This weekend, my mother in law purchased a used Acer Iconia A100 from her son. She asked me to give her a crash course on it.
So I'm looking, at it, not bad. I'm like this thing has ICS 4.0.3... Cool... I decided to look at the specs... Yep, it has the Tegra 2... I'm telling myself there is no way this thing works in the video camera... Well, shockingly it works perfectly!
So why in hell does the Acer Iconia A100 vid cam works with ICS and not our phones? I verified the Acer site and they only have Honeycomb in terms of OS. So I guess my bro in law updated it himself but what I'm really pissed off at is why the video camera works like a charm on his...
WTF?
No!

What I'm guessing is ics isn't that much of a big leap from honeycomb, or he just changed the build.prop to 4.0.3 to make him feel good about himself.

That table got an official ICS update last April:
http://www.androidpolice.com/2012/0...rly-to-some-lucky-users-download-link-inside/
Which puts LG to shame regarding its lack of ICS updates for existing devices.
OK must of been Acer Canada that's behind in their updates!
But with that said... That means the basic drivers and code are probably available for the Tegra 2 for ICS if Acer was able to get it running... Sorry, far from being any type of programmer but do we really LG to do anything here or can any Dev pic off some code from the ROM on the Acer and work some magic.
NVIDIA just supplies the chip, the Tegra 2. It's up to the phone manufacturer to design the phone with a chipset and software. Every phone manufacturer is different so they must write different drivers.
The phone manufacturer is responsible for the drivers. It's not NVIDIA, it's up to LG and Acer to provide drivers for their chipset. Understand?

NVIDIA provides full-featured drivers for their SOC which the original equipment manufacturers (OEM) apply to their devices. The OEM enables/disables various driver features and tests their operation. If bugs/problems are revealed with the drivers, the OEM consults with NVIDIA which may cause NVIDIA to generate another driver. It is an iterative process. Even the latest NVIDIA driver for ICS for the Tegra2 AP20H has known bugs. I think the NVIDIA driver problems is what's partly to blame for the delayed release of ICS for phones with that SOC.
Just a reminder that people are forgetting that the Tegra 2 in our phones is a completely different chip than a Tegra 2 elsewhere. Numerous phones have ICS with a Tegra 2 chip working fine, but those are not ones that use the same chip as ours.
Thanks for that clarification guys! Makes more sense now! :good:
Well sucks for LG then because this doesn't really encourage me to purchase another LG device in the future.

Hi all. Just finished ordering this tablet that is currently running cupcake. Would love to root it and install a custom ROM. Any info on how I can achieve this?
Thanks in advance
offtopic... does the apad run any good? is it smooth?
Why is it off topic. It is a tablet that runs android. Do not have it yet so can't comment on how good or bad it runs.
i was asking an off topic question (i.e. not related to your question). guess i phrased my sentence wrongly. do post here on how well this device seems to perform.
I will. Thanks for your intrest.
You should of waited for the Notion's ADAM
I only paid $100.00 US for my tablet. This one is considerably more.

hey could you pm me the site where you purchased it from?
could you update your main post with the specs that you ordered from? Apparently there are Apad clones with crappy processors instead of the rockchip processors
Dealextreme has it for cheap
dealextreme is the crap version. the proper apad is the one with rockchip in it. and i found out that the cheapest apad with rockchip is ~150usd
i have one of those too.
with the rockchip which actually is not to bad of a processor. nowhere near the A4 but ok to work with.
it's an ARM derivative and consists of a cpu and dsp(gpu).
i would also like to know if anybody has played with it yet.
i followed the android instructions of building a development envirnment and have the tablet actually show up in eclipse but where to go from here?
sorry for threadjacking a bit
i would first of all like to be able to upgrade android. if possible 2.2 or at least to 1.6.
the device has the upgrade locked.
the are also language option conflicts were suggestive text and some keyboard keys still show up in (i guess) Chinese.
It'll most likely be impossible to upgrade the apad to 2.1/2.2 as rockchip dsp isn't actually a gpu, its a video processor for videos only.
on another note i have decided to pass up on the apad as it doesn't seem that "future-proof" most likely will get this http://www.wiipad.us/product.php?id_product=11 unless better options come out in the next 1 month or so
does android 2.x require a specialized dedicated gpu?
the dsp is essentially a gpu, it is capable of playing 720p video.
it should be plenty for android 2.x to get around
so i can move files from the device to the pc.
i copied the data and system folder.
what to do now?

Yeah but it decodes videos only, a gpu actually pumps out the graphics which is an intergral part of 2.1 onwards (also in the rockchip's specs i saw somewhere this chip does not support 2.1) The wiipad neno has a cortex a8 core which is similar to the ipad's processor so it is running on 2.1.

ive been digging around at Apads for weeks.. and i havent really found one i was impressed with.. i thought about going with just something to play with a lil bit and get the EKEN m001 or w.e modle it is.. but i just couldnt get it at a price id be willing to shell out and be ok with.. but this wiipad.. with android 2.1 deff has my attention especially wit a 1ghz processor.. and with it having a 16gig nand flash at a price of 267.19 i will shell out the money.. cuz thats exactly what i want.. but i to will wait for more reviews on the product.. but please post what you think about the one you orderd OP cuz i am intrested in that one as well.. and can you PM me the site you got it from for 100$?? please and thank you.. and im very happy to see these Apads (android tablets) showing up in the forum!! i cant wait for a few devs to jump on board imagine the roms and custom stuff i feel like a kid ina candy store already
Not sure if this should be in the Dev section, but it looks like NVIDIA released the OS images for the Tegra development kit...
http://developer.nvidia.com/content/android-40-ics-os-images-tegra-android-available
Hopefully this helps the Devs working on the ICS port for the Gtab...
is for ventana
not for harmony
i believe that nvidia axed support for harmony but released a 2.3 image as last uptate for that platform

So does this actually provide no support for the gtablet?

Nope. Different platform, nvidia kinda screwed us on that front.
Actually this release does help us out a lot. Give it time, but this release enabled HD video decoding on Gtablet ICS. I know because I've tried it.
I was just wondering, the viewsonic gtablet is a tegra 2 harmony device and the guys at team drh have made a kernel for ics that is fully hardware excelerated so my question is since the g2x is a harmony device can the drh kernel be used as a base for a working g2x kernel with full video decoding just like the gtablet???
Harmony is for tablets. We have Ventana.
Closest best is the ZTE Mimosa X which has ICS and the Ventana. When it drops hopefully we can grab the drivers from there.
From the 2x side:
msedek said:
If porting full working drivers were possible in any way from any device to make o2x runs with everything working on ics it should be done by now.. Al the things you are thinking now developers though about it long time ago... I'm developer myself.. Just not android developer.. I develop in assembler for microcontrollers as I am electronics engineer, and trust me there's nothing that I don't know about the chips I work on...
Every microcontroler (I'm specialist in microchip) has different libraries to access the different modules... As microchip produce open source libraries I can access all the functionalities in the processor and microchip provide the full pdf with the instructions set for every processor.. But even chips from the same family with a minimum variation like let's say pic18f478 to pic18f478a can have bunch of different modules with a bunch of different libraries...
So once I can develop a function out of the instructions set (what's called here from scratch) I can then develop a library wich I can call in my main software every time I want the processor execute an action... So in this case Nvidia won't provide their instructions set for their processors... They only provide libraries to oems... And oems can develop procedures and functions with these libraries...
That said Nvidia has no responsibilities here... Because no matter what os oems use the chips and the libraries are the same and the method to access chipset function won't change from one os to another... That's processor architecture and can not be modified..
LG has to re develop the function and procedures to work with the new os that is low level (assembler compiled) and embedded into the os... Those functions are way different from one device to another and it's not possible to use them unless it's the same exact chip family with no variants...
Devs here can not develop functions because they don't have access to the libraries... They only have access to the final product or what I could call the UI for developer.. And that's the DRIVERS..
That's it..

Are you sure about that everything i read said g2x was a harmony board and its not as simple as one is phone one is tablet the Motorola xoom is a ventana board i do believe its more to do with components like memory and amount of memory sound chips and how they are implemented together

Naive but
Not sure I get the problem...isn't android really a linux clone with less stuff? Wish I knew more about how this works.
Just a thought seeing as how us G2X and O2X folks are waiting patiently for ICS drivers to arrive if ever from LG. Article hitting a few Android sites has Sony releasing a PMP w/ a Tegra 2. Now there is no mention if this Tegra 2 is the same as our devices but hey here's hoping. Thoughts?
http://phandroid.com/2012/07/18/sony-introduces-walkman-f800-with-android-4-0-launching-in-august/
I read somewhere that this will be the Ventana (same as the G2x) and not the Harmony chip. This makes sense, since the Harmony chip is used almost exclusively in tablets. I can't find the article, so I don't know if this was speculation by the blogger or something official.

very unlikely to be ventana as that is a development board that lost support from nvidia a while back. thats why you havent seen many, if any at all, ventana based device released since harmony became available. think of ventana as the beta version and harmony as production release. there are no distinction of which version to use for tablet vs phone

I don't get it, what exactly is the difference between the two? Is Harmony faster or use less power or something? Because doesn't it have all the same clock speeds, cache, RAM, etc...??
The problem will probably be in the fact that we don't have the driver source. If the driver is compiled for ICS it may work but I'm pretty sure we'll still need the driver source code or a driver compiled specifically for the G2x/O2x. Here's to hoping though.

As far as I know, the ONLY difference is the GPU. Ventana is clocked at 300Mhz for the GPU and Harmony at 333Mhz.
Never will these drivers be released for this device. Those numb nuts at NVIDIA are waiting for this device to die.
http://www.androidcentral.com/zte-grand-x-hands
This is the closet you're going to get to the G2X/O2X interms of GPU wise.
I hope the devs can cook something up. There are a few devices that are coming out with Tegra 2 and Ics. Keeps fingers crossed . If not then on to HTC and lg never again

According to CNET http://reviews.cnet.com/mp3-players/sony-walkman-f800-32gb/4505-6490_7-35396728.html
this is a device that has tegra 2 chip and is running ICS, explain why we can't take the drivers from this device. I understand it is not a phone, but don't we just need drivers for the graphics tegra 2 processor and not the actual phone part of our phone.
P.S. how is it a walkman gets ICS before our phone.
Most likely won't work because we don't need the graphic drivers, but but specific p999 drivers that link tegra 2 soc to the parts of the phone. We have graphics already, but we need the drivers/source that allow the devs to 'connect' individual components together on the main board I believe
We need hardware acceleration drivers and hardware acc. means gpu rendering.

If that is true how come everyone is saying as long as any phone with tegra 2 gets ICS we can get the drivers? Wouldn't that be the same issue as getting the drivers from this device?

My understanding is that they originally thought that, but after the ZTE Grand X (Same SOC running ICS) was released they realized that this would not be so simple to do.
