I'm waiting a Rockchip reply yet...
The A80 development board's new price: http://www.aliexpress.com/store/prod...015735541.html
Shipping is really expensive I think. I don't know what price I can get here in China... if have time we will ask Merrii.
(Edit): Just asked Merrii about the A80 board, price is same in China.Last edited by Javimetal; 09-12-2014, 11:11.

(45-nm is ARM Cortex-A9 (0.8 -2GHz))
But it says 'ARM 0xc0d' which seams to be an A12 ("The CPU architecture is 0xc0d, which stands for ARM Cortex A12, whereas Cortex A17 should be 0xc0e" http://www.cnx-software.com/2014/08/...ndroid-tv-box/) "seams to be" because the blobdiff isn't longer available at the kernel.git but you can also find it e.g. at http://gcc.gnu.org/ml/gcc-patches/2013-12/msg01390.html
Here you will find a blobdiff including the define for the CORTEX_A17 https://git.linaro.org/arm/ds5/gator...driver/gator.h
Have you other useful tools?

Even as I posted I was thinking it doesn't seem possible that it can be built using 40nm. No way the processors would run at the speeds they're running at current voltage levels.
edit: ...also, why would they go from 28nm to 40nm after releasing the RK3188 on 28nm. Doesn't make sense but who knows.

When we see mass shipping of 4288 devices and the media techs get hold of them for full reviews, it will be interesting to see how many ask the same questions.

1. Both companies are colluding to mislead, which I can't really believe would be true.
2. The naming conventions are not strict enough to allow every combination to have some kind of unique identifier, which would be down to Arm to resolve for the benefit and clarity of both vendors and buyers.
3. The 3288 has potentially had further development since it's original marketing that gives it credibility.
4. Rockchip are pulling a fast one and hoping that Arm aren't that interested enough to make them change the marketing. After what they did with the secret release of the 3188T, I would not put it past them.
With Intel partnering up with Rockchip, the relationship between them and Arm should become interesting.

Everywhere it shows RK3288 is a 28nm chip. Shomari where did you get the info that the RK3288 is built on 40nm process?

...yup.
