The latest news about RK3288

Re: The latest news about RK3288

The history from manufacturers is:

"Rockchip did not allow us to say A17 before, now they do not allow us to say A12". The boss of a design house called me to visit his office next week, I will try to remember this question.

About the A80, looks good:

Merrii is doing good development boards like the Humminbird or this one. Just the lack od documentation and community is the problem. I was talking with their english speaker sales and does not look like they put attention in my questions (anyway invited me to visit their office and explain more, but I dont really have time for now...).

Its clear Rockchip knew they were in breach of ARM's licensing back in January 2014 at CES 2014 but they've since continued to mislead their customer base with false A17 advertising in fear of damaging their reputation.

ARM's website also state,

'The Cortex-A17 processor is architecturally aligned with the broadly deployed Cortex-A7 processor, enabling next-generation mid-range devices based on******big.LITTLE******technology.'

CNX Soft have written a great comparison of this years SOC's.

And the unkown T764 is another story...

I agree, Rockchip's methodology and reputation over the last twelve months has been questionable.

I have seen that picture months ago, they said because can not promote the A17 in that moment

Could it be that the latest iteration of 3288 is now compliant, therefore able to advertise as A17?

An interesting find within the file system of an RK3288 tablet.

Is there not a diagnostic app available that can accurately determine whether the RK3288 is A12 or A17?

I did see a video from an exhibition demo that showed just how big.LITTLE worked in real time, with a simple graphical representation of how the CPU's were being used.

As you correctly suggest, ARM says big.LITTLE is a feature of an A17 with 8 cores, which the RK3288 does not.

NOT A17

I have an RK3288 and it is NOT CORTEX A17, according to the kernel messages.

Also of note, anyone considering paying a premium for Cloudnetgo tv boxes might want to take a look over at this thread:

http://www.freaktab.com/showthread.php?16682-Bluetimes-RK3288-boxes&p=224988&viewfull=1#post224988

I was after a certain Bluetimes tv box to confirm it has the same pcb as Cloudnetgo CR12 - and upon receipt of the device my suspicions were more than upheld...

I can live with an A12 but I don't like to be fu**ed...

Do you have a link?

This was the one that I saw the one from Shomari does demonstrate it well.

Ok, I had hoped I could identify some tools, but it's only a marketing video...

EDIT:
ok, the second link is a little bit more helpful... I think they use the known directories (at kernel) to determine the values via USB... but I think no way to get this program...

They're just essentially charting the core utilization per activity much like any other cpu monitoring app. Then they dressed it in their fancy branding. Other than that any cpu monitoring app run against a BIG.little chipset will output the same data.

Well, today I have been with a member of ROCKCHIP, so I connected a RK3288 board to my laptop by OTG port, opened my windows cmd, adb shell.....

cd sys/devices and there was the "ARMv7 Cortex-A12"

He said must contact ARM to know more about this and give me a reply, we exchanged contacts and also have been talking about the 4K - 60Hz, he said this is already fixed, even they bought some TVs from Japan directly to test this.


Well... more news soon about this as I have direct contact with Rockchip guys.
