[Q] Honeycomb on Nook running very slow - Nook Color Q&A, Help & Troubleshooting

I'm running deeperblue's honeycomb off an 8gb sd card on my Nook Color. Everything runs extremely slow, even things as simple as checking email, accessing the web, etc.
Any suggestions?

Try a different SD card. Cheaper cards are generally better for running a rom because they have a faster small block read/write speed. More expensive cards are better in nearly every other aspect then what you're trying to do. I run HC (Madcat's Hybird) of a class 2 4GB Sandisk card (about $15 at Wal Mart) and it runs great. My wife's running CM7 off an identical card. Both are perfect.

I'm running HC off a PNY 8GB class 4 card, which was $24 from Best Buy. Maybe I should try to format the card and start over? Should I install CM7 on the card as well? Not sure of the process to follow - can you provide a link?

I'll bet you need a different MicroSD card to solve your performance issue, as hockeyfamily737 mentioned above.
See this thread: SD Strange-results - or - How I learned to love CM7 on SD
to find out why.
This software : Crystal Disk Mark is what we are using to test card speed.
Office Max is having a sale on SanDisk class 2/4 MicroSD cards, 8 gig size, for 12.99 a piece until saturday, might want to see if there's one around you.
Having been in the situation you are in, the MicroSD card used makes a significant difference.
Also, try downloading the app "SD Speed Increase" by Diego Stamigni. Setting the cache size to 2048kb can dramatically improve performance on the card you are using now. It's one of my must-have apps for running android from the SD card on the Nook.
Edited to add:
I used to run the same honeycomb version you are, but I swapped over to Dualboot Phiremod / Honeycomb Image. I run it from the sdcard, and the phiremod version of cm7 is my new daily-driver. It's a great image, you might want to check it out.

also honeycomb isnt fully reeased for AOSP so the nook version is just a port of the SDK, also maybe try a class 6 sd card? you can get a class 6 8gig for like $18 of amazon, i use a class 6 and its very fast

[Q] microSD card problem

Hello,
I installed Android on my HD2, worked perfectly for 2 weeks. But my microSD was only 2GB, so I buyed a new one.
Kingston class 4 8gb microSD. Putted everything just on the new SD card, didn't changed anything! Formatted it also to FAT32.
Now the problem is that Android is VERY slow with getting out of standby, takes sometimes 10 seconds. I get a black screen for 10 seconds and then Android comes up.
Also starting up Android takes ages and it sometimes just freezes or gives a blue screen.
Has this something to do with Android or is the microSD card broken in a way? I can still move/delete files on the microSD card.
Anyone got at solution?
Thanks
Did you try a different build? Perhaps try Mdeejay rEVOlution build, fastest build i've used so far,very very fast, smooth and stable. Also try updating your radio.
I bet there are several utilities to test the read and write speeds on your microSD card. You'll need a cardreader in your pc to do that, trying it through WM6 won't work because the USB will be the one controlling the max speeds.
I hope this helps a lot of people struggling with the speed of android running off SD.
My suggestion is that the card size, and not just the card speed plays an important part in the speed at which android runs...
My Evidence. I first installed various builds on a variety of Sandisk 2GB and 4GB Class 2 cards. They all ran super fast... I mean no lag at all, ever. It might as well have been a Desire HD. Being that i wanted more space I used my 16GB Sandisk Class 2 that I have been using for WM, reformatted it and installed android. It was cripplingly slow. Unusable in fact. (i tried reformat/reinstall a couple of times before giving up). I then invested in a Class 4 16GB and installed the same build. Not surprisingly this was faster, usable but still not as fast as it was on the 4GB Class 2. I am going to go back the the 4GB card unfortunately until NAND arrives.

Thanks for the reply!
First i'm going to test the Mdeejay rEVOlution build, hopefully it will run smooth and fast. If not, i'm gonna send back my 8GB card and get a new 4GB class 4 card.
At the moment I'm running Froyostone 3.2, works now perfectly with the 2GB microSDcard.
I will post the results.

I totally agree with this, although I cannot figure out why.
I tested with two almost identical cards, both Samsung class 4, one 2Gb, one 8Gb, formatted FAT32 64k clusters via the same memory card reader/pc. The 2Gb one whizzed along with the build I'm running now, the 8Gb one occassionally stuttered and stalled. Seems odd to me, unless fragmentation comes into play maybe?
The only reason I have stuck with the 8Gb is for my music. Oh how I'd love to stick with my 2Gb card for the speed and have a second SD slot for my music.

Nook Color Desperation

Hey guys,
I got my nook color and 8GB Class 4 Toshiba MicroSD card yesterday, so I'm very very very very inexperienced at this. This thing is really cool, but I have some concerns. There seems to be a huge problem with my install.
Any time I use an application, I'm often plagued with popup messages that look like this:
============================================================
Application *insert application here* (in process *insert process here*) is not responding.
Force || Close Wait
============================================================
This has happened on Phiremod 7.1, CM7.03 Stable (Dalingrin Kernel OC-sd-042411ext4) , CM7.10 Stable, and Nightly 253. I'm using verygreens' generic-sdcard.img 1.3 installer (no CWM) on a non-rooted 1.3 nook color.
Phiremod 7.1 - Things were missing, graphical errors, laggy, etc
CM7.03 (+ OC Kernel) - Best so far. Things are pretty fast. N64oid runs well too.
CM7.10 - Very laggy
CM253 - Just as laggy as CM7.10
=============================================================
I feel like this might be a problem with my SD Card, but I have no idea. If it means anything, when I was playing Mario 64 on N64oid, everything was running smoothly until I decided to save the game. It froze until it was done saving. Also, downloading anything from the Market takes forever on 7.03 (like 1kb/s slow).
Any ideas on how to fix the applications problem? Any recommendations for a noob in general? What's a fast, reliable version of Cyanogenmod7 + Kernel to use on a nook color? I was overclocked to 1.2ghz - 1.3ghz on all of them.
Also, if I need to use CWM and install this to eMMC, is there a way to put the Nook OS on the SD card? I rather like it.
Thanks, sorry for such a long post

Sounds like a bad card to me.
I have class 6 8gb transcend cards in both my nook color and optimus v and they work great.
I'm still on CM 7.1 beta on my nook. haven't had a reason to update to release yet...
Download the Crystal Disk Mark benchmark software: Link Here
Benchmark your card, check my sig for the links to the two threads you'll need to reference to get through this.
Most likely it's your MicroSD card - SanDisk is the right brand to get if you need a new one.
Edit - I like CM7.1 stable for my Nook Color, i've been running it that way for a while. I've never rooted my internal memory.
I'm running from a class 4 SanDisk 16 gig MicroSD card - it runs great.
If using an older version of CM7, i'd recommend the app "SD Speed Increase" made by an XDA user, you can find it in the market. That change is baked into CM7.1 so running the app in that version is redundant.

Benchmarked my card through my nook and through my laptop's SD reader, here are the results of the QD32 Write Speed (since that's how the list is ordered in that one post)
Laptop reader - 0.007MB/s
Nook - Write Error
WELP, I guess it's the card. Got an 8GB C4 Sandisk off Amazon, should be here eventually. Thanks for the advice!

Also it is better to image the card through a real USB adapter rather than a built in SD card reader. That can give rise to problems, although, I think they are normally associated with failure to boot properly rather than instability which I'm sure will be solved by your new card.

Just curious why you recommend SanDisk as the "right" brand? I've only ever used Transcend and their cards work great. Does SanDisk have any specific advantages, especially for the Nook Color?

Do you notice anything different from beta 1? I was going to hold off upgrading until 7.2 (probably beta). That wireless adb thing looks too good to pass up.

I haven't been spending a lot of time in the Nook Color sub-forums recently, having gotten my hands on a smart phone (finally) i've been working on developing for that since the Nook Color is pretty much covered.
The reason why SanDisk is recommended above others is they've paid special attention to the physical bus size of the data pathways specific to small-block read/write file transfer on the card.
Android needs consistent small data transfer to run right, and most MicroSD cards are optimized for large-block file transfer, which uses a seperate bus in the card. This covers things like streaming media - recording from a camera, watching a movie, etc...
A majority of the application of MicroSD cards falls under that heading, whereas running the operating system from the card is a niche use for them - we just happened to luck out on SanDisk making a more rounded-out product instead of focusing on one aspect.
In my phone I run a PNY class 10 card, and it performs way better then the SanDisk cards - but that's because i'm transferring big files back and forth constantly. On the Nook Color, haven't found anything that comes close to the performance of SanDisk cards.
You could get lucky and get decent cards from other manufacturers, but the only one that consistently hits the quality mark we need to run Android from the card is SanDisk.
----
Given that i've been working mostly on my phone, I haven't kept up with the newer developments on the Nook Color too much, so still running CM7.1 stable, and probably will continue to do so until the next stable version is released - sorry I can't be much more help on newer versions.
I'll probably be more up date pretty soon, i've been cruising through here more and more recently now that we're getting other people to start in on dev work for my phone. Right now i'm pretty bottled up with a lot of work (from my job) on my plate, so I can't get much actual dev work done and i'm spending the limited time I can put into Android stuff on research again.
I can read through and learn stuff helter skelter and while out on the road and whatnot - but trying to write a kernel while on a break at work is a futile waste of time.
Edit -
The app Wireless adb, you can find in the market, is one i've been using for a while and it's included in my ROM for my phone, if you click the link to the ROM in my sig you'll find a link to the app in the google market and the developers website on the first post of the ROM thread.

I was having exactly what you have in mind now when I first got in this room.
I was "heck, what? I don't believe it, I have to try on my own before believing those guys" I actually bought 2 different uSD, Kingston and Transcend. One reason I hate Sandisk is MADE IN CHINA.
Anyway, off the 3, yes Sandisk yields best performance, technically, Blue6 already covered above.
And yes, I know it always seems like we advertise and work for Sandisk
No, we not.
We went through the hard path and we're passing the word of advice to new ones so they don't enter our own trails.

SD Card Partitions

I have a Nook Color that is rooted running CyanogenMod 7.1.0 on internal memory. I have a 16GB Class 10 SD Card in it and was wondering what people are using for partitions on their SD Cards. I have pushed pretty much every app over to SD Card but some (not all) applications (Google Maps for instance) seem really sluggish and many times it force closes.
Is the Nook just not powerful enough to run Google Maps or is there something I need to adjust? Maybe a bigger swap partition? I set them up quite a while ago and don't recall what I set them to off the top of my head.
Using CyanogenMod I am overclocked to 1.2GHz with the Governor set to Performance.
VM heap size set to 48MB.
Thanks
class 10 cards are not as good as you'd think for any Android device. Android devices tend to write smaller files... a class 4 card (Sandisk recommended) is actually best for these devices.

I am mainly using Class 10 as that is what I had laying around in the Micro SD Card Format.
I have a 32 GB Class 4 in my Thunderbolt and it is fine. Do you really think it would slow it down much if it is Class 10? I could always toss it in an adapter and use it in my Canon T3i.
This thread here explains what the issue is and will tell you how to test your cards out to see if they'll work. Basically that Class10 card only gets Class 10 speeds when transferring large files and for small files (like an OS/app uses to write temp files) you get crap speed. it's not normally noticed in everyday use because the files are small and a little delay writing it isn't noticed by the user. Class 4 cards from SanDisk seem to be overall performers for files of all sizes.

Hmm, that is interesting. Now does it matter that I am booting off internal memory? I am not dual booted and have CyanogenMod on internal memory. I am running Google Maps which is one of the programs that is really slow on internal memory. My guess is that what you are saying would apply because of the swap space being used on the SD card. I will say that my wife also has a Nook Color that I put my old 8GB Class 6 card from my old Nexus One in and hers seems to perform a little faster than mine. I haven't done the tweaks to VM heap size to hers that seems to have helped mine a little. So you may be on to something. I have a couple of these class 10 cards that I use on my Camera and have been happy with them. I think they are Samsung. The DSLR is 18MP so those files are pretty big so it might be just better to leave those cards for use there and get a couple of those SanDisk Class 4 cards for our Nooks.
Yeah, running apps from the sd would benefit from a fast sd card. When you get one, use CrystalDiskMark (pc) to check the 4k read/write speeds. I bought an 8gb and two 16gb Sandisk class 4 cards from Radio Shack that have reasonable speeds and work well. They're all in the .5 range for writes - not as good as some I've heard of, but they work well! Some (a Kingston and a knockoff Sandisk) I tested were as low as .006! I tried to use the Kingston before I tested its speed and got lots of instability and FCs. hth

[Q]Class 4 or 10 SD card or does it not matter?

Hi Folks, I recently purchased a nook color. I wanted to do the setup with cm7 or cm9 booting from SD. Leaving the emmc alone if i have it correct. From reading I am unclear as to which class of SD card to use for this process. Even though class 10 faster a lot of what I have read says class 4 works better with the nook color.
Any advice on which card type to choose would be greatly appreciated.
Thanks,

For SD installs, use a Sandisk class 4. It works better than class 10. They do not do well for the many small file read/writes which the SD install needs.
Thanks for the info leapinlar. I ordered the card.
Personally after trying a new Trancend class 6 which caused many problems in Rom running from SD, decided to try an older SanDisk class 2 card and after that everything was working fine.
Produced by NookColor at ICS 4.0.4
Class 2 or Class 4 cards work the best if you have the CyanogenMod mounted on it, it has been bench-tested against other higher class cards. Something about how android works better on the read/write speeds. Higher class cards work faster in other devices but not the nook color as a mounted OS.

MicroSD cards that work with CM10 for HD+

It seem that are still people that cannot get this to work. Most people actually stuck at creating a card w/ CWM.
I have this done relatively painless. I think most people forgot that the Nook itself is pretty much a linux machine. And with busybox, you can do dd command as well.
NOTE: this will simply wipe all your information the the microSD card.
Well you have to download both the cm-10-***.zip and sdcard-cwm-early3.img.gz files from verygreen.
Then I use 7zip to uncompress cwm file.
adb push sdcard-cwm-early3.img /data/su/
Go into the nook's System Settings > Storage Management > SD Card > Unmount SD Card.
adb shell su -c "/data/su/busybox dd if=/data/su/sdcard-cwm-early3.img of=/dev/block/mmcblk1"
remove the img file from the Nook if you wish using adb shell rm /data/su/sdcard-cwm-early3.img
**Now just wait, as this may take sometime as it write 100M+ to the sdcard. It will say something when it's done.
After that, you follow the verygreen step. What was posted above is for people who have problem creating cwm boot sd card.
Also notice that since you reboot into CWM, the current Nook ADB driver won't work, the system will recognize as a different device, you have to re-apply the driver again.
verygreen said:
Insert the card into the Nook and reboot the nook, CWM should start.
(This will also automatically repartition the card into a correct layout no matter the size (but no smaller than 4G).
In the CWM:
Go to "mounts and storage", choose "mount /sdcard".
Press power button to go back to the main menu.
Now do
Code:
adb push cm-10-XXXXXXXX-UNOFFICIAL-ovation.zip /sdcard
Also push whatever other zip files you want to install to /sdcard too.
(if you don't have operational adb, you can also just turn off the nook at this stage, put zip files to volume named "CM10SDCARD" (not "boot"), then put sdcard back into nook and start it again)
Next, choose "install zip from sdcard", and then "Choose zip from sdcard" and first cm-...zip, and then whatever other packages you have the need to install.
When done installing, press the power button to go one level up in the menu and then choose reboot.
This will reboot you into CM10.
If you ever need to get back to CWM later, use either "reboot to recovery" power menu, or reboot, and once B&N nook logo shows up, press and hold power and home keys together for about 4 seconds.
To reboot into stock nook software, just poweroff, remove sdcard, then poweron.

The real purpose of this post is to spread the information of which card work and which doesn't. I hope people can report in which card(s) work for you.
I personally have tried the Lexar 32GB Class 10 card and it works w/o any problem or show any lag at all.
If I can, when people post a working card, then I'll add it to the list.
Working microSD card list:
Lexar 32GB class10
Sandisk Mobile Ultra 32GB class 10 (reported by bunodosoma)
Sandisk Extreme Pro 16GB class 10 (reported by Chi Ahrens)
GSkill 8GB class 4 (reported by Chi Ahrens)
PNY 16GB class 4 (reported by Chi Ahrens)
I used verygreen's instructions to push CM10 on a Sandisk Mobile Ultra Class 10 32gb w/o too much trouble (CWM didn't recognize 1st CM10 push,2nd went w/o a hitch). Haven't noticed any lagging yet.
SanDisk Extreme Pro 16 GB class 10 ($50) works without lag. Couple of lock ups in HD+ within 2 hour period. Constant lock ups on HD. Maybe a bad card.
SanDisk Ultra 16 GB class 10 ($16) works without lag. Stable for 5-6 days on HD+ now. No noticeable difference in speed between the Ultra and Extreme Pro.
GSkill 32GB class 10 works without lag. Sequential speed is slow, but random 4k seems descent enough where there isn't any lag. Stable for 2 days on HD.
GSkill 8GB class 4 works with lag.
PNY 16GB class 4 works with lag.
AData 32GB class 10 - somehow became unusable during the process. Garbage.
Also, in Ubuntu 12.10, adb connects to HD+ only when started as root. Otherwise you get ???????????? no permissions. Ironically, adb can see the HD even when it's not started as root.

When do you see the lag ? Which specific operation ?
I did a boot time test using two different cards. Here are the results.
Start clock: When I press the power on
Stop clock: When I heard sound coming out from HD+
Sandisk: 53 seconds.
Samsung: 61 seconds.
I am not sure the performance advantage is mainly caused by 4K write performance on Sandisk card or the larger size(32GB vs 8GB) of the card.
Here are my two cards with CrystalDiskMark data, only tested 100MB data because Windows only see 109MB after CM10 is installed on the cards.

I have the SanDisk Ultra 64GB working without issues.
HD videos work great off it.
Plus it is formatted in ext_FAT, which allows use of the full 64GB and allows files larger than 2GB.
Works all very well in the Nook HD+.

Wait, you have CM10 and exfat on the same card? or you reformat the last partition to exfat? I'm not clear on that.

Does the nook hd+ regconize fully 64 Gb? because B&N said that its SD limitation is 32gb.

Yes, it see full 64GB. I have one on it as well, but I didn't try CM10 on that card.
The lag with the non-SanDisk class 10 cards is mostly felt in the browser - both the default and Dolphin. Lag in rendering html, scrolling, and also clicking links.
The SanDisk Ultra has been pretty solid however. I tried the San Disk extreme pro again to load CM10 on the HD, and it also experience random lock ups and reboots. I'm going to send that back and get another SanDisk Ultra for my HD.
The 2.0.5 update unrooted my HD, but Google Play still works without a problem. I just don't have su in the console. No big deal until I need root again. I did manage to get Chrome off of the CM10 and sideload it without a problem in 2.0.5.
My wife's HD+ has been running very happily with CM10. She's not quite as excited as I am.

I can also confirm that a 64gb card is usable with theHD+ but as above, ihaven't done CM10 yet. Just got the card and wanted to make sure it was totally compatible before I did anything else.

Looks like $10 and packaging. Both the same card.
Edit: someone0 already answered. Missed that. LOL.

To me the $10 card reader of some unknown quality isn't worth it. Save that $10 and pay extra for a better reader is what I would do.

Yes, it see full 64GB. I have one on it as well, but I didn't try CM10 on that card.

The nook should support exFAT out of the box, that's not the issue. The issue is that XP doesn't support either exFAT or MTP. The stock OS use MTP when connect to the PC, so you lose either way.

Actually, found a download by googling Windows XP exfat and there is an update that supports it: WindowsXP-KB955704-x86-ENU.exe I could read, write and format...

GSkill 32GB class 10 works without lag. Sequential speed is slow, but random 4k seems descent enough where there isn't any lag. Stable for 2 days on HD.

I second this. My GSkill card has been running flawless for two weeks now.
Sandisk 16G class 4 works fine.:victory:
Importance of 4k write speeds?
Hello, now that I've sorted out the problems with my class 10 16 gigs Sandisk card I decided that I'd better moving my setup there but since the move is quite a trouble I would like to know whether it would be worthwhile.
In other words whether the speed difference (between the two cards) is important enough (according to your experience) to every day tasks.
Here are the benchs from the card I'm currently on: http://i.imgur.com/sFVbu.png (~1Mb/s 4k writes)
And here are the ones of the one I'm thinking to move to: http://i.imgur.com/X5voM.png (~2Mb/s 4k writes)
....also if it's not to make enough of a difference (since my class 4 is already fast enough) I could/would opt to use my class 10 card as an external usb device instead (to use its fast sequential writes). So what would you recommend?
Thanks.
