I had this problem after flashing BRDs 3.1 update, wipe and reflash solved it. Your Xoom isn't by chance constantly hot around the Verizon logo on the back? Mine was always warm and never entered idle according to the battery use, but I was never able to pinpoint why even with Watchdog.
[Xoom Android Development] Brolloks:
Yeah, I ran it again and got 3800, I'm happy now:)

Use common sense... Let's keep this on topic, guys. Posts about other device deleted.

Edit: and to keep this on topic myself, look what happens when you OC the GPU... http://nena.se/nenamark/view?version=1&device_id=325 :-)
[Xoom Android Development] arrtoodeetoo:
Sorry, I forgot to follow up with my question. I asked if I need an SD card in the slot to install this kernel, and got this answer.

I actually just want to use it for overclocking and all of the other goodies until I can get an extra SD card. How do I apply this kernel without the use of Clockwork Mod?

Thanks!

issue with one of my SD cards...

Just a lil problem I have been having with one of my SD cards. I have a 8GB class 6 Transcend and it works fine. I have a 32GB class 10 Patriot and it is not being seen at all. Both are formatted as FAT32 and I can read the 32GB on my PC fine. Is there any limitations such as block/allocation size? Any ideas or suggestions would be appreciated. I will continue to look for a solution and will post if found.

Thanks go out to the devs involved with this release!
[Xoom Android Development] Vanhoud:
I thought id share an experience I had regarding the SD Card and 3.1/Timat Kernel. Not sure if this can be fixed via TIMAT or if this is a basic 3.1 issue (because it also happens when stock). Check out the link below

my quadrant score is 2687 after 2 runs

I'm on 1.4ghz

is this normal?
[Xoom Android Development] AceXMachine:
Yea, I figured out the hot swap issue (I was initially curious if it worked like that so I tested that out first). But I cannot mount in Recovery, get a generic error. So I removed the 32GB Sandisk from my Thunderbolt and put the Patriot in and the Thunderbolt said it was damaged and had me format it, so I did. This is interesting because Windows 7 found no problems with the card when I did a full scan and format with it previously. Now that the Thunderbolt can read it, I'm trying it the Xoom as we speak....(a few moments later) ok, it mounts in Recovery, rebooting....(a few moments later) and that does it. That is very strange. I have never had a format done in windows not work for a phone where a phone format did work (unless I was dealing with ext/sd-ext). Now I'm really scratching my head...

You are definately onto something Vanhoud
[Xoom Android Development] tinpusher:
You could try to set a "screen off" profile in setcpu. I underclock mine way down when the screen is off. Im too lazy to do an actual test to see how much battery life it saves, though.
[Xoom Android Development] Brolloks:
How do you OC the GPU?
[Xoom Android Development] siscim23:
Did you flash a boot img from the third post of this thread before the kernel?
[Xoom Android Development] b0ricua:
I can confirm that a screen off profile saves a ton of battery. I fully charged last night and used lightly yesterday and today and my battery is at 93%. I'm also at 1.6ghz and under clock to 456mhz when screen is off.
[Xoom Android Development] wsuo2006:
That's amazing. Did you run airplane mode?
[Xoom Android Development] h_zee13:
Yes I did. I used the wifi only boot.img. the one that turns the charge light on. Then I flashed the kernel.

I now flashed the 1.6ghz and set it to 1400 with setcpu, I'm getting quadrant result average of 3600
[Xoom Android Development] flombs:
Is it safe if you set a screen off profile to the lowest possible MHz in setcpu?
[Xoom Android Development] zonk7ate9:
There was a screenshot earlier in the thread from an app called CPU Spy where it showed how often your process spent at certain speeds and only only 3 sppeds really registered 216, 1600, and deep sleep (idle). I've experimented with a profile like this on my phone, and in my opinion it does nothing. A well designed kernel will manage this for you. Doesn't the Xoom have like 14 day standby? It will only use a few percent a day while sleeping and the less background updates you have that wake it up, the better.
[Xoom Android Development] willverduzco:
Hang around the irc channel or wait until it's tested enough to be incorporated into BRD's main post. :-)
[Xoom Android Development] twinkyz1979:
I have been having some annoying slow loads of market and browser pages that I never had before flashing 1.4.2. I have also got it clocked to 1.6Ghz and have never gotten a score above 3700 on quadrant. I have also noticed considerable more lag in switching between pages on the home screen.

Is there anyone else having these problems or know of a fix to them?
[Xoom Android Development] mbroeders:
First, did you install the proper boot image first and then the kernel?

Second, it may be that your Xoom is just not running stable at 1.6 ghz, try downclocking it a little, see if it runs smoothly at 1.2, then try 1.4...
[Xoom Android Development] igor.tonky:
naa, forget screen off profile. i have mine on 216-1.6 interactive, and standby drain is 1mA, losing like 1% in 5 hours.

something was eating his battery, like app keeping xoom awake, or wifi scanning for networks. try setting wifi sleep to "when screen off", in wireless -> wifi -> advanced.
[Xoom Android Development] twinkyz1979:
Yes I flashed everything right. I will try to turn down the clock and see what happens.

I do however have 1 other question. Besides the clock speeds is there any other differences in the 1.4ghz vs. the 1.6ghz kernels?
[Xoom Android Development] mbroeders:
No, not that I know of. It there was, I think if there was a difference, it would be mentioned in the first post. I did not notice any differences myself...
[Xoom Android Development] 379767:
Exact same issue, exact same card, used SDformatter... Problem solved

Search for sdcard.org
[Xoom Android Development] despich:
Well I figured this out and I am a little pissed that I didn't figure out what was wrong with the instructions before I ended up wiping it. Because even after wiping it and starting over I had the same problem. Nobody replied to my question either which didn't help.

The problem was all in the "adb shell push su /system/bin" command that I have seen in multiple places. It should be simply "adb push su /system/bin". Maybe it's just me but I don't see how the instructions could possible work as written.

Anyways all is well the ends well, I got 1.4.2 installed and am running along fine at 1.6 Ghz and over 4000 on Quadrant tests. Plus my charging lite works again!

Running a 32GB LEXAR SD card formatted Fat32 using the default settings on an XP box and its all working well
[Xoom Android Development] AceXMachine:
I'm sorry, if I had seen this sooner I would have told ya. I just subscribed to this thread for my own SD Card issue so I missed your original post but I did notice the "shell" command being there when it shouldn't and was actually on my way to post just that when I realized you were just quoting your original post (I got an email notification which didn't let me read the whole thing...). I made a itsy bitsy mistake (don't ask lol) when rooting my xoom after the 3.1 update so I have "adb push..." on the brain with as many times as I ended up doing it lol.

Anyways, sorry I missed you and glad you figured it out!
[Xoom Android Development] EwanG:
Everything has been running very smoothly with 3.1 and the 1.4 GhZ kernel. I am tempted to try the 1.6 kernel, but would like to avoid doing that just to find that my system might be one of the unstable ones. I assume Moto set these at 1.0 originally so they could use a variety of chips without having to worry about whether they could clock faster or not.

Is there any program you can run that will test your Tegra to see how stable it would be at 1.6 short of flash the new kernel and pray?

TIA!
[Xoom Android Development] despich:
Worse likely schenario if it's not stable at 1.6 you can still go into recovery (using the volume keys on boot trick) and download and flash the 1.4 kernel. The tablet doesn't kick into 1.6 speed until it boots and setCPU cranks up the speed. It's hard to believe it would be that unstable that you couldn't boot and get into setCPU and turn it down temporarily until you get the other kernel flashed.

[Xoom Android Development] b0ricua:
Yeah, I usually never bother with a screen off profile as most my Evo kernels have HAVS which undervolt by default. Wasn't sure if Tiamat did so I set this profile up. I've been experiencing great battery life so didn't change!

Dan, I did see where someone corrected the instructions (in a thread not OP) to remove "shell" but obviously you had to figure it out for yourself.

So much to learn...

Glad you solved your problem!
[Xoom Android Development] GulMiguel:
OK, I confess to being stupid and perhaps missing where this may have been posted before. However, I've gone through all the steps to get the new kernel. However, I can't find my sdcard on the system (meaning the additional one that's supposed to be sdcard/external). Where should I be looking for it? Did I miss doing something that would have allowed this to show up?
[Xoom Android Development] okantomi:
I don't know. It just shows up as sdcard/external, on the same directory level as your apps and media folders (Movies, Music, goodies) and so on. What was your flashing history? I flashed Tiamat 1.3.0 (???) which I think originally enabled the sdcard/external and then to 1.4.0, 1.4.1, update to HC 3.1, then Tiamat 1.4.2. I don't know if that made any difference. How did you update to this kernel? if you flashed the zip using CWR, obviously your CW recovery sees the sdcard or you wouldn't be on the new kernel, right? So it wouldn't be a physical problem with the sdcard.
[Xoom Android Development] ankorez:

thank you very much

3 days than i search...without success

ok so i dont always keep up to date with new versions and im on tiamat 1.1.6 (rooted awhile ago) and i cant find the older versions or tuts on installing them. i dont have sd support and all the methods are for current versions w/ sd support.

if some one could direct me to the method/instructions would be greatly appreciated! thx!

USB Ethernet for USB Tether from phone to Xoom

In the OP, BRD states that USB tethering has been implemented on 1.4.2.

I just made a USB host cable following this guide > http://xdaforums.com/showthread.php?t=1068197

I also downloaded Gscript lite and tried to follow the few simple command steps in the referenced thread above. But.... nothing. It says, "Select a file ( .sh from sdcard )"

Could someone be kind enough to explain to me how to set up/enable USB tethering from my rooted Droid Incredible (running CM7) to my rooted Xoom (HC 3.1, kernel 1.4.2, wireless only).

Thanks, in advance.

Question...

I just installed this kernel (1.6ghz one) and my quadrant scores, with SETCPU 2.1.3 settings at 1600mhz on performance, are only 2700. How are people getting 4000+??!!!
[Xoom Android Development] siscim23:
Did you flash the new boot img?
[Xoom Android Development] boredmug:
Same Here. My quadrant scores are way lower than they were with android 3.0 and previous kernel. I'm right around 2700 also and I've noticed my xoom has become stuttery at times. Maybe it is related to set CPU? I never had these problems before 3.1 and newest kwrnel

EDIT: didn't flash the new boot image. Thanks. Quadrant now around 4100
[Xoom Android Development] lrs421:
For Some reason I'm experiencing some lag today in the launcher running at 1.2. May not be a kernel issue though.

Processor overheating with 1.6 Ghz OC?

So I've been running the 1.6 Ghz OC kernel for a few days now, and while I LOVE the performance (by far the best performance I've seen thus far on my Xoom) I'm growing a bit concerned with the heat being given off by the processor after moderate extended use. I know it is the processor that is heating up because the heat is only building in that area of the device (lower right area if you are facing the screen in landscape). Anyone else experiencing this? I mean obviously one should expect some heat from an OC'd processor, but this is the first time I've noticed this (never happened back when I was running the 1.5 Ghz OC. Thoughts? Should I be concerned? For now I'm thinking about dropping down to 1.4 Ghz until BRD releases the new 1.5 Ghz version.
[Xoom Android Development] tribalb:
I've been getting it today since I got to using it more. Im on the 1.6 ghz kernel. Just flashed the 1.4 ghz kernel. Im gonna see if it still does it

*edit* so looks like for me the 1.4 ghz would be a better choice and no reboot. What's odd is I'm not even OC'ing my xoom. Hope this insight helps others choose the best kernel for their xoom.
[Xoom Android Development] SemperAndroid:
Anybody have link to the required boot.I mg that needs to be fpashed before installing the kernel. Just want to make sure I am using right one.

[Xoom Android Development] dscribe:
Thanks for the 1.5 GHz kernel BRD! I did a quick run and got over 4K (don't remember the exact number) by putting processor in performance mode. I'm going to run with it for awhile and hope I have a daily driver here.
[Xoom Android Development] dscribe:
In what mode are you running the CPU? If you run in performance mode it will stay clocked up to max all the time. I could see where that would cause excessive heat and battery drain to boot.
[Xoom Android Development] hoppie2828:
For my own edification, what is considered "normal" or "expected" for temps when you OC? I can't seem to find any clear documentation on what is even considered a safe temp and what is a temp you really dont want to be going over or maintaining for extended periods.
[Xoom Android Development] lrs421:
I'm currently using the 1.4 kernel. I maxed the speed at 1.2 but both system panel and setcpu show my processor hitting 1.4. What did I miss?
[Xoom Android Development] joeski27:
Yup, been running in performance mode :cool: ....tonight I'll have to try on demand or interactive and see how that goes.
[Xoom Android Development] willverduzco:
Do not use performance governor!

Guys, there's ABSOLUTELY NO reason to use performance governor other than for benchmarking.

You're going to waste a ton of battery this way and will not benefit from any noticeable performance or responsiveness gains. You should use interactive for day-to-day, as it strikes a great balance between battery life and speed.

Additionally, the Tegra 2 has wake-from-sleep issue with performance governor, as do several other SoCs such as the Samsung Hummingbird. The alleged SetCPU issue isn't a SetCPU issue at all; rather, it's a SoC/performance governor issue.

In short, DO NOT USE PERFORMANCE GOVERNOR (other than for benchmarks)! That is all.

[Xoom Android Development] airbillion:
Brd,

Thanks for all your hard work! How does this affect the battery? Also, will this work with the speed_autoscale boot.img you put out for testing in the irc channel?

Thanks
[Xoom Android Development] bigrushdog:
Well, about that battery... Naturally, scaling to higher frequencies consumes more energy. Also, it looks like 3.1 itself sips a little more juice. So, i think it's safe to say your battery life is gonna take a hit. Wait till I get 1.7 going! You're gonna have to just keep it plugged in!
[Xoom Android Development] airbillion:
Cool can't wait! Thanks for the reply

[Xoom Android Development] jase33:
As long as you have flashed the image file you from the OP once you will not need to do it again to change these kernel versions

**On a side note, I found this boot animation while I was web-lurking at THIS place..**
[Xoom Android Development] EwanG:
Do you even need SetCPU with these kernels? It seems like it boots already OC'd?
[Xoom Android Development] Stealyourface:
My "external" folder doesn't read any sd card anymore. I had it working fine with a 4GB then I put in a 16GB I just bought for my xoom. They both read fine in CWM, but don't work in HC. Tried reflashing the kernal. Didn't solve the problem. Ugh...I'm sad now.
[Xoom Android Development] cam30era:
Have you tried formatting the new 16gb card in another Android device?
[Xoom Android Development] arrtoodeetoo:
Can someone please post step by step instructions for installing this kernel without Clockwork and an SD card?

Thank you.
[Xoom Android Development] Stealyourface:
I have not. But that still doesn't explain why the 4GB that worked previously, does not now. And why they both work fine in CWM.
[Xoom Android Development] jase33:
you don't need it. the kernel will auto scale. setcpu gives you other controls like profiles, govenors and underclocking.
[Xoom Android Development] cam30era:
You should format your 16gig card in an Android device. Every card is different. CWM can often read a card that can't be read from the booted OS. This has resolved issues of this type for a lot of people. Give it a shot, you've nothing to loose.
[Xoom Android Development] Stealyourface:
My 4GB was formatted in android, doesn't work. My 8GB that I'm using in my android phone, doesn't work. Formatted my 16GB in my phone, put it in my xoom, doesn't work.

So I'm assuming BRD set his kernels to automatically OC? Is the default clock speed something that would be set by the kernel? Because on my Nexus One running Cyanogen it seems like the phone will only go up to 1Ghz unless I turn it up with SetCPU.
[Xoom Android Development] bwcorvus:
No the ones you download from here are oc with app only. We are testing one that has oc on by default.
[Xoom Android Development] starcms:
Are you serious? Sorry but you will receive none of my patience. Have you not read ANY previous posts or even tried looking for an answer yourself? You NEED an SDCard. :rolleyes::rolleyes::rolleyes:
[Xoom Android Development] zonk7ate9:
Yea, thanks... that didn't sound right to me because I always thought I had to force the OC with SetCPU, and I just tested with the new 1.5 kernel and it was at 1Ghz at boot. As always nice work guys.
[Xoom Android Development] gerald410:
How would or can you control the gpu oc?
[Xoom Android Development] starcms:

[Xoom Android Development] mbroeders:
A little more on topic, overclocking the GPU. How would that affect battery life and lifecycle? Does it have a major impact on both aspects?
[Xoom Android Development] RinTinTigger:
Sure it has impact on both.... but you are on your own to decide if it fits for you.

As the battery life is real big on xoom, the affect OC has, cant be that big. At least if you set your cpu governor to powersave, it will get you a less big affect un your battery.

speaking for life cycle....as noone has reached the lifecycle's end...no one can tell on that. But driving a car on train tracks, just because it can be driven faster there, may hurt the car though :)

Haha, thanks. I've OC-ed to 1.2 and battery life still is amazing. I was just curious if GPU OC would have extra effect. But I guess I'll just try and see for myself...
