Yeah I've seen documentation saying the Galaxy S phones have 4Gb of RAM. 1Gb of which is OneDRAM and 3Gb is LPDDR (Idk version). Now, tell us why ODROID and the block diagram can do 1080p and we can't.

EDIT:
[Epic 4G General] Electrofreak:
I just pulled my information from some raw data about the Intel GMA500 (which is an SGX540 disguised as Intel) running at 200 MHz. I would assume the 4.2 GB/s bandwidth needed assumes TBDR is being used.

It's a shaky line of reasoning though. Wish I had some more hard data on the SGX540, and more specifically, the clock rate it runs at in the Epic.

Yeah, I could swear I've seen those numbers somewhere but I can't for the life of me find it.

As for the 1080p, that's a good catch; interesting. And, now that I look closer, WiFi doesn't have N support, though I suppose it's possible they used a different WiFi chip.
[Epic 4G General] Electrofreak:
delete, double post.
[Epic 4G General] gTen:
Interesting...I guess it makes sense somewhat...though with that much processing why would they then set an FPS limit? is it suppose to be their way of saving energy?

As for 1080p..we have specifications for it..If i were to guess we just don't have the proper drivers...video decoding is done via the ARM Neon..so if anything 1080p would play slow..but it doesn't play at all...so its either locked out intentionally..or the driver is not configured to...I mean it can handle 720p at High@L5.1...no reason why it can't handle 1080p at lower settings...
[Epic 4G General] hayabusa1300cc:
Wow.. My brains are like oh my gawds!

Interesting tho
[Epic 4G General] arashed31:
Another thing. If you look at the Bluetooth certification site you'll see the Samsung Epic is certified for Bluetooth 3.0. Even though the chip in there is a Broadcomm chip that only supports Wireless N and Bluetooth 3.0.

Video decoding is on the processor? WHAT. THE. HELL. SAMSUNG.
[Epic 4G General] tmuka:
Sounds like you did your homework, i'll buy it. Thanks for sharing. I'll take the fast vid over ram too :)
[Epic 4G General] Electrofreak:
Homework, yes... but I'd really like to see an ARM engineer affirm it.

Yeah, I just actually took a look at the S5PC110 User Manual and sure enough, 1080p encoding / decoding at 30 FPS is showing supported on the block diagram:

"1080p 30 fps MFC

Codec H.263/H.264/MPEG4

Decoder MPEG2/VC-1/Divx"

But then, directly below the block diagram, the following is shown:

"Multi Format Codec provides encoding and decoding of MPEG-4/H.263/H.264 up to 720p@30fps and

decoding of MPEG-2/VC1/Divx video up to 720p@30 fps"

That's an odd discrepancy, particularly for an official Samsung processor owner's manual.

Also worth mentioning is that that manual makes no mention of OneDRAM in the memory subsystem breakdown where OneNAND, LPDDR1, LPDDR2, and DDR2 support are outlined, however, it's clearly listed as a supported memory type in the block diagram, and later throughout the manual. Hmm.
[G Tablet General] Orz-Orz:
well not sure what I did but after certain point, if I shut down Gtab, even I push the power button, nothing happens.

but if I do NVflash, it come back.. but if I shutdown after that, I dies again...

I tried to do factory reset but when it shut down Gtab, Gtab dies , so not do anything...

How can I fix this?
[G Tablet General] fletch33:
it is a common problem and i suffer from it as well. i have tested this with different roms and letting the gTab sleep in different fashions as well as nvflash and mine never works.

i thought it was kernel related but much testing has made me believe that it is hardware related somehow.

i have other people i know that never have this problem and so i am exchanging mine on Monday.
[G Tablet General] necromonger89:
It would be helpful if you explained exactly what is going on. It seems as though you have low battery power according to what you have described.

I suffered a boot loop on my first attempt to flash my G Tab. I didn't know how to fix it so I returned that one. BTW I tried Nvflash, flashing back to vanilla and nothing happened. What ended up solving my problem when it happened again on my other tablet I quickly solved it by partitioning to default 2048 with 256 swap. Since then I have not had a boot loop issue. Now I don't know if what you are describing is a boot loop or not.

A boot loop is when you turn it on and it goes from the Viewsonic birds startup screen to the G Tablet logo and back to the birds again for infinity. Is that what you mean?
[G Tablet General] fletch33:
my problem is that no matter how the gTab goes to sleep it will not wake up again with the power button. the power button just fires it up again instead of waking it up. no roms or stock nvflash retore solves it.
[G Tablet General] Orz-Orz:
figured out by myself..
[G Tablet General] Orz-Orz:
well it was totally my fault..

i downloaded the wrong ver of NVflash file from that dropbox site.

once I NVflash with the correct version, everything is fine now..

Thanks for your comments!:p
[G Tablet General] necromonger89:
I would attempt to reflash it, wipe data, wipe partition cache if any, partition sd card if you haven't partitioned and start again(reboot). I am no expert on this matter, from experience this is what helped me out. It could be an app or something that did not install correctly or is conflicting. I had some apps in TnT 2.4 that conflicted and would kill or turn off my tablet. Sufficient to say, I started new on Vegan and slowly restored the apps I knew worked well on TnT 2.4.

Hope this helps in any way possible. If not, return it asap if you are still covered. (I would put it on a boot loop and remove clockworkmod, say that it was a problem with the OS or something.) This is how I was able to avoid the 15% restocking fee at Sears. Either that or the guy who exchanged it for me was too nice or was new.

Look here.

The cpu for the nexus one is insane. I don't care about I/O or anything else but cpu. Is there any way a vibrant (or any other galaxy phone) to match the nexus one in cpu speed? Is it possible without overclocking? If so then how can it be done?
[Vibrant Q&A, Help & Troubleshooting] mdof1337:
Contrary to quadrant scores (Which aren't everything btw) the 1GHz Galaxy S Hummingbird is a much better processor than the first gen 1GHz Snapdragon that's in the Nexus One. Android 2.2 and the subsequent JIT compiler in it were coded specifically for the Snapdragon, therefore that processor runs the best in 2.2. Now the newest Nexus phone, the Nexus S, has Android 2.3, and Gingerbread and is coded similarly for the Hummingbird. Basically, the Hummingbird is the superior processor, and that is demonstrated in 2.3.

It looks like JIT can still use some improvement. 2.3 running on nexus one is still 40+ mflops in linpack vs 15 on nexus s.

[Vibrant Q&A, Help & Troubleshooting] h1a8:
So the quandrant scores are false?

So what about the 2.2 custom roms we have for the vibrant? Do they have a JIT compiler as well? Why don't they give the vibrant anywhere close to the Nexus one's (which has an inferior processor) cpu speed?

One sure test for the Nexus one is for someone to download and install Droidfish chess program from the market (it's free) and hit analyze. On the vibrant Droidfish reachs 100,000 nps after 50 seconds. I'm curious to what the Nexus one will reach here.
[Vibrant Q&A, Help & Troubleshooting] SamsungVibrant:
Concerning your statement in bold, you will get different answers depending on who you ask. Some people do not believe in Quadrant or any benchmarking, others think they are very accurate and representative of real world results.

I personally believe Quadrant is an excellent benchmarking tool, it is accurate, and representative of real world results. That is just my opinion, and someone else for sure will disagree.

Not anymore. New linpacks will max at. 15. Just update and test. You'll see.:-)
[Gen8 General] jerdog:
Given the law about releasing the source for their OS implementation, I.e. kernel and hardware drivers, when do we expect to have the 2.1 source, giving us a feel for the 2.2 implementation? Should have released the 2.1 by now for the 70 and 101....

EDIT: Looks like Android 2.2.1 (Firmware 2.0.54) was released Nov 30, 2010 - so we should expect to see the source for it by the end of this year.

EDIT: Looks like the source has been released - http://www.archos.com/support/download/software/sources/gen8-gpl-froyo.tgz

Now we need someone with good Linux abilities to start helping us compile a custom kernel.....

no custom kernel till we get rooted for the phone...once we get rooted we can do watever to it..im gonna have me a ball with this once we do...lmao
[Gen8 General] jerdog:
So does the SDE not look attractive? We have root that way and can do kernels and such....

But I would rather have FULL root (NAND unlocked like we do with HTC phones) enabling us to fully take over the device - instead of essentially a dual boot environment that leaves the stock build on the device and takes up space....

There seem to be some people who think we can't unlock NAND - and don't see why we would want to.

[Gen8 General] txtmikhail:
i dont know much about the SDE but i know i dont want to install it. with a lil work and time i think we can get this thing fully rooted .. The kernel

is most important to me cuz this thing needs to be overclocked to atleast 1.2ghz..
[Gen8 General] chrulri:
you don't want to fully root and reformat everything and may brick your device. it's just not worth it.

use the SDE: install custom kernel and if your satisfied remove default kernel and it will boot only custom kernel (until you install any archos firmware again)

with SDE you can use full internal storage (kernel is stored in another very little flash chip: /dev/mmcblk0, mmcblk1 = internal storage, mmcblk2 = sdcard), reformat it and install and do whatever you want. if you're not satisfied, start in recovery mode reformat the device and start all over again or install the archos firmware again. no real chance to brick your device.

why would anyone try to brick his device if he has full device access for free?

@topic building custom kernel and cross compile some linux libraries is quite easy, I'll post an HowTo and some shell scripts today or tomorrow, ok?
[Gen8 General] txtmikhail:
I want full root to do wat I want..I have a epic 4g wit root and a custom rom..one ...I don't need to boot up wit dual boot for the same os...

[Gen8 General] fullthrottleenergy:
Once we get root and a recovery image installed bricking the device is pretty hard to do. I seriously haven't heard of any people bricking their phones (other then people flashing different radios - gsm for cdma and vice versa). Rooting and making a 100% ASOP rom would kick ass. Not sure what archos was thinking for making it impossible to root. dumb decision. fail
[Gen8 General] chrulri:
how would you install a recovery image to a bricked Gen8 device??

there is no need for dual boot but an option in the recovery menu called something like "remove android kernel" which removes the default kernel so the device boots custom kernel only, no dual boot if you don't want it.

You have full root access with SDE, tell me what you can't do with SDE? :rolleyes:

SDE = recovery bootloader --> nearly unbrickable device
[Gen8 General] jerdog:
A HowTo on this device would be great. Thanks!

As to custom ROMs, etc. - I echo other comments above. I have never had anyone truly brick their device doing custom ROMs - I work at a carrier and have not seen a truly bricked device that couldn't be undone with a custom recovery and/or reflash back to stock and locking NAND again and noone is the wiser. We can put together custom kernels all we want, but a lot of the holdup in devices is the bloatware that the manufacturers put in - and a lot of it is behind the scene in the frameworks. Just doing a custom kernel is great - but to unleash the real potential of the device is to remove all the unnecessary options and software and libraries that are not needed.

Not sure who all here has dealt with Android phones and the custom/AOSP/CM environment, but going to AOSP (or CM) without all the manufacturer bloat and only including the necessary drivers and such will show you how much of a performance boost and unending promise a device truly has. The possibilities are endless.

THAT is why we desire to have NAND unlocked and the ability to move this device to take full advantage of it's hardware.
[Gen8 General] chrulri:
HowTo is online: [HOWTO] Build custom kernel, libraries and applications on your own
[Gen8 General] chrulri:
you can replace the whole operating system, archos ships per default some buggy angstrom linux with SDE. maybe someone is able to put ubuntu or windows phone 7 onto it if he is crazy enough ;)

What do you mean with NAND? The Internal Storage (A101IT - 8 or 16 GB) or the flash chip where the kernels and the default android OS are stored?

eitherway, both are NOT locked. you can remove and replace the (signed by archos) squashfs from /dev/mmcblk0p2 and put your own android or any other operating system in it. or reformat /dev/mmcblk1 (internal storage -> 8 / 16 GB) and install your own operating system (e.g. some stripped ubuntu)

Gen8 devices aren't locked. Install SDE und you can do whatever you want with only little possibility of permanently brick it. you always can reinstall the archos firmware to restore default android OS
[Gen8 General] Kevin187:
I'm looking forward to a clean/vanilla 2.2 rom with all bloat removed!
[Gen8 General] jerdog:
NAND refers to the flash chip where Archos (and all other manufacturers) put their system files.

When you delete something from the Archos OS (i.e. /system) and then reboot, does it show back up or is it permanently removed? Are you able to remove ALL traces of Archos' stock Android implementation?
[Gen8 General] chrulri:
yes you are.

install SDE

boot up the shipped angstrom linux

mount /dev/mmcblk0p2 and remove the androidmerged.squasfs.secure file inside

reboot to recovery mode and "uninstall android kernel"

reboot

without the default archos android kernel it boots always to the custom kernel (default: angstrom linux, but can be replaced with any other OS)

now you have a gen8 device without any archos android os and can use for whatever you want it

if you want it back to normal: recovery mode -> reformat device & install archos android firmware
[Gen8 General] jerdog:
Aren't you just removing the kernel and putting your own in? The partition with the actual system still exists though, correct?

What it seems to me, is that Archos has given the ability to use your own kernel with their /system still in place - but this doesn't give the ability to install a completely vanilla system (ala AOSP and/or CM) or to strip out the bloatware and modify the existing frameworks....
[Gen8 General] chrulri:
I hate to repeat myself.. ( is my english really that bad? )

You DON'T replace the kernel, you install just another one (called custom kernel).

You CAN remove the archos' kernel (but you don't have to)

You CAN remove the archos' android filesystem (location: /dev/mmcblk0p2 -> androidmerged.squashfs.secure)

You have WRITE ACCESS to all flash devices (/dev/mmcblk[0-2])

When you install SDE it ships a vanilla angstrom linux, this has nothing to do with android and shows that you are ABLE TO INSTALL A COMPLETELY VANILLA SYSTEM (even side by side with archos' android if you want to)
[Gen8 General] heffe2001:
chulri, I think you're missing the point. He wants the entire system opened up. Even though you can use SDE to write to any of the flash devices, can you use it to remove a single App from the existing android setup?

They (and I actually) are wanting a custom recoery (something ALA Clockworkmod would work fine for me), and have full access to the internal nand, so they can flash a completely custom ROM, or a pre-rooted factory rom, etc. They want this WITHOUT having to use SDE. With the squashfs secured like it is now, this makes it a bit more difficult to get what we're wanting... If we have a full system rom that's not secure like the existing one, then any app could be removed, upgraded, or themed however you want.

If you don't already own a rooted android phone, then I don't think you really understand the WHY of what they are asking for.
[Gen8 General] chrulri:
and again...

you can install whatever you want, and even if it is a customizied archos android :rolleyes:

the squashfs is not encrypted, you can unpack, copy and replace it with an unsigned squashfs image or even another filesystem, install a custom kernel which ignores the signature (change one or two lines in initramfs.cpio.gz) and there you go...

why do you need another recovery image when you have SDE? it IS a recovery image..
[Gen8 General] heffe2001:
I had thought the squashfs image was secured, which it's good to know it's not.

As for the custom recovery, it's more of a personal preference. Most people would rather have some sort of AOSP rom installed on their system, with none of the custom Archos stuff on it, no dual-booting, etc. And while it may be your opinion that it's not necessary, people want it. Being condescending whenever people request it or even ask about it doesn't help at all (all the :rolleyes:, or is my english that bad, etc).

I use clockworkmod on my Incredible, and it's never once told me i had to have my device plugged into power to flash something, but I'm stuck at work right now with my Archos telling me that to flash my system with their SDE I have to have it plugged into the power adapter (even though I have 100% battery). That alone to me (again, TO ME) is justification for a seperate custom recovery...
[Gen8 General] chrulri:
after you have installed the sde you don't have to plug in power to flash custom kernels :p

anyway: only because some people want some own recovery image, go ahead, hack the sh!t out of gen8 and may brick it but for god sake don't tell the world you couldn't do the same with SDE and claim about the bad bad fail fail company not letting some stupid users brick their devices :D the ones who know how still can do whatever they want, with or without SDE. the ones who doesn't.. um.. nevermind ;)
[Gen8 General] jerdog:
Thanks for putting it better than I was trying to get at.
[Gen8 General] fzelle:
@heffe2001:

@jerdog:

Nearly every mobile needs some kind of hack to get a recovery to work.

For the gen8 this hack is the SDE and it is official.

In a few weeks there will be complete customs roms that will be easyly installed.

So where is your Problem?
[Gen8 General] heffe2001:
I don't have a problem with the SDE (I have it installed now on my 70), but it's about choices. Some people out there would rather use something other than the official recovery. I personally would like to see clockworkmod, as I like to keep nandroid backups of the system when I make changes, just in case something does go screwy (and don't throw up the argument that you can't brick these tabs due to the SDE being on there, it's still possible, however unlikely that may be). I didn't see nandroid, or backup of any kind in the SDE menus, someone correct me if I'm wrong.

To me that's the beauty of an android phone over just about any other, you have choices as to what to run on it (for the most part anyway, I'm sure there are some android phones out there that nobody's bothered to open to load other roms, etc). I guess I just don't get all the adamant "You don't need it because they already supplied one" posts.
[Gen8 General] blazingwolf:
It's just as easy to say I don't get all of the adamant "I have to have a custom recovery" posts when one is already available to be used freely.
[Gen8 General] heffe2001:
I've never said I Have to have a custom, I said I would Like to have clockworkmod recovery. I don't care for the supplied recovery. I would rather not use the boot men, would like to have the ability to do a nandroid backup.
[Gen8 General] chrulri:
why not use the supplied recovery to install a custom recovery? :D
[Gen8 General] _nz_:
and chulri keeps telling you that you can do almost all you want using SDE... you can run your kernel and your NAND content, so what are you missing? you can even go ahead and flash your own bootloader after you are damn sure that it will not brick the device, because if you make a mistake you have brick. So, if you are not that damn sure, then just keep using our (SDE) bootloader...
[Gen8 General] _nz_:
please ignore this one :)
