[Q] Running CM7 on EMMC seems slow...

I have been hacking my Nook with Cyanogenmod for a couple months now. I have tried running Froyo and CM7 on an SD card but I prefer to just have it flashed to the EMMC. However, it always seems that my nook runs choppy, laggy and slow. This when I overclock it as well. Am I doing something wrong to install it?
All I simply do is flash the newest Clockwork, boot into it, wipe System, data and cache, then install CM7. Once I get booted it seems like there is considerable lag in opening the App drawer, scrolling in just about anything.
I was watching some youtube videos of people showing there CM7 Nooks and mine doesn't even seem close to as quick... All EMMC installs should be the same right?
Thanks for the help!

I have noticed this as well.. I wonder what is it they do to get such snappy responses? Are you running 1300 mhz overclock? I also wonder if they have a different lag fix of some sort.

My understanding is that the eMMC is basically a soldered in microSD and it stands to reason that if you're using a better/faster external SD card, it should appear to be faster in most respects.

But I guess I am looking at videos like this one where they are running the OS from the eMMC and it is running like butter:
Sorry can't post link: but the name of the video is "B&N Nook Color Running Rooted Android Froyo 2.2 @ 1.1Ghz"
Mine does not go this quick at all...

I have not done 1300mhz, but I cant image that would fix the problem.

Yeah I have to admit, that definitely appears to be very smooth. When I'm scrolling through my various apps, it's nowhere near that. Then again I'm running CM7 off a 2gb SD card. Up until now, I've been under the impression that the performance was very similar between eMMC and external installs. Now I'm not so sure...

I had the same problem but I was installing wrong. I took wiping as just wipe data factory reset. When I reflashed I went to mount and formatted everything except boot it worked flawlesssly

I always do that too. In fact I usually wipe everything, then reboot back into CWM and then wipe everything again, then install. Seems like overkill I know, but I am at my wits end here...

damn me seeing those videos. I was happy and now I am going to have to figure out how to get my nook running that smooth.

Ug.. not really. The eMMC is basically an SSD memory chip; no hack jobs about this.

Well I have loaded Nookie Comb and it seems to be the quickest ROM that I have had on my Nook yet. I still think that it could be faster than what I am seeing but I am happier now.
Still can't get over the fact that people say that Cyanogen is smooth and awesome on the Nook and I haven't seen that to be the case at all. Either I am doing it wrong or I am just incredibly picky or something!

Actually, Kadin is essentially correct. Embedded MMC (eMMC) is not a raw flash memory chip. It's is a flash chip with built-in controller that interfaces to its host using the standard MMC Plus interface. Replace "MMC Plus interface" with the very similar "SD interface," package it a little differently, and you have an SD card.
That said, an eMMC device very well could have controller and/or organization optimizations that make it better at hosting an operating system than most SD cards.

The EMMC is very slow unfortunately. I've seen a write speed of only 2mb/s. That's worse than most SD cards. Class 2 level.

Would I be better running everything off a SD card?

Goodbye Nooksters!

I've had a lot of fun with my Nook, and have made all my friends envious. But the thing that dampened my enthusiasm is the poor battery life. I am running CM7 off of a micro SD card, and I swear, I have to fully charge this thing every other day ... and that's with minimal usage.
I also found the screen size kind of tiring for any lengthy forays to the Internet, and was constantly hitting the wrong links on pages because the text type is so small (yes, I did frequently zoom in when I had to).
Well, I've been sitting on the fence about buying a 10-inch Honeycomb tablet, and doing a lot of research in the meanwhile.
But today I got the push I needed when I opened up my email and received a $100-off coupon for any tablet at Staples. So, I hopped in my car and picked myself up a shiny new Samsung Galaxy 10.1. Have only played with it for a few minutes and it's a lot different than my Nook, so I've got some learning to do.
Meanwhile, my girlfriend is going to be pretty excited when she finds out I am giving her my NC. She's been bugging me for one ever since I got mine. But I may take the SD card out and let her use it stock. She's still have Internet and email access, but the battery life should be a lot better.
Thanks to everyone on these boards who have helped me with my questions.

Everyone has their own preference on screen size (7" is perfect for my needs, 10.1" would annoy the hell out of me), but if you expect better battery life with another device...well, good luck with that. =)

1. compare the Galaxy to the NC is apple to pineapple.
2. 10" is bigger than 7" for sure but the trade off is the weight. Can't use it to read when laying out bed
3. Imaging if the NC has $100 off, B&N will burn their stockroom quick.
Anyway, enjoy your Honeycomb tablet.

Oh, btw, I personally think you g/f will jump up/down asking you to give her the Galaxy

You had a good run. Good luck! Personally, 7" is about right for me for something I commute with. Battery life has been fine but I have CM7 on the eMMC so perhaps that makes a difference.

You've probably heard it before, but if you're still using the last stable version, cm 7.0.3, update (for your gf ) to the 7.1 RC1 or Nightly 136. With deep sleep fixed, I've gotten as much as six days of light use out of my NC.
If you're using verygreen's SD image, you'll need an update for that, too, toward the bottom of his OP in that thread.

I'll never understand the point of people that put up threads saying they've decided to with another product.
Fine, the Nook didn't work out for you and you found something better for your tablet needs. But honestly why do I care? I just don't get it.

If you'll be sticking with CM7, do her a favor and put the latest nightly on it. Dalingrin's OC kernel is included now and deep sleep has been fixed since the last stable release.

Nook's size is perfect for me. Battery life hasn't been a problem. The only thing missing for me (and I really mean the only thing, since I'm not looking for a tablet as a laptop replacement) is a means to make Skype calls. We're close with the partially functioning usb, but not there yet.

Bumping up the resolution to 200 or 220 will fix these problems. I'd do this before giving a Nook to anyone. There is a free app in the Market called LCD Density that will do this temporarily. To change the resolution permanently is only a small modification of the build.prop file. EX File Explorer, also free in the Market, will allow you to do that. There are many threads on XDA that will tell you how.

Dalingrin's OC kernel was rolled in as of n132 - all subsequent builds have it, including n138.
FWIW, my battery life is every bit as good with the latest nightlies as stock, if not better.

Wait, why wouldn't the people who put out the various roms already account for that? MIUI 1.7.15.1 is set to 240.

you should have waited few months and spend same money for quad core ICS with higher res screen. or at least wait couple months for honeycomb dual core omap 44xx like archos g9. in any event overclock the tegra2 and you're probably going to find battery life not much better than cm7 nook color. good luck to you.

Because it's a matter of preference? I have no problem with the NC's default density.
ETA: and a lot of people like a density right around 187, which makes everything a bit bigger without screwing up the status bar, widgets, layouts etc.

[Q] Root or android on sd? Sorry if it is asked before.

After smashing my netbook I am finally getting a nook. I have 2 in mind but I have a quick question that I can't seem to get an answer to, which is better?
Nook Color Dual Boot Android on SD card
or
Nook Color Rooted Android Gingerbread?
Can you guys give me the pros and cons for each? Am I really missing anything by not having the ability to use the nook UI?
Thanks in advance,

Not unless you want to use it really as an e-reader.
I prefer CM7, but it is really up to you and want you want. You can always load up CM7 on an external card and try it, then decide if you want rooted stock or CM7.

First thanks for replying, I think I would like to use it as an e-reader but isn't there apps that do that anyway? Is the nook e-reader UI that good?
I am worried about warranty etc.

Yeah there are tons of apps for reading but for some reason people like the stock UI. I personally do not. Also you don't have to worry about warranty as the nook is unbrickable and if you have a problem you can just flash back to stock.

Yeah, I have CM7 on the SD card, so I could switch back to the stock reader if I really wanted to. But I haven't yet. The nook app is reasonably well done - I have a few issues with browsing the BN storefront from the app, so I prefer to do that online, add to wishlist and then buy from the app. Also you can't do the read-in-store from the android app. Still, like I said, I haven't booted back into the stock ROM yet, CM7's so enjoyable.

Ok, I think I might go for the sd approch at the start and go from there. One more question. Can I place anything on the internal space that will in turn be seen on whatever version of android I'm running on the sd? eg:videos/music?

One more thing to consider.....
If you are going to use the stock reader often and do not set up a dual boot system you are left with removing the card every time you want to use the stock system. In time, that may likely result in damage to the card reader. I have CM7 on the eMMC and a card for storage and have not touched the card in 2 months. It just stays in the reader.

The Nook app will not allow you to play "enhanced" children's books from my understanding. Only the stock reader will.

I has a Nook Tablet!

Stopped by the local REI for gear. On the way home, stopped by B&N to see when they'd have a Nook Tablet for me to play with. Manager states they have one in back....I have a geekgasm (tm), she says: "This was ordered by someone and then cancelled...so *technically* its already sold. Long story short: I just brought it home!

Ok, out for beer and then back for play.

So is the charger the same for it and the nook color?

Appears to be identical.
Front bezel is rubberized like the back - much better grip.
Speaker slightly louder, microphone hole nearly invisible.
Screen clearly better.

thats cool!
I didn't know that they were available yet.
I just got a nook color for my wife and I am in the process of reading lots before I root it.
It is going to be an xmas gift for her.
I figured I would take a little bit of time to work out all of the kinks before I give it to her...lol

What kernel version does it have?

She'll love it: my Nook Color has been awesome and its kinda sad to retire it.

Can't find any place in the stock ROM that tells me, do you know where to find it?

Will it boot from a bootable SD card?? (..at least to CWR to verify hacking will be as easy as the original)

If you go to settings there is a line to touch that displays the software info, at least that is how it works in the NC. I don't have a stock one with me to verify.

Also it be pretty cool if you found the kernel version. Could possibly help us nook color owners expedite the ICS/HC update process.

so you like the nook color more then the Kindle Fire?

Check out this post on the nook tablet forums.

No software info - closest is device info and that doesn't have it.
Software version is 1.4.0

I can't really answer that, as I've never used a Kindle Fire. I did consider both before purchasing, but the Fire lost my interest when I found out it had no microSD slot. Additionally, I *really* love my rooted NC, and the NT just adds more speedy goodness to a platform I already love.

To all that asked about SD card booting - I tried the CWM sd from my NC and the tablet completely ignored it. As it has been pointed out that CWM is built for each device, this result is unsurprising.
NOTE: despite having 16gb of on-board storage, stock ROM only allows you access to 1gb. While this will, without question, change once rooted and ROM'd, it is somewhat disappointing.

Just an update: installing other launchers and sideloading/usb debugging achieved. No luck yet with Gingerbreak or Super One-click.

So far, according to this thread from the NT forum, the Tablet appears to require a signed bootloader

[Nook HD] Sirius XM App not working on CM10.1

I did a search and couldn't find anything about Sirius XM not working on the Nook HD/HD+.
I'm running the HD w/ CM10.1 and every time I log into the app it says "service not available". I seems like I had this problem on CM7 a long time ago but can't remember what I did to fix it now.
There is a thread on the Nook Color forum too but it hasn't been resolved as best I can tell.
Anyone else know why this is a problem and/or what the fix might be?
Thanks in advance.

Maybe your ansver is here <- its about CM7

Hmmm, now that you post that, I seem to remember monkeying with the IMEI number to get it to work. Thanks for the tip. I'll take a look at that and see if it makes sense to me (can barely code myself out of a paper sack).
I'm assuming that just using the CM7 framework.jar file in CM10.1 would be like crossing the streams and all life as I know it stopping instantaneously and every molecule in my body exploding at the speed of light.
