last_kmsg is missing

Does anyone (Verygreen) know how to get the last_kmsg to work? I just get an error about corrupt header and bad data in the kmsg and there is no last_kmsg. The exact message is:

<6>[ 0.884124] ram_console: got buffer at 90000000, size 200000

<6>[ 0.884124] ram_console: uncorrectable error in header

<6>[ 0.884338] ram_console: no valid data in buffer (sig = 0xb999b89a)

<6>[ 0.901519] console [ram-1] enabled

This happens using the latest nightly or my own builds. The lack of last_kmsg is hindering my building of cm-11.0. I can get a clean build porting over FatTire's Encore code and Hashcode's Amazon code but it just bootloops. I don't think any kernel changes are required for cm-11.0. Without a last_kmsg I can't figure out how to debug it. Maybe a serial console through the headphone jack? Or a framebuffer console? Last_kmsg would be the easiest. I might have a problem with fstab or something, I just can't debug it without last_kmsg. I'll push my current progress up to my github account so others can use it but it isn't anything earth shattering. I'll let everyone know if I succeed at building cm-11.0. I just can't get past the bootloops. I hope that getting a last_kmsg will let me get it running.

Also, is the recovery.img that we build with cm functional? If I try to use the new cwm that comes in cm-11 I also bootloop. Could be the same kernel problem.

Hangouts YouTube Force Closing

I have seen mention of Hangout Force Closing in the thread but no solutions which isn't that big of an issue seeing as I don't use it on the Nook HD+ anyways but YouTube constantly force closes on me - is there any solution to that?

I'm on 10.2 1203 nightly.

Thanks!
[Nook HD, HD+ Android Development] huntz:
It's a shame. After 4 days my CM10.2 degraded into a not usable state :crying:

The problem is WIFI. Now I'm again with 10.1.3 (thanks to my nandroid backup).

With CM10.2 (updated to 12/02) I was not able to download the last nightly (12/04, 177.42 MB). It was impossible to finish the damn file transfer (even from LAN, because I downloaded the ZIP to my NAS with no problems - so my router is working correctly).

I'm now monitoring the change-log http://www.cmxlog.com/10.2/ovation/ waiting to see this WIFI bug addressed...
[Nook HD, HD+ Android Development] TheDannemand:
I hear you. I must say, though, that on my CM10.2 11/30, I have not experienced any other WiFi problems besides this YouTube issue. And that issue is most consistent at peak traffic hours (when my ISP, BrightHouse/TWC, is most challenged). Sometimes the issue isn't there at all. And as I reported, it was ALSO present on earlier versions of CM 10.2 as well as CM 10.1.3 final.

But I do believe it is possible that there is a WiFi issue that only manifests itself with certain combinations of routers and devices (like I mentioned some time ago about my problems with stock Nexus 4 on my TP-Link router). Between the different ISPs and different routers -- in addition to the different ROM versions, and a percentage of messed up installations -- I think that may explain why users here report different findings regarding WiFi performance and stability.

I have not had time to try with Carbon or Slim to see if they solve my YouTube issue.
[Nook HD, HD+ Android Development] wl08:
I am on 10.2 12/2, no issue at all, it might be your setup issue, try clean flash and restore data.
[Nook HD, HD+ Android Development] graysooner:
Wifi

I fully agree with the combinations of different devices problem. I have had zero WiFi problems. Running new nightlies as soon as they're available. 10.2 is not causing these problems all by itself.
[Nook HD, HD+ Android Development] starbright_:
Many users doesn't seem to care that Wifi Analyzer and tools like this doesn't work.

For me it is a clear indication that something in the wifi part (libs, API, whatever) is not work like it should be.

Unfortunatly I haven't seen a developer here in the forum since some time.

Does they left us?

My question what else (beside the missing host function) is not answered, so I guess everything else seems to satisfy people.

---------- Post added at 10:07 AM ---------- Previous post was at 10:04 AM ----------

I am estonished to read about

"wpan: Enable flag check for FM app"

or

"Camera: MDPI/HDPI assets for UI changes"
[Nook HD, HD+ Android Development] jpisini:
CM uses the same base for all the devices so we have camera code even though there is no camera.
[Nook HD, HD+ Android Development] Reed-Sternberg:
Disabling "allow purging of assets" in the developers options fixed it for me.
[Nook HD, HD+ Android Development] graysooner:
I meant to refer to the different routers being used with the same CM. Some people have WiFi problems, some don't. We all have HDs,but not all have the same emmc. So maybe it's a combination of some router(s) with some emmcs? Or maybe just some routers?
[Nook HD, HD+ Android Development] king200:
I'm not sure about the router being significant. I try mine at different locations and also with my phone as a hotspot. Connecting and getting an IP assigned doesn't seem to be the problem. Holding connection and maintaining throughput is the symptom. The mystery is why all devices using CM wouldn't have the same problem?
[Nook HD, HD+ Android Development] best1968:
Thanks for the tip, it was already disabled on mine so I guess that wasn't it.

I ended up doing full system and reinstalling most stuff (wasn't as bad as I thought - mostly because of TitaniumBackup)

So far so good though of course it's only been a couple of hours
[Nook HD, HD+ Android Development] graysooner:
Maybe we should compare emmcs? This HD+ is MBG4GA Rev. 06, no WiFi problems.

Just guessing, but there has to be something.

(Edit) Should have also said it's a 32g using trim
[Nook HD, HD+ Android Development] rholm:
Not sure of my emmc, but mine is a 32G and I generally am WiFi problem free. There have been just a few times when my connection looks up but I can't seem to access anything. I disable and reenable WiFi and everything is back to normal. This has happened maybe 3 or 4 times inthe last couple months.

I did have a period around Halloween when I was having a problem with random reboots. A wipe and reinstall of apps seems to have fixed it. I also switched from ADW to Nova, as many resets were when I was in the launcher.

I'm on 11/26 right now.

Rich

[Nook HD, HD+ Android Development] king200:
I don't think it is EMMC related. I tested HD, HD+32 (06) HD+16(06) and poor WiFi performance was present in all. Loading different rom on the same devices, helped make the WiFi performance normal. Examining the code mods made to CM for CarbonRom might be helpful. I did run with the only app loaded was Speedtest and verified result by going to Speakeasy.net with the browser. Trim and no trim didn't seem to make any difference.

Differences in performance of devices might be coming from the MACaddress assignment and/or the ip assignment. I don't know how to adjust settings of the HD to have a fixed IP. I know little about networking.

I neglected to test with only the HD accessing the WiFi and would appreciate if someone might try that experiment.
[Nook HD, HD+ Android Development] excalibar001:
Let me share my experiences with wifi. I never had any problems with early versions (September) of 10.2. In October, I started getting problems connecting to WiFi at my school but not at home. At home, it connects automatically and quietly but at school it would try long and hard but something would always go wrong during hand shaking or ip assignment phase. The October November versions of 10.2 were horrible. WiFi was very slow, dropped intermittently and I stopped taking my tablet to school.

The more recent versions are more tolerable. After turning on and off, it usually connects to my school WiFi. However I cannot watch YouTube as for some reason it stops buffering after 30 seconds. Can it be due to WiFi, anyone else having the same issues with YouTube?
[Nook HD, HD+ Android Development] insanespain:
I just got my Nook HD+ and my head hurts trying to sift through the threads and figure out exactly what I need to install this rom to emmc. I know i need the TWRP file, obviously the rom from CM, but what else? The way these threads are setup is about clear as mud. I've never had to make a bootable SD card before so this is new to me, and I am unable to find a clear instruction set for doing this.
[Nook HD, HD+ Android Development] leapinlar:
Go to the CM10.1 dummies guide, only substitute the CM10.2 zip and the right version of gapps. It is the best guide around.
[Nook HD, HD+ Android Development] Lavrentsii:
Not sure if this is the right place to ask, but what is the status of 4.4/CM11 for this device? Or are the dev efforts currently on how to fix the eMMC bricks before proceeding?
[Nook HD, HD+ Android Development] leapinlar:
I don't think anyone is working on a specific version for the HD/HD+ yet. I'm pretty sure verygreen is very tied up with his job right now. He is not even producing updates for CM10.2 right now. Be patient, it will come.
[Nook HD, HD+ Android Development] starbright_:
That's my impression too, we lost our maintainer at CM.

Regarding the Wifi issue: as some has it and others not - can it depend on the kind of access contol? WPA, WPA2, TKIP ....

I can remember that at the beginning I couldn't register my brandnew NOOK HD+, as it wasn't able to communicate with my router.

Not 100% sure, but I think I enabled different access methods, and after just on left it worked fine.

As for me, Wifi itself works, but all scanner tools (expect the build in) don't show any network.
[Nook HD, HD+ Android Development] leapinlar:
I don't think we lost him, he is just temporarily busy. That has happened a couple of times earlier and he always comes back. Besides, there are two, verygreen and hashcode.

I am attempting to compile cm-10.2 on my own. When I do the ./extract-files.sh, it complains that

several of the files don't exist. of course, this leads to problems later when compiling. Any sugestions?

I am running cm-10.1.3 (stable) currently.
[Nook HD, HD+ Android Development] SweetwaterBurns:
Download a version of 10.2 from cyanogenmod and either copy the needed binaries where they need to be using extract-files.sh as a reference or flash it and run the script.

Anyone had the problem where after charging to fullthe Nook is unresponsive and screen won't stay on? Occasionally I get a flicker of the screen but it won't stay so I have to do a hard reboot by holding the power button for 20 seconds. This has happened on various nightlies.
[Nook HD, HD+ Android Development] stanggt1313:
Do you have a case with a magnet to automatically turn the screen on and off by chance?

[Nook HD, HD+ Android Development] scififan68:
I noticed pages intermittently loading in the latest build, but then I looked in the wifi settings and the country code was set to Europe so I changed it to US and it seems to have gone away so far. Has anyone noticed that, or am I the only one to?

I also noticed the screen flickering on cm-10.2-20131208-NIGHTLY with no case on my Nook HD+, so I went back to the previous one and it went away.
[Nook HD, HD+ Android Development] TheDannemand:
Good catch. The ROM either defaults to Europe - or maybe that came from an earlier version and got carried over. I wonder if this could make an actual difference: Europe has 13 channels on the 2.4GHz band while US only has 11.
[Nook HD, HD+ Android Development] graysooner:
I had almost like a double or triple "jitter" load of pages, especially on this forum. Correcting the country code so far has fixed.
[Nook HD, HD+ Android Development] nikotime:
Actually I believe I do! Anyway to solve it other than stopping using the case?
[Nook HD, HD+ Android Development] stanggt1313:
Assuming you have the case open like a book in portrait, the magnet should be in the top left corner of the cover. i used a small razor blade to cut it out and glued the fabric back shut. I can't even tell it's gone. I'm not sure what case you have and how it would look after, but I can tell you I never had the problem after doing this. You might remove the nook from the case to confirm it's the issue, but I bet it is.

Wifi not connecting

Hi all,

I just gor my Nook HD+ and i have tried to install Cyanogen. The installation itself goes without a problem. And the rom works with out trouble besides one. For some reason Wi-Fi does not connect. It finds all the networks just find but once you try to connect the signal goes from very good to poor and it keeps saying connecting... after some time is just say disconnected and starts again. It does not matter if I set the network without any protection. And I have tried on 3 routers.

I have also tried changing router to only b/g network as well as changing wi-fi country code. And of course i tried multiple CM builds as well, both 10.1. and 10.2.

None of the above helped.

So if anyone has any advice what to try next it would be great.

Oh, and yes on stock it works with out a problem.
[Nook HD, HD+ Android Development] derschnelle:

You could try one of the latest nightlies, they work very well for me...

This won't help you, but I have a ton of apps that won't work at all on 10.2, it's just kinda garbage at this point really. I've gone back to 10.1.3 where things work fine.

What apps? All my apps work on 10.2.
[Nook HD, HD+ Android Development] laofan:
No issue here on cm10.2 12/9.

It would be easier for other to help if you could supply more information about version of cm 10.2 , your installation methods(wipe data/cache/system), what have you ever tried to solve this issue, etc.

[MENTION=377838]lakotnik[/MENTION] For wifi issue, maybe you could try wipe data/cache/factory reset, and go to wifi--->advance--->wifi region code--->choose U.S.

you might also try wifi optimization check/uncheck.

I have the same issue before but after the Nov 23 nightly I have never experience any wifi problem. If that still does not work, go back to 10/07 nightly, that is the one most people confirmed have better wifi connection.
[Nook HD, HD+ Android Development] artesea:
You have flashed the updated GAPPS for 10.2?
[Nook HD, HD+ Android Development] D000XXX:
Newest nightly working awesome btw :)

It's becoming faster and faster everyday
[Nook HD, HD+ Android Development] gamerka:
By any chance anyone knows why downgrading to 10.1.3 causing infinite boot?

I don't want to do a full wipe and I thought if it's not necessary when going 10.1 to 10.2 then it's not necessary other way around.
[Nook HD, HD+ Android Development] leapinlar:
Partly it is the gapps. Secondly, the CM10.2 apps know how to update from CM10.1 version to CM10.2, but CM10.1 apps know nothing about CM10.2 apps (system apps I am talking about).

But you can use Titanium Backup to back up the installed apps and restore them after a full wipe.

Ovation Kernel

I've compiled the ovation HD+ kernel with all of the latest goodies:

+Trim enabled

+Bluetooth tether fix (credit jisoo)

+DrMarble's 3x5 touchfuzz and pressure sensitivity

This will work on CM10.2 and Carbon, on builds from at least the last month.

---------------------

Also, I have the tablet UI patch for the dec 8 nightly. Later nightlies break the tabletUI autopatcher. Don't worry though, there's been no real relevant updates to for our tablet since.
[Nook HD, HD+ Android Development] razholio:
thanks for this. I'm gonna give it a try, though I'm not sure I'll actually make use of anything other than trim and I already use verygreen's trim kernel. I'm wondering if you know anything about the wifi issues that have plagued most of us on later 10.2 nightlies? Performance is quite good for me, but I'm plagued with the lack of wifi scanning. If i change my location, I can no longer see any SSID's, but can still connect to those that are saved in my settings. If I turn wifi off and on again, I get scanning back.
[Nook HD, HD+ Android Development] wolfhelm:
Does this build include BTLE (Bluetooth 4.0) support by chance?
[Nook HD, HD+ Android Development] danj88:
I'm sure this has been asked many times but I would like to be certain.

I have a Nook HD+ 16GB with the MAG2GA rev 6 eMMc chip running cm10.1 stable. Am I safe to install the latest CM 10.2 nightly?

If so, do I need to enable TRIM? I'm a bit confused even after reading the TRIM thread.

Thank you.
[Nook HD, HD+ Android Development] jamus28:
I don't use BT for anything but tethering, so I'm not sure. The hardware supports it, but I haven't checked if cm or verygreen activated it. I would go ahead and try it with your hardware setup.

I have that same chip. For most intents and purposes trim on cm10.2 is safe, faster, and better. Since the august patch, there have been no reported problems. The trim thread is a little too scary.
[Nook HD, HD+ Android Development] danj88:
Thank you. I presume I need to install the trim fix kernel to enable the feature?
[Nook HD, HD+ Android Development] jamus28:
Default kernel has it disabled, so any kernel with it enabled will... enable it.
[Nook HD, HD+ Android Development] chachi:
If only the trim kernel had OC built-in ...
[Nook HD, HD+ Android Development] wolfhelm:
I appreciate the response, from what I've read it has not been activated yet though I could be mistaken.

I dont have the BTLE device I purchased yet, it's backordered, so I wont know for a while, but I'm fairly sure that it is not enabled.
[Nook HD, HD+ Android Development] jamus28:
Judging from the way other devices have activated it. We may simply need to call the file from here:

https://github.com/CyanogenMod/android_device_bn_common/blob/cm-10.2/common.mk

PRODUCT_COPY_FILES += \

frameworks/native/data/etc/android.hardware.bluetooth_le.xml:system/etc/permissions/android.hardware.bluetooth_le.xml
[Nook HD, HD+ Android Development] wolfhelm:
Aye, I ran across similar information before for both CM10.1.2 and CM10.2 but I dont know how to implement it. I have to rely on my betters for such functions and hope to implement them on devices I root.

Map brightness to volume keys?

Is there a way to map the brightness adjustment to the volume keys?

Background:

It's hard to see something next (bright) day, if used this in the night before for reading.

A tablet of this size is usually not used just for listening music, where volume keys make sense.

And my videoplayers have more convenient on-screen settings for this.
[Nook HD, HD+ Android Development] SweetwaterBurns:
I don't believe you can without coding/compiling it yourself, but under the display settings you can set it so that swiping on the notification bar will adjust the brightness. I don't have my nook at the moment to tell you exactly where it is, but dig around and you should find it.

[Nook HD, HD+ Android Development] Reed-Sternberg:
It's dead silent here! and for a device with more than 60k CM installs:eek: (http://stats.cyanogenmod.com/), I guess this tablet deserves a little bit more love from the developers/maintainers.
[Nook HD, HD+ Android Development] TeutonJon78:
While I agree, there are 2 main factors there:

1) verygreen is really the only (official) developer and he's been busy with real life

2) 10.2 isn't really changing anymore, so what we've got is what we've got until there is a 11.0 build (or at least, an official one)

edit: #2 -- change "is" to "isn't"
[Nook HD, HD+ Android Development] rkeller62:
I personally don't expect to see an official CM 11.0 as the Nook HD/HD+ uses the TI OMAP SoC and I don't see there being hardware drivers for KitKat.
[Nook HD, HD+ Android Development] razholio:
I understand 1,but as for #2 I think there are still bugs to work on. At least some of us are still seeing the wifi scan bug, and I was hoping to see standby battery burn to settle down to 10.1.3 rates of 1%/5hrs instead of the max of 2hrs I see on 10.2. I have assumed that bug work would continue since no build has been tagged stable yet.

---------- Post added at 10:21 AM ---------- Previous post was at 10:16 AM ----------

That's what I was thinking, but there's a CM11 build for the nookHD+ already. I suspect the 3.0 ICS kernel that was used for 10.1 through 10.2 will be used for future CM builds until something critical in the kernel API changes and forces the use of a new kernel.

[Nook HD, HD+ Android Development] TeutonJon78:
Oh, I didn't say there weren't still bugs. :) Just that 10.2 as a base isn't changing that much, so each new build is basically the same, so no one has anything new to report/discuss. It's good ol' "status quo".

---------- Post added at 11:56 AM ---------- Previous post was at 11:51 AM ----------

Galaxy Nexus has official builds, and it's rocking the TI chip.

We just need a developer to get it all spify and updated to CM standards then I assume we would be back on the train.

So, I was having issues where the nook was basically unusable while installing anything from the market or downloading to the internal storage, paired with absolutely attrocious I/O speeds in benchmarks (110 or so in antutu). It was pretty frustrating, and I was ready to try just aabout anything to speed things up - the nook just shouldn't be this slow. After some researchI realized all of our ex4 partitions were journaled, so I poked around in TWRP and disabled journaling. Wow, what a differenence it made, it's like a completely different device. Antutu now shows I/Os in the mid 600's and I can feel the difference.

For anyone with similar issues who feels adventurous, I'd say give it a go. I'm in love with my nook again. Anyone else give this a shot before?
