Thanks for the reply! yea I left the tab plugged into the wall overnight and tried to odin first thing this morning and get the same result.
[Galaxy Tab  Android Development] tpike:
can odin see your device when connected to usb?
[Galaxy Tab  Android Development] monkeefied:
yes it can
[Galaxy Tab  Android Development] tpike:
from what ive done in the past is odin or heimdall the stock files. its kinda scary dont get me wrong, but as long as odin is seeing your device youre not toast. i had it where the drivers quit working and i freaked out thinking i had no odin or heimdall, but using the usb driver installer from samsung i got it all working. it happens when youre using so many kernels and roms that might not exactly fit together. keep youre head up!!
[Galaxy Tab  Android Development] monkeefied:
ok i got it, I think it was having an issue charging in this mode, I was able to try it again and I had Odin set up ahead of time and when the screen was on for a while I quickly unplugged from the wall and into the laptop and it finally went whew!
[Galaxy Tab  Android Development] tennandcoz1:
Thank you brother.
[Galaxy Tab  Android Development] tennandcoz1:
Thanks for that brother.and you are 100% right.iam thinking of themeing or trying to lol.not real good with the computers,so I dont know how to begin.i will try.tpike thank you
[Galaxy Tab  Android Development] Rodderik:
so you got it all fixed up?
[Galaxy Tab  Android Development] monkeefied:
yup runnin smooth as silk thanks!
[Galaxy Tab  Android Development] frickinjerms:
i remember when i first saw the emergency download screen when i tried to get the leaked gb on my tab a couple months ago haha at first i thought it was just the gingerbread download mode buuuut realized quickly that it wasn't when i couldnt get anywhere else haha it let me odin back to the old froyo and continue my relatively frivolous flashing haha good times good times
[Galaxy Tab  Android Development] Rodderik:
spectacular
[Galaxy Tab  Android Development] solinar:
Hey, big thanks for this.

Just FYI I spent hours trying to flash this, getting boot loops, soft bricks, etc, until I finally decided to swap cables.

Don't be a dumb-ass like me. Make sure you use your Samsung branded data cable for any flashes you do.
[Galaxy Tab  Android Development] Rodderik:
working on some custom kernel love now :)

BLN, voodoo sound 10, and jhash3 done already
[Galaxy Tab  Android Development] jocala:
Just as an fyi, your busybox doesn't have vi enabled...
[Galaxy Tab  Android Development] Rodderik:
you're right it doesn't...busybox is built into the cwm binary to save space in the kernel and it doesn't look like the latest cm7 version of busybox that is compiled in has vi enabled...you can however install busybox from the market into /system/xbin/ and it should give you access to vi
[Galaxy Tab  Android Development] jocala:
I just compiled it last night. You solved a mystery for me though. I was wondering why busybox was symlinked off recovery, now I know :)
[Galaxy Tab  Android Development] Rodderik:
yeah it shaves about a 700k to a meg off the kernel size (so we don't go over our 7MB partition size)...it isn't 100% like the stand alone binary but the features it lacks versus the space it saves is worth it...it allows us to put superuser and stuff like that in the kernel to keep root, recovery, and all that self contained in the kernel
[Galaxy Tab  Android Development] jocala:
That's a clever use of space. They did leave the symlink in for vi though, so perhaps they'll correct the oversight.
[Galaxy Tab  Android Development] Rodderik:
the symlink is my fault...one of the issues with the cm7 busybox that gets compiled in is that it doesn't do --install like the full binary does...sorry i didn't test every symlink :P

how about an overclock kernel with brazilianwax scheduler. 1.2 is definitely do-able - 1.3 works pretty stable if temps are cool (ie not at pool on hottest summer day or left in car) - but i heard of 1.4 to 1.6ghz with more voltage. tegrak can overclock this cpu and over/undervolt at each speed step - which is nice but costs money. if we could enable options for voltage and extra mhz but default to 1.0ghz we can use free tools to find the best speed. 1.3 makes a HUGE difference with dolphin browsing modern html5/flash pages.

htc flyer brazilianwax 1.7ghz

ram 545 int 1107 float 493 2d 267 3d 835 db 360 sdw 65 sdread 190 total 3862

galaxy tab 7 performance 1.3ghz =

ram 242 int 462 float 117 2d 295 3d 1004 db 210 sdw 37 sdread 86 total 2453

so stock speed is pretty weaksauce :(
[Galaxy Tab  Android Development] Rodderik:
im already one step ahead of you..i have 1.2ghz booting and running like a top... i have 1.3 mostly stable and i am aiming for 1.4...i will get it working then i'll see about pushing it a little further or not....it's definately going to need some better governors

Do I need to Root first?

Do I need to Root first to flash any Roms on the first page or can I do it with out been rooted?
[Galaxy Tab  Android Development] Rodderik:
to install the stock deodexed rom you will need to odin the prerooted/cwm kernel in order to flash it
[Galaxy Tab  Android Development] mrkrad:
you rock! i think 1.3 requires more voltage on one of mine it destabilizes. 1.2 works fine on both with no voltage. suprised at how little overclock we're getting - i wonder if that just requires more voltage - usually these buggers can do 25%-33% easy - the brazilianwax is nice how it pops to max resp when coming out of sleep so you get a nice turbo boost then it creeps back down - i don't really play games but if i load up izismile or a complex html5 page you need juju really quick then settle back down quickly and ramp back up quickly - mostly for the app that has the screen (Browser,app market,etc). it would be interesting if you could renice background tasks scripts like checking for an update - not sure if this variant of *nix has that already or what. ;) good job

Dropbear ssh addon

Dropbear is a software package written by Matt Johnston that provides a Secure Shell-compatible server and client. It's designed for environments with low memory and processor resources, such as embedded systems. It allows you to remotely connect to other systems's consoles and to copy files to and from other system via the terminal. It also allows you to connect to your tablet from a host machine and copy files to and from it, much like adb. Windows users use a tool called PuTTY , *nix users connect with ssh/scp.

Version .052 of Dropbear has been compiled and patched for Rodderik's ROM and Android.

This archive also includes the rsync program which allows *nix systems (and Windows systems with cygwin installed ) to remotely sync files/directories between a host and your tablet.

I use this suite of programs to monitor programs on my torrent server from my tablet, copy files between the tab & my web server, general maintenance type stuff. Rsync comes in handy to keep media files up to sync (ebooks, mp3s, etc) from my central media server to the family phones and tabs.

Included programs: dropbear,dropbearkey,ssh,scp & rsync. ssh and scp copied from cm7.

http://jocala.com/stock-ef17-dropbear.01.zip

Install with cwm.
[Galaxy Tab  Android Development] Rodderik:
thanks ill mirror it and add a link in the addons section in just a little while
[Galaxy Tab  Android Development] jocala:
Thank you for this open, easy to modify platform! I hope some other geek finds some use from dropbear. I use it every day.

[Galaxy Tab  Android Development] mrkrad:
can you share the app? tegrak does it with an app for voltage at each level step and governor settings. or are you rolling a complete kernel?
[Galaxy Tab  Android Development] Rodderik:
it's a full kernel...i don't like to use apps to do stuff the kernel should be doing when we have source code...you use xan's voltage control from the market to control the freqs and overclock/undervolts

Testing Rodderik's overclocked kernel

Using Rodderik's stock rom and overclocked kernel, running on EXT4, I get a Quadrant score of 3014!

I used the app called Voltage Control to set the cpu to performance mode, and set the minimum and maximum CPU speed to 1400MHz.

Here is a screenshot of it:

Awesome work, Rodderik! Can't wait for more from you.
[Galaxy Tab  Android Development] Rodderik:
updated stock deodexed rom to v3:

fixed ScreenCaptureService.apk (holding back and hitting power to take a screenshot)
[Galaxy Tab  Android Development] Rodderik:
spectacular...i hope to release the kernel monday or tuesday (in a separate thread) so we can keep this one for the stock stuff...i just needed some testers :)
[Galaxy Tab  Android Development] mrkrad:
nice - you are a well respected developer :) will definitely donate for a nice clean stable kernel with mojo!
[Galaxy Tab  Android Development] jocala:
I've never overclocked. What kind of effect does it have on battery life?
[Galaxy Tab  Android Development] mrkrad:
governors (setcpu,no frills,tegrak) let you select the voltage steps and profiles - so you can say powersave and it may undervolt and limit to 1ghz and sloooowly ramp up - giving you more time - performance means lock at full speed always and burn the battery up for times you need solid performance. Brazilianwax is a hybrid where it ramps FAST out of sleep then ramps fast when you use the device.

so it's like a gas pedal - you press it down alot - it goes down. you don't press it - you get good mileage. with powersave - i get far better battery life (GPS off) - and for light browsing(no flash video) it is great. Brazilianwax on my flyer @ 1.7 - i get the same exact battery life as the stock 1.5ghz but its snappier.

I do not have this rom but the other ways to overclock seem 50/50 one does 1.3ghz and another does 1.2ghz - stable. I think they do not address the voltage correctly - which is part of the tuning process - if you don't get 1.4ghz - bump the voltage then try again. if fail (run a benchmark with video a few times to test) then just back off to 1.3(or 1.2) and try again. 1.2ghz no sweat. 20% faster with a good scheduler feels like 30-40% faster when cruising websites with no battery penalty.

Heat is a byproduct of more voltage and faster speed - your battery is affected by heat so don't take it out at the beach on performance 1.4ghz and expect it to not thermal shutdown. heck my ipad does that and it is 100% stock
[Galaxy Tab  Android Development] tpike:
I keep my epic at 1.4 and i've had my tab at 1.3 and I don't see any change on battery. Fancy widgets set to update automatically every half hour kills my tab, but 1.3 I still get 48 hours.
[Galaxy Tab  Android Development] jocala:
Very informative, thanks for the info folks!
[Galaxy Tab  Android Development] tpike:
wow...some good things in the works!!!!
[Galaxy Tab  Android Development] mrkrad:
Let's be blunt: What's an average donation? I know you are doing something i want - good stable overclock rom - and will donate when you release - but honestly i have no idea (i do tip well) - maybe you can give us insight into how much is average, how much is above average?

If you tell us the low, middle, and high average we can tip/donate accordingly - i have great respect for someone that works hard on roms and uses the money for good use - as a coder myself i would be appalled if someone was taking other people's work and using that money to dope up, hypothetically speaking.

I'd rather save up and make one good appreciative donation now and then than send you a smaller amount and make you feel your work is not truly appreciated if you know what i mean?
[Galaxy Tab  Android Development] Rodderik:
I gotta tweak on the 1.4ghz setup but I'm close to releasing it I believe. tpike is working on a custom rom and I've given him permission to use the 1.2ghz kernel...can't wait to see what he has done with the rom.

To answer your question let me say first that donations are not required but I greatly appreciate them. Maintaining a popular kernel for the Epic I got donations maybe 2-4 times a month that typically range from 1 dollar to 20 dollars. A couple of times I have gotten $50 donations from my loyal testers. But overall not much money from donations. Rom developers get a little more ppl donating. But there is my take on donations in case anyone else was curious.
[Galaxy Tab  Android Development] Rodderik:
just an update...haven't had time to mess with the 1.4ghz kernel lately....i had to find new hosting and migrate all my websites that i run to a new server and helping some ppl on an epic kernel but i hope to get back on the kernel by the end of the week or beginning of next week. saturday is opening day of deer season so you know i won't be around here for the weekend (like usual) :D
[Galaxy Tab  Android Development] jocala:
Good luck on the hunt! I don't hunt any more but back in the stone age I used a 40Lb recurve and a 30.30 Winchester.

BTW, I got my uclibc toolchain working. I can compile a C 'hello world' program for the tab that is only 17K! That may not mean a lot to most, but I'm amazed :)

I ended up using a program called crosstool-ng to generate my toolchain. I'm unsure if the uclibc toolchain it built is suitable for a kernel compile, but I intend to check it out :)

Can someone give me utf8-nls.ko for cifs
[Galaxy Tab  Android Development] jocala:
I have nls_utf8.ko attached, compiled from Rodderik's kernel source. Hope this helps.
[Galaxy Tab  Android Development] Rodderik:
are you using the kernel in the OP?

config NLS_UTF8

tristate "NLS UTF-8"

help

If you want to display filenames with native language characters

from the Microsoft FAT file system family or from JOLIET CD-ROMs

correctly on the screen, you need to include the appropriate

input/output character sets. Say Y here for the UTF-8 encoding of

the Unicode/ISO9646 universal character set.

CONFIG_NLS_UTF8=y

if that is what you are looking for it is compiled into the kernel already

to root gingerbread all you have to do is odin the kernel in the OP

I'm sure this method is equally as fast. Odin one file...done.
[Galaxy Tab  Android Development] jocala:
I think rjumawan may be trolling :)

There is no one-click available for our tab on GB. There are a couple of GB ROMs that offer root, but nothing open like Rodderik's kernel. If there is a root exploit, give me a link, "google this" doesn't cut it.
[Galaxy Tab  Android Development] rjumawan:
I found this from samsung galaxy tab forum.Why on earth would i need to lie.Shoot you google the above and its the first one thay pops up that I used.investigate before you talk.to many people on here like that.maybe you all need to opem your own forum. .

[Galaxy Tab  Android Development] jocala:
LOL!

Rjumawan, I do apologize for thinking you a troll.
[Galaxy Tab  Android Development] Rodderik:
ah that points to the old method to root...it's much easier and a lot easier on bandwidth to use the pre rooted kernel in this thread now (which is also on my site as well btw)

Thanks for the link apparently I did not use the right keywords.
[Galaxy Tab  Android Development] jocala:
I never found a HOWTO for ROM creation. For my first, I downloaded a ROM for the Epic4G, dumped it to my hard drive and started to explore. In very broad strokes:

Step one will be to have a linux environment to work in for either ROM or kernel development. If you're currently running Windows or OS X, setting up a virtual machine will be your best bet. Check out VirtualBox and set up a Linux image for your development chores.

Dump Rod's ROM to the hard drive of this virtual machine. This will be your playground.

What you'll have is a clone of the GTs /system directory, and this is where you do the majority of your tweaking for your ROM.

Starting out with a stock ROM like Rod's is the way to go. Once you've made your changes in this /system directory, you recompress it and flash it to your tab via clockwork mod or odin.

Like I said, broad strokes here. Get a dev system set up and start to explore Rod's ROM. If you ask questions here I'm sure you'll get useful answers.

Kernel development is another ball of wax. You'll have the majority of what you need once you set up your dev system and download Rod's stock rooted kernel, but you'll need to add a few software components required for kernel compiles and learn how to make changes to the kernel compilation instructions (using a kernel facility called menuconfig). Google will be your friend here, but it's not a terribly complex procedure. Once you can recompile the stock kernel, you can move on to making changes to it.

Dive in :)
