashed in the kernel partition on the NAND is a linux kernel, or a u-boot that loads a linux kernel.

The problem that was with power44 was that the combination of NOLO and u-boot on HW revision 2204 leaves the system in a state that causes the kernel to hang at start.

The device can charge (slowly) if no kernel is running at all - there is a hardware component for that.

How do you know when it starts charging?

Re: Update for Enhanced kernel for power users just released
 
Just want to ask again: could it be some conflict between uboot and HW versions? If so then would it be good the mention the HW versions that have tested the kernel and uboot?

elipsoid 2010-11-20 12:22
Re: Update for Enhanced kernel for power users just released
 
Matan, on your first point its really a matter of interpretation, from wiki:
"When used in reference to consumer electronics, "brick" describes a device that cannot function in any capacity (such as a device with damaged firmware). This usage derives from the fact that some electronic devices (and their detachable power supplies) are vaguely brick-shaped, and so those which do not function are useful only as actual bricks. The term can also be used as a verb. For example, "I bricked my MP3 player when I tried to modify its firmware."[1]

In the strictest sense of the term, bricking must imply that software error has rendered the device completely unrecoverable without some hardware replacement. However, it is common to use the term for a problem which can be rectified but only by a complex and difficult procedure, often requiring additional software."


I wasn't aware that it was a conflict of the HW revision and V44 , it was an assuption that I had made regarding multi-boot.

Anyway - on the battery issue, I can confirm you are right. I am running V45 and have just left my device at the U-boot screen when plugged into the wall for the last few minutes (I have had to cancel loading by pressing a keyboard key periodically as it will only sit at the Tux screen for a little while before reloading). I then booted and opened BatteryGraph - it now has more capacity than when I first turned it off, so hardware is charging the battery.

However it don't understand why some people were claiming to have left their device plugged in for some time and were unable to flash, I doubt that they are lying. Perhaps the error, or reboot loop was in some way draining more power than was being supplied, the only way to check for sure would be to revert to V44 for testing.

Are there any easy way to install U-boot with power46 kernel?

Install power45. It's basically the same as 46 but with u-boot included.

Like said, go with v45. v46 only removes u-boot and adds capability for BT mice.

Edit: I seem not to be able to edit my settings as "kernel-config" is not found. Do I have to reinstall the power modules or something?

Yes, that is exactly what happened with my device, then I got a external charger and left for 2 hours, if we follow the instructions carefully after installed Flasher and have saved the FW image, just the comand and plug N900 , less than 2 minutes and the N900 is Up again.

@cincibluer6: Another thing, do you know if that bluetooth for mouse support in v46 means that I will not need to install those bluetooth HID scripts at all in order to get a bt mouse (or usb) working?
What does it mean?

cincibluer6 2010-11-21 20:46
Re: Update for Enhanced kernel for power users just released
 
@Larswad
I honestly don't know. I haven't even made the move for BT mouse on my laptop, let alone the N900. Might want to check the wiki or the main kernel-power thread for that.

There are a couple of BT mice that do not work with n900 because a bug in kernel, this is fixed in v46. It has nothing to do with bt-hid-scripts, despite the fact that more BT mice can be used with it.

reboot

then both OC and camera app should work fine.

Hi, i try install kernel power 46 but apt-get say Conflicts "kernel-maemo" and "kernel-modules-maemo".

I have Fcamera, mobilehotspot (cannot start shared wifi) and joikuhotspot work fine.

What application/packages i have to remove or update.

anyone help how to install? thanks.

My camera programs crash, too.

I started with a "vanilla" n900.
Installed Power Kernel 46.
Installed h-e-n.
Camera app crashes as soon as I open the lid. BlessN900 refuses to start.

Installed power kernel settings.
Still, neither Bless nor camera work.

/update:
Uninstalled h-e-n and i2c. Camera apps still refuse to work.


/update #2:
Quote:
sudo gainroot
apt-get update
apt-get upgrade fcam-drivers
Reinstalled the fcam drivers. Both the internal camera and blessn900 work again.

"apt-get install --reinstall kernel-power kernel-power-bootimg multiboot-kernel-power"

joshv06 said we must run this command but if i do it just reinstalls v45??

I tried to manually install v46 but with no luck! Gets stuck at the white NOKIA screen and then shuts down and wont go on again!
I have to reflash the multiboot kernel to fix it and then i can go into STOCK kernel

Any ideas how to get this v46 to work tia..

Guys

My phone keeps prompting me about the Enhanced Linux kernel update 2.6.28.10.

Is this safe to install?

I read on TMO some time ago an update screwed a few things up for some ppl.
