I am using Tiamat 1.4.1 on my zoom and my /sdcard/external is functioning with no problems. Reads/writes, etc.

I believe the mass storage thing was for storage connected via USB (if I am wrong someone correct me please).
[Xoom Android Development] BGrutter:
All set now. I had to use SD Formatter to properly format my card. It's weird that my Xoom was able to see the .zip files while in CWM and even my DInc could see the files. Oh well, actually, there were two things I did differently this time. Maybe they will help someone else as I don't know for certain which did the trick (though I suspect it was the Formatter):

I used the prevously mentioned SD Formatter program.

While the Xoom was running, I pulled the card out (was afraid to do that before) and re-inserted it once I'd reformatted it and placed test files on it.

Hope this helps.

[Xoom Android Development] bignadad:
I see the new ota zip is posted. If we are on 1.4.1 what steps are needed to use that? Go back to stock and flash with clockwork?

Or do we wait for bigrushdog in incorporate?

EDIT...just saw his other post about not flashing :)
[Xoom Android Development] BGrutter:
Bigrushdog has already started that the new update comes packaged with a bootloader and will thereby restrict root access. He has warned not to flash it just yet.

Google also released the apk for 3.1, so I don't think it'll be long.

Yeah, that too.

[Xoom Android Development] andr0id23:
Uless anything has been updated, I don't think it will surely relock your bootloader, but rather there is a change(s) to the bootloader. While many think it will not relock your Xoom, you never know and I, too, am playing the waiting game to be safe. Actually I see a few threads all ready with the 3.1 zip so I'm sure there is a definitive answer out there. I am still waiting for BRD to give us word on how the new update will be incorporated with the tiamat kernel. Tho I am anxious for usb host mode and other goodies in the update, I think I can hold out a bit longer. I hope!...
[Xoom Android Development] bwcorvus:
It does relock...but oem unlock works fine.

There's nothing fishy going on with the bootloader, was a false alarm.
[Xoom Android Development] dj_ghosie:
Should just wait until the CWM zip is ready for all to use. Your Xoom or you aren't go die without the update, only function less better...

And I know when the zip will be coming, it's either 'tomorrow' or 'when it is ready'.

Just wait it out people!

[Xoom Android Development] futuregerald:
For the moment I personally am waiting for a CWM package but I'm still reading every thread I can find about other peoples experiences. Can't wait to get the update but don't want to lose CWM, tiamat, and SD =\
[Xoom Android Development] Lcsglvr:
So, this is my first Tiamat kernel installation for SD card support.

I am running the original kernel, I do believe. I have CWM recovery installed.

I tried to mount my USB storage, but my computer is not recognizing the drive. The drive that does pop up wants me to format.

I think I am missing a transition step from the original kernels to the Sd-card supported kernels. Can anyone help?

Thanks!!

Edit:

Nevermind. I don't have an SD card! But that should not stop me from updating to this kernel, should it?

Also, even if I don't have the latest kernel and CWM comes up with a flashable update.zip, it will not require this kernel, will it?
[Xoom Android Development] Elysian893:
It's easy enough to upgrade and get root back, just flash stock system.img and stock boot.img then update with CWM, then flash root31.img and push su/superuser.apk and done.
[Xoom Android Development] Elysian893:
You can't flash an update.zip with CWM without having an SD card in the slot... CWM doesn't care what kernel you run.
[Xoom Android Development] kev0153:
but can't flash tiamat over update, it won't boot, or so I'm told. Just going to wait.
[Xoom Android Development] Dubar:
I am in a similar situation. I can't seem to find an older version of tiamat that I can use to GET sdcard support. The link in the OP is broken, and kernel manager doesnt seem to do anything.

It seems I need an sdcard to flash the update that will get my sdcard working. :(

edit: ok seems like CWM will recognize the card regardless. Its a little wonky but I can work with this
[Xoom Android Development] hm1b:
BRD,

Are we getting something sweet soon ;-) I guess we got use to be the upper hand. We love your work.
[Xoom Android Development] MrHawaii:
This latest version is working a lot better for me. My Xoom still can't handle 1.5 Ghz as soon as I set to 1.5 my device freezes and reboots, but I am not getting nearly as much reboots as I was with the 1.1 version when setting Max to 1.2 or 1.4. I have been reading up on the differences of the governors when using Setcpu on their website but it does not have a description for the Interactive governor. Could someone please explain to me how the Interactive governor works and how it differs from the Ondemand governor? Thanks again for the hard work.
[Xoom Android Development] Mandelbrot.Benoit:
Well I've had two reboots at 1.2 ghz. Running for about 12 hours now. Everything is stable up to the reboot. Could be another app since I had same scenario with other kernal, but didn't have a single reboot on stock. Browser seems to be crashing a bit more.

Other than that this thing is perfect. Going to deal with it for now until something else comes along.
[Xoom Android Development] dch921:
From what I have seen posted elsewhere the interactive governor is in between ondemand an performance.
[Xoom Android Development] MrHawaii:
So it seems for me whenever this my device hits 1.5 GHz it freezes then reboots. When I use the Ondemand or Interactive governors, it will eventually go to 1.5 GHz even if I set the Max to 1.4 or 1.2. So it seems with scaling governors it will bump up to 1.5 even if it is just for a second, but because my device can not handle 1.5 it reboots. For about 12 hours now I have using the Performance governor with the Max at 1.4 so that it is at a constant speed of 1.4 while the screen is on. Using a profile exception screenoff with conservative governor with min speed off 600 so that when the screen is off it is running at 600 MHz.

I will report back with further usage.
[Xoom Android Development] el_bori1:
Just updated to 1.1.6 and in getting 3200 in Quadrant running @1504. No reboot or freezing.
[Xoom Android Development] Steady Hawkin:
I have not had a single reboot and is have been running @1500 for about three weeks. Best advice i could offer would be to redownload and repush the files, maybe you have a broken module.
[Xoom Android Development] MrHawaii:
IDK, I think my Xoom just can't handle 1.5 GHz. Sometimes hardware is different and can't handle the overclocked kernels. It was the same with my original Palm Pre. It could not handle too much of an overclock. I have tried to OC the Xoom to 1.5, with the original 1.5 kernel and the earlier version of this kernel. All did the same issues, but now that I understand what causes the freeze/reboot this kernel set to Performance at 1.4 GHz works like a champ.
[Xoom Android Development] xlGmanlx:
I think when you set it to performance your pretty much holding at the top speed. I do agree that different xooms react differently than others. It's a shame because mine stays oc to 1504
[Xoom Android Development] ericdabbs:
bigrushdog: The ocboot file that you used from coolbho3000, was it the v1 or v2 code that you used as your starting base? The reason why I ask is because it looks like on Feb 28th he posted a v2 which fixed some item.

http://xdaforums.com/showthread.php?t=972414

"2/28: Applied L2 prefetching patch. This increases Linpack to about 63 MFLOPS @ 1.5GHz. Flash the kernel and push the wifi module again: http://www.setcpu.com/files/xoom_ocboot_v2.zip (thanks ccfries for the heads up!!!)"
[Xoom Android Development] sfld:
guys im not new to rooting but i never use set cpu. i want to flash the best kernel and leavrle the cpu at whatever runs best... should i flash this kernel or the other one? is the other one not being developed anymore?
[Xoom Android Development] Steady Hawkin:
I have ran both and would reccomend this one. Personal preferance.
[Xoom Android Development] ericdabbs:
First question is do you have the wifi only or wifi+3g version of the xoom?

If you have the wifi only version, then you should flash tiamat's files since they have been proven to work. Not too sure if coolbho3000's files will work on the wifi only xoom since no one has reported it yet.

If you have the wifi+3g version of the xoom, then it shouldn't matter which version of the files you use. With Tiamat's files, you get extras because it comes with kernels to support things like usb hosting, advanced IP routing, openvpn, and windows netshare.
[Xoom Android Development] MrHawaii:
I first used coolbho's 2/28 version. Then I tried (I think) BRD's 1.1 version. Now I am using current version. All froze and reset at 1.5 GHz. With the other versions it would randomly freeze and reset after about 60 mind of use. Others have also experienced this (I think it was destroybmx) and I noticed when using the interactive or ondemand governor the device would go up to 1504 MHz even if I set the max to 1.2 or 1.4 (I think destroybmx noticed this occurence also) when checking the logs. So I guess for me as it is now my device unfortunately can't handle 1.5 and it is either the the Governors or the kernel (or a conjuction of both) that causes the device to go above its maximum settings. But setting to performance has been fine the device will be in constant 1400 MHz when the screen is on and (setting a profile) the device drops to 600 MHz when the screen is off. Those that have been experiencing these issues I recommend trying these settings.

Battery life has been fine. It lasted me all day yesterday. And I was on it a bunch playing Rom Gripper for about 5 hours (trying to pass Zelda).

Maybe I will try SBF back to stock and reflash this file when I get back from my vacation and have some time. But for me now it is fine.
[Xoom Android Development] MrHawaii:
For those of you that 1.5 works fine, could you try using Interactive Governor of Ondemand Governor and setting the Max to 1.2 or 1.4? Try running that for about an hour and then check the logs to see if your time in 1504 has gone up. This will give us a better understanding if some devices just can't handle 1.5 or if only some of them fluctuate above the set max speeds.
[Xoom Android Development] MrHawaii:
+1 for BRD's current version. Another added benefit is that it is set up for USB hosting. (I haven't used that though.)
[Xoom Android Development] Sandso9:

I have not seen any evidence he is maintaining his kernel. Tiamat is updated in nearly real-time as folks from AOSP commit to git. As of now, Tiamat is the only kernel available to wifi only model users. :D :D :D
[Xoom Android Development] Steady Hawkin:
I appreciate the hard work and your commitment bruh!
[Xoom Android Development] thunderstruck!:
Is it the kernel that keeps me from charging my Xoom via micro usb? If so, hopefully that obstacle can be overcome. I have a 1000ma usb wall charger, and it's a lot more convenient to use the standard cable I have at work than have to tote around the stupid proprietary charger.
[Xoom Android Development] Steady Hawkin:
No you can only charge via wall plug in or dock.
[Xoom Android Development] MitchRapp:

[Xoom Android Development] kcrudup:
FWIW- and if you KNOW what you're doing- I'm running my updated 3G Xoom @1.4GHz (mine doesn't like going any higher) with the kernel/modules listed in my .signature . I pull from upstream and build my kernels daily and will update that link every couple of days or so. It's the stock MR1 3G kernel but updated to 2.6.36.4, compiled with GCC 4.6.0 . (I'm 99% sure it will work for WiFi devices IF you use the WiFi boot scripts instead.)

This will tide over those waiting on a BRD kernel- BUT- I'm NOT supporting this here, and my SD-Card mounts in /mnt/sdcard2 .
[Xoom Android Development] Elysian893:
Excellent! Is 1.5ghz an option or is it limited to 1.4?

edit: Guess I'll know in a minute, rebooting after pushing modules right now :D
[Xoom Android Development] kcrudup:
It's hard-limited to 1.4- but if you build from the source listed in the GitHub link, I've added a kconfig option under CPU Power Management that'll let you fix it to anywhere between 1.0 and unlimited.

(I had to do it that way, BTW, vs. SetCPU or the init scripts 'cause I found out that the Flash will crank up the CPU to whatever the cpufreq scaler lists as maximum; I couldn't keep flash-intensive sites up for more than a few mins at a time.)
[Xoom Android Development] Elysian893:
The Xoom should have shipped from the factory at 1.4-1.5ghz, especially with the 3.1 update, man is it fast!

Quadrant score is still really low compared to where I was with 3.0.1 but the entire Xoom is faster so I'm ok with this. Scored 2532 with your kernel, I was at 3657 with Tiamat 1.4.1 on 3.0.1... Not that Quadrant is the be-all-end-all.

Also, I've got no idea how to compile a kernel from source, I'm assuming I'd need Linux installed on my machine and the knowhow. It's been since the 2.5 kernels since I've compiled one from scratch and that was an x86 build... Are there any guides for compiling Android kernels?
[Xoom Android Development] kcrudup:
Yeah, I could never figure out the Quadrant (and Linpack) difference between BRD's kernels and mine; even did a diff across both repos and there wasn't really anything different. I'm happy though, and left it alone.

One thing about this kernel is I'm experimenting with the new GCC 4.6 option "-Ofast", which optimizes for speed, vs. "-Os", which optimizes for size. You'd think the former would be faster, but the consensus has been for a while that smaller kernels are better 'cause of cache-hit locality. This change hasn't really made much difference in either Qd or LinPack scores, but I'm still playing around.
[Xoom Android Development] arrtoodeetoo:
Dangit! I'm stuck.

1. Reboot into recovery using quickboot or

2. Go into "mounts and storage"

3. Select "mount USB storage"

4. Your SD Card will now be mounted on your computer. Drop the kernel onto SD Card.

Not so. It says the disk is not formatted. I don't want to format it and lose everything on my XOOM.

What am I doing wrong? Do I actually have to have an SD card in the thing?

A question here regarding the best approach to take--

My wifi xoom is rooted and running Tiamat 1.4.0. CWM is installed and my sdcard works fine. Thanks!

Now the problem. I was doing stuff in Titanium backup and integrated an update for com.android.vending into the kernel (was that stupid?) Now, after many reboots and cleaning caches, dataetc...My Apps crashes every time and any recently downloaded apps crash too. Do I need to reflash Tiamat 1.4.0 to fix this? Should I go ahead and flash 1.4.1 (like I was planning to do)? Is there something else I can do to fix this? I've searched everywhere and can't find a fix that works. I can follow simple directions (like the ones in this thread) but I'm no developer (yet).

Please help...
