:) I think I am about to lose my virginity (too completely whiping nook)

I read a couple days back that this was only available for internal flash (honeycomb) but I see that it is also on SD. Now out of all builds what is good all the way around. Which is the most popular for stability and now that you guys are talking watching videos and such. I purchased an 8gig just for flashing or running roms on the nook now. Basically lol I have a problem (flashing thanks to wm days) and I just don't wanna be like that (I'm lying). Just looking for the a stable release and which way is preferred on system or on SD.

Just flashed the latest kernal you posted on 2/23 to the cm7. Everything seems to be working fine and touch accuracy seems to have improved. Thank you Dalingrin.

Feature request/wish:
- iptables and netfilter support......please

Nooking with Encore

Damn, meant to include netfilter a long time ago. I'll try to push new kernels again tonight...

Dalingrin - I know you are SWAMPED, so i hate asking, but if you are making a new one, can i ask for one more small thing? Since the Kernel now support an overclock, but is default at stock speeds, do you think you can add in some of the faster clocks like 1150 and 1200?

Thank you again for all your kickass work. The NC community really owes you, Fattire, and others a huge debt of gratitude for all your efforts. :)

there was a 1200 kernel posted in the thread somewhere in the middle if you search.

Yeah, and there have been several updates and the release of CM7 since then. The old 1200 kernel is outdated. I'd like to see the option to bump it up added in to the current kernels as well. It's not near as important as the other work that's going on(DSP!), so no big push or anything, especially because not everyone's nook likes those speeds, but if it's not a big deal, it'd be nifty.

Exactly. I won't be hurt at all if it is a big deal, since frankly, i would rather see more updated kernels (or even the .32 kernel); but if he is kind enough to have time, it can't hurt to ask. :)

Kernel not sticking

K, so I am using nookie froyo and tried to flash 2/23 froyo kernel, wiped cache and dalvik cache. Installation said successfully completed and booted fine. When I look at about phone and setcpu, I see I still have the old kernel. It didn't take. I'm not sure what happened. I'd like to be able to use one of the OC kernels. Thanks

What is your max speed available in SetCPU?

By default the omap3621 only uses 3 OPPs(think clock steps) and I've extended that to 5. Unfortunately the omap36xx generation can only handle a max of 5 OPPs. So, I'll need to make a separate kernel for >1.1ghz.

I'll probably make a kernel dedicated to >1100mhz with 300mhz, 600mhz, 800mhz, 1150mhz, and 1190mhz OPPs.
No promises that I'll get that done tonight though.

Verify you used the correct update.zip for either eMMC or SD card.
I need to flesh out the update.zip for error handling at some point.

Not a worry - if i see it, cool, if not, no biggie. Thanks for the update though. :)

I did use the correct zip and still a no-go.

Having an issue with retainig my oc' in CM7/Phiremod. I have Dalingrin's Froyo/CM7 eMMC kernel flashed. In CM7 under CyanogenMod Settings I can choose 1000/1100 and everything runs fine, however when I reboot it does not retain the oc'. It reverts back to 800mhz default. This is with "Set on Boot" Checked or unchecked.

Can anyone comment on this? Thanks guys. If this is better suited for the CM7 thread let me know.

sorry guys but I need help I can't get flash to work right on sd care

I used the 8gig clockwork in win image, added the cm-encore-full.zip and update-HC-dalingrin-OC-sdcard-022311 and I can't get it to run after installing the cm-encore-full by itself or with the update-HC

    Using this kernel is at your own risk. Before flashing make backups!!!

    Overview
    -In addition to the general CPU overclock the DSP and possibly the L3 bus are overclocked to levels comparable to other higher end OMAP3 SOCs. This should result in a minor speed up in video decoding among other things. Occip pointed out that the L3 bus is set in the boatloader and kernel values are ignored. I still need to investigate this.
    I feel comfortable with the overvolt used in these kernels for a few reasons. Omap cpus automatically reduce voltage based on load and stability. The voltage gating in omap processors is very advanced. Absolute voltages set in the kernel are only a maximum for a given clock rate. The cpu should seldom reach the defined maximum. In addition the highest overvolt used is very small ~0.05v.​

    Common Features for 2.6.32 builds
    -As of 06/09/11 the CPU clock can be customized via this app: http://forum.xda-developers.com/showthread.php?t=1104039
    -Overclockable to 1200mhz and 1100mhz. Must be set with an app like SetCPU unless running CM7. CM7 has overclocking under Cyanogenmod settings. DO NOT use SetCPU profiles with CM7.
    -****Small overvolt**** compared to the stock 3621 specs. This is running at the same voltage as the omap3630 which is very similar to our CPU.
    -1.2ghz is overvolted slightly more compared to 1.1ghz. Resultant voltage is dependent on your particular hardware. It will attempt to dynamically scale to keep stability.
    -Available clock speeds: 300mhz, 600mhz, 800mhz, 1100mhz, 1200mhz
    -Partial fix for strange touchscreen edge behavior brought to you by deeper-blue.
    -Smartass CPU governor. Very similar to the Interactive governor found in my 2.6.29 kernel but with a built in SetCPU profile-like functionality. CPU clock speed is limited to 3-600mhz when the screen is off.
    -Various performance tweaks.​


    Kernel Downloads


    * This kernel is included in CM7 starting with nightly 132 and will be CM 7.1 stable. There is no need to flash a separate kernel unless you are running Stock Froyo 1.2.
    * 2.6.29 releases are discontinued and no longer supported. They will remain hosted for those that might need them.
    * There are separate builds for CM7 and stock 1.2 Froyo
    * 2.6.32 CM7 builds currently do not work with the stable CM7 builds until CM7.1. You need to use CM nightlies until 7.1 is released.

    * All 2.6.32 kernels require an updated u-boot from B&N 1.2 Froyo. If your Nook has "Read Forever" or a green Cyanogenmod logo on the screen when you boot then you have the latest version. If it says something else then you need to update.

    [1/23/11] - 1.1ghz kernel added
    -This kernel is stable on my Nook after 10 Quadrant runs. Still boots everytime as well.
    -Renamed the 1ghz kernel to match new 1.1ghz kernel

    [1/23/11] - New 1ghz kernel added
    -This kernel is an experiment it uses more Omap3630 settings than the previous kernel which seems to make it stable for me.
    -I don't expect this kernel will be stable for everyone but for those that could get
    950mhz to work, you may be able to get this 1ghz kernel working.
    -Only short term stability testing so far. YMMV


    Install Instructions:
    All kernels are CWM flashable.
    If not using CWM, unzip the contents of the update and push uImage onto /boot partition. Then you will need to copy the system folder.
    Code:
    if flashing to sdcard:
         adb shell mount -t vfat /dev/block/mmcblk1p1 /emmc
         adb push uImage /emmc/uImage
         adb remount
         adb push system /system
    
    if flashing internal eMMC
         adb shell mount -t vfat /dev/block/mmcblk0p1 /emmc
         adb push uImage /emmc/uImage
         adb remount
         adb push system /system
    
    Reboot Nook!

    If you have problems with force closing apps or poor performance, clear the dalvik cache and regular cache.
    DO NOT use the Rom Manager option to wipe data and cache. You do not want to wipe data. Just boot into CWR
    and wipe cache, then under advanced wipe dalvik cache.
    Note that the first boot after clearing the caches will take longer than normal.

    Yes....This color is hideous.

    well, its been about 3hrs since I log out of latitude and Im happy to report that my nook has been deep sleeping all this time. according to cpu spy, deep sleep 95% and the 5% was shared between 300 and 600 :D

    I think this is the trick to long deep sleep. Im going to turn on live wallpaper and see what happens. its going to be interesting to see how it goes over night. so far so good.

    Just to add: I've never had problems with deep sleep and I've also never signed into latitude.


    About PBD:
    Its on my to-do list but it isn't at the top yet =(
    It seems to have gotten better for most folks who have been rebooting regularly so I'm working on other things for now.

    Things on my to-do list:
    -Merge OMAP SoC optimizations into the CM7 framework(this helps us and lays the foundation for OMAP4 support in CM7)
    -Figure out why our Wifi driver sucks and is causing SODs for some people
    -Media optimizations, including Flash hw overlay support and perhaps 720p DSP decoding(media optimizations are dependent on the OMAP SoC optimizations first)
    -Merge OC kernel into CM7
    -Look into PBD again
    ...etc

    I will no longer be releasing this kernel separately from CM7. It will be merged into CM7 as the default kernel. I will keep this thread alive for Stock 1.2 users.

    By default CM7 will use a 32 bit framebuffer as it always has. If you prefer 16 bit for performance, like what is in this OC kernel, then you will be able to switch it via Nook Color Tweaks.

    Once this update is merged it will contain a few other changes. The biggest change other than the kernel is the GPU drivers and libraries. These have been updated to a much newer and supposedly faster release. The wifi driver has also been updated.

    In a separate commit I will also be moving us back to lcd density 160. I've stuck with 161 for a long time now due to a bug in the Android Market. Fortunately, the new Market has fixed the issue and we can now move back to a 160. This will allow more apps to better scale to our display.

    I honestly don't know what else can be done to improve Bluetooth. As of now we've backported 2.6.35+ bluetooth drivers and software to use on the Nook. Most of the important parts are controlled by a closed source proprietary firmware. Not much I do there.

    For those that use Bluetooth and are comfortable with Android and Linux, you could try different bluetooth firmware/script. This is a .bts file.

    I want to stress that last point.

    When the kernel went from 2.6.29 to 2.6.32, the bluetooth driver was completely re-implemented (that is, bluetooth was enabled, not once, but two totally different ways for you people..) using a backport of the 2.6.35 driver. So rather than using a simple bluetooth hci driver, CM7.1 uses a "shared transport" driver-- a newer, fresher way of doing things that requires a userspace daemon running ("uim") that interfaces with its counterpart in the kernel("kim") which manages traffic coming from 2ndary bluetooth, FM radio, and (if nook had it) GPS drivers-- because all three can be on one low-cost wireless chip. Which is pretty amazing actually. So since they're sharing the same chip, they need a "traffic cop" to communicate to the rest of the computer, and that's what the kim (kernel init manager) /uimd (user init manager daemon?) shared transport is about.

    Now in the nook's case, there is no antenna for the FM radio (until someone adds one), and no GPS hardware at all. The nook has a WL1271 in case anyone cares. But just as the wifi (which is also on that chip) has its own firmware that is installed at boot via "wlan_loader" (see /init.encore.rc), the bluetooth chip does too-- and basically it's initialized via a "bts" (bluetooth script I think) file provided by Texas Instruments that is run at boot by kim at uim's request, if I remember correctly.

    To quote myself:

    There are several versions of TI's bluetooth initialization script, called the "bts" script. You can get them here:

    https://gforge.ti.com/gf/project/wilink_drivers/

    The .bts files (such as TIInit_7.2.31.bts) may be placed in:

    /system/etc/firmware

    and will automatically be loaded when needed. Try different versions and experiment to see if some work better others. (Watch the log and dmesg to verify that the bts script is running properly)

    These .bts files are custom-written by TI to initialize the bluetooth hardware, and I think that would include setting up power levels and stuff that might be affecting signal strength and all the complaints everyone has. As there are several versions of this file (oddly many sharing the same name), it is still up to *you* to try them all and see which works best for the encore. Who knows, you may stumble onto one that extends the signal by a mile. You can even bat your eyes and petition TI to whip up one custom for the nook. So go on, be a hero.

    Anyway, that's where things stand with that. TMI? Well, you asked.

    One last thing, from Dalingrin's list:

    -Merge OMAP SoC optimizations into the CM7 framework(this helps us and lays the foundation for OMAP4 support in CM7)

    I really want to stress for everyone how much work this is, and that everyone owes Dal some beers or something. I know how much work this is because I went through it once several months back (way before .32 was ported, so the tree went stale and it all ended up being worthless), and it was a monster of a project. But it will be many hours well spent-- the Nook COLOR is based on the OMAP3 system (OMAP3621 if you care)-- but when Dal gets this done and accepted into CM7, it will make the CM7 framework OMAP4-friendly for new, as-yet-unknown devices in the years to come...

    So scroll back up, and thank him again.
